Why do I receive this error message: “The Microsoft Jet database cannot
open the file”?
Your Windows profile holds all of your personal user settings on a given
computer. When you log in for the first time on a computer, it is created for
you. After that, it is loaded when you log on using your domain account, and
includes user-specific settings such as what programs you have in your
desktop, the color of the background image, your mouse settings, and your
printers.
MAR 664-00
If you have received this error message after installing new channel sets or
screens check the file attributes to ensure that the files are not “Read Only”.
To check the file attributes use Windows explorer to locate the most recently
added channel or screen file right click the file, click on properties, uncheck
the “Read Only” box and save.
Note: You must be logged on as an administrator or a member of the
Administrators group to run Biograph Infiniti. At minimum you must be able to
write to files. If your computer is connected to a network, network policy
settings may also prevent you from completing the procedure. Please see
your Systems Administrator for the applicable privileges.
When installing BioGraph Infiniti, why do I receive this error?
Unable to read source file……”
Possible Cause
“Error 1311:
This error indicates that the installer is unable to access the necessary files
from the CD-ROM drive or when the "Restrict CD-ROM access to locally
logged-on user only" local security policy in Windows is set (See ERROR:
1335).
Why do I receive Error 1335: “The cabinet file Data.cab required for this install
is corrupt” when installing BioGraph Infiniti software?
Possible Cause:
Dirt or smudges on the BioGraph Infiniti or Suites CD-ROM, or dirt and dust in
the CD-ROM drive itself often cause this error.
To resolve this error, make sure that both the BioGraph Infiniti or Suites’
CD-ROM and your computer's CD-ROM drive have been cleaned, and then
perform a hard disk installation.
To clean a CD-ROM:
Hold the CD-ROM with the shiny side up. Check the CD-ROM for visible dirt
and scratches by tilting it slightly to reflect nearby light.
If dirt is detected, use a soft, lint-free cloth and wipe the CD-ROM from the
center in a straight line to the edge.
For CD-ROMs that have excessive debris on them, consider using a gentle
stream of warm water in combination with the soft cloth.
Note: For scratched CD-ROMs, contact your place of purchase or Thought
Technology Ltd. for a replacement disk.
Dirt and dust often accumulate in the CD-ROM drive. To loosen this dirt, blow
carefully into the drive. Canned air, available at most computer supply stores,
can also be used for this purpose. If you are unable to manually clean the
CD-ROM drive, consider buying a retail product designed to clean the drive.
If you do not feel comfortable performing the procedures mentioned above,
contact a computer hardware specialist.
To perform a hard disk installation of BioGraph Infiniti or any of its Suites, use
a flat folder:
Close all applications that are running, and then restart your computer.
Save a copy of the “disk” folder that is on the BioGraph Infiniti or BioGraph
Infiniti Suites CD-ROM to your computer's hard disk:
Right-click the Microsoft? Windows? Start button, and then choose Explore.
Create a new folder at the root of your hard disk, and then name it Flatfile (for
example, C:\Flatfile). (For detailed steps, please refer to Windows Help).
In the same window, browse to the drive that contains the BioGraph Infiniti or
MAR 664-00
Suites CD-ROM, and then copy the entire contents of the “disk” folder on the
BioGraph Infiniti or Suites CD-ROM into the C:\Flatfile folder:
Click the CD-ROM icon (or DVD-ROM icon), and then browse to the “disk”
folder and open it.
From the Edit menu, choose Select All, and then choose Copy.
Locate the Flatfile folder you just created, select it, and then choose Paste
from the Edit menu to copy all the files from the BioGraph Infiniti or BioGraph
Infiniti Suites CD-ROM.
Note: If any errors occur during step 3, there may be a problem with the
BioGraph Infiniti or Suites CD-ROM, the CD-ROM drive, or your hard disk. If
possible, try to install BioGraph Infiniti or Suites on another computer to
determine whether the problem is with the CD-ROM or the original computer.
(If the installation fails on another computer, see the Note above about
obtaining a replacement disk.)
Restart your computer, and then install BioGraph Infiniti or Suites by doubleclicking the setup.exe file in the C:\Flatfile folder located on your hard disk.
Why do I receive this error message: “The number of detected encoders does
not match with the channel set. Check the hardware connector or turn
encoders ON/OFF”?
Possible Cause:
If you get this error message, it's probably because the program is unable to
detect the encoder on the USB or COM port to which it is connected. Try the
following troubleshooting sequence:
Make sure that the encoder is turned ON. If you turned the encoder on after
clicking OK at the previous step, try again.
If the device is ON, look at the power indicator. If it is blinking, the batteries
need to be changed.
Verify that the fiber-optic cable is well inserted all the way into the encoder's
output connector (about 1/2 inch).
Verify that there is a bright red light at the tip of the other end of the fiber-optic
cable. If not, verify if the cable is damaged. Sharp bends can prevent the
signal from traveling through the cable.
Verify that the fiber-optic (F.O.) cable is well inserted in the F.O. Input of the
TT-USB or PRO-SB Interface device. Be careful not to insert it in the Switch
control output (it fits). The F.O. Input is a plastic knob that can be loosened or
tightened.
If you are using a PRO-SB Interface, make sure that it is connected to a
proper Serial Port (COM 1 or COM 2, usually) via the 25-pin to 9-pin Serial
connector converter.
If you are using a TT-USB device, unplug it and re-plug it. Windows XP should
emit warning tones signaling that a USB device has been disconnected and
reconnected. If you get a "New Hardware Device Detected" message, then the
TT-USB device may not have been properly installed. Please refer to the
Installation instructions in the hardware manual.
If the encoder has been used with other software systems, you may see the
error message shown below. When this happens, you can either modify the
DIPswitch settings on your encoder, to match the communication protocol
required by the selected channel set, or select a different channel set to work
with. For more information, please read DIPswitch settings.
MAR 664-00
If you are using the TT-USB and none of the above solutions fix the problem
you may have to uninstall and reinstall the Thought Technology USB driver.
To uninstall the TT-USB driver right mouse click My Computer, click
Properties, click Hardware tab, click Device Manager, click on the (+) of the
Universal Serial Bus controllers, right click Thought Technology TT-USB
device, and click uninstall. Close the device manager and restart your
computer.
When Windows display the notice find new hardware device follow the
prompts.
When a Hardware Installation or Software Installation warning that the
software has not passed Windows logo testing to verify its compatibility with
windows XP. Click the Continue Anyway button to complete the driver
installation.
Why do I receive this error message: “The communication protocol type does
not match with the channel set. Change DIP switch position and turn all
encoders OFF/ON”?
Infiniti Encoder
DIP Switches
On the Infiniti encoders, the DIPswitches are located on the underside of the
encoder, just to the left of the belt clip. There are four switches that can be
flipped up and down to a 1 or a 0 (zero) position with the aid of a paper clip or
small pointed object. We recommend using the tip of a paper clip to change
the position of a switch. Avoid using pens or pencils as ink and lead dust can
damage the switches. Also, be sure to always turn the encoder off before
making changes to the switch settings.
To set a switch, push it down. On the following graphics, the side that is
flipped up is shown in white; the side that is pushed down is in black. The
illustration shows a switch set to the 0 position:

BioIntegrator.
Why do I receive this error message: “The Main Screen has not been loaded”.
This message appears because a change was made in either the channel set,
the screen or the script. In the BioGraph Infiniti Software channels are
associated with screens and scripts. If a change was made to the channel, the
screen or the script, the link could be severed.
Note: If you need to modify a channel set, screen, or script, copy and rename
before you make changes.
How do I use the files with the purple Infiniti icons on the desktop?
The Infiniti icons with Suite names are links to portable document format files
(PDF) which contain screen captures of display screens, detailing channel
sets, categories, screen names, overviews and purposes of screens within
that suite.
The screen description at the beginning of the document is linked to the
document page with the screen notes. The Suites themselves have been
loaded up to your BioGraph Infiniti.
Can I use an EEG Flex/Pro Sensor in a channel set configured for an EEG-Z
Sensor?
Yes, Start Session, choose the Client, choose the Session type, Session
setting, select the Channel Set then select physical configuration, highlight the
sensor, and click on ”Toggle” when the appropriate sensor appears click on
“Overwrite Original Channel Set”.
What is the use of the Compact Flash?
The compact flash (CF) is used as an alternative storage medium for data
being recorded by the encoder. The CF card is a small square approximately
the size of a box of matches and is inserted into the rear surface of the
encoder with its label facing up. The encoder is delivered with a protective
insert in the compact flash slot. To remove it, push the button next to the slot
once to eject the button, then push again to remove the card, pushing the
button back in. The CF card can then be inserted; you will notice that the CF
card can only be inserted one way into the encoder to protect from incorrect
insertion. When inserted properly it will be flush with the encoder rear. Follow
the procedure above to remove this card when no longer required, and reinsert the protective insert. CF cards require a CF card reader to transfer data
to the PC.
Do I need any special make of Compact Flash card or Card Reader?
Compact Flash cards and Card Readers can be purchased from most
computer stores.
Note: Users should follow the appropriate procedures used for disconnecting
peripheral devices when unplugging the Compact Card from its PC reader.
Does the Compact Flash card need special formatting?
Before its first use in the encoder, a CF card requires PC formatting using the
file manager. With the CF card inserted into the reader connected to the PC,
MAR 664-00
from Windows® open the file manager and identify the Removable Drive.
Right click the removable drive and select Format.
Select Format Type Full, if using Windows® XP select file system FAT, not
FAT32, and select Start. When this is complete use the single master file
build function provided by the Infiniti Software to finish the process.
Note: Formatting CF Card with File System other than FAT will render it
inoperable.
Is there a way for users to create their own screens for BioGraph Infiniti?
To create screens in BioGraph Infiniti you will need to have the Developer
Tools, which consist of the Channel Editor, the Screen Editor, and the Script
Editor.
How does one create new virtual channels?
Virtual Channels are created using the Channel Editor.
Why don’t my Suites start when I click on the desktop icon?
The desktop icons are linked to portable document files (PDF). The PDFs
contains screen captures of screens that list the channel sets, category,
screen name, description, overview, and purpose.
Can you synchronize a video camera with a psychophysiological recording
session?
You can use up to two web cameras, and the synchronization is built into
the BioGraph Infiniti software. When you click “start recording”, the data and
video will be recorded in a synchronized way. Refer to known issues.
When the system is recording live, is there any means of annotating the
recording to mark events such as change in posture? In other words, can
you put a marker while you are recording data?
Yes, you can simply tap the space bar to place a marker. You can do this
while recording data, if an event occurs that you would like to mark. A
marker, shown as a vertical dotted line, will be placed at that moment in the
session data. When reviewing the session, you can find the marker at or
near that moment and easily type in a label to describe the event that you
wanted to mark.
Can I use the BiographX animation CD on the new Infiniti system?
BiographX animation CD is not compatible with the new Infiniti software
programs. However you can still use them with the old BioGraph 16 bit
software with the new Infiniti encoders. Most of the BioGraphX animations
have been reformatted and are available on the Legacy and Multimodality
Suite. By using Screen Editor Lite you can choose from a list of animations
& graphics to replace the ones in the existing screens.
If one or more sensors are missing, but I still want to go ahead and record
the session, what should I do? Do I need to edit the screen, channel sets
etc.?
A message box will pop up, asking you if you want to continue recording the
session without those sensors. Just click OK and you can start recording.
The exported client data cannot be read, and shows flat lines. Why?
The file attributes of this session probably got changed when a "Read Only"
MAR 664-00
medium, like a CD or a DVD, was used to back-up the session data. This
does not happen when Zip Drives or Flash Card memory drives are used to
transfer data from one system to another. It also doesn't happen when
session files are zipped to a single archive file before being burned to a CD.
You can change a file's attributes by right clicking over it and selecting
"Properties". At the bottom of the dialog box, you can see a check mark in
"Read Only." Remove the check mark to make it accessible from BioGraph.
Can you display all the recorded data on one screen and then zoom in to
display a page of data (maybe 1 minute) and select as appropriate?
Yes. The Time Frame Settings drop-down list includes a “size to session”
option that shows the entire session. You also have options for other time
periods including 1 minute.
Can you analyze heart rate variability and respiration, measure the degree
of alignment of them, and get the amount of shift required to best align the
two variables?
You can display heart rate variability and respiration on a multi-line graph
giving you the ability to analyze them.
The heart rate variability system displays a running Fourier analysis graph.
Is it possible to do that with any parameter measured, and if so, can the
display parameters be varied e.g. the scales of the graph?
A running Fourier analysis graph can be used to display EMG, EEG or IBI
(inter beat interval). These are the only signals for which this can be done.
Scale settings are adjustable.
When exporting data in CSV (text) format, can the format of the data be
adjusted? In particular, if the sample rate is not adjustable, can the export
sample rate be adjusted so that data is not exported in a memory hungry
format (text format) at a sample rate of 2048 samples per second (unless
the data is actually required at such a rate).
The CSV (text) format is the only available format for the export of data. It
was chosen as the lowest common denominator to ensure that users could
import the data into their choice of software. The export sample rate can be
selected at 4 different re-sampling rates; 2048 Hz, 256 Hz, 32 Hz or 8Hz.
The start time and end time of the data to be exported can also be selected.
On analysis of (say) heart rate change, can you place a cursor or mouse on
a point on the trace and get a read-out of the instantaneous value of the
parameter measured at that selected time?
Yes, in review screens you can use a Time Mark, which is a vertical red line
that usually sits at the extreme left of line graphs. You set the Time Mark to
the tip of the mouse pointer.
Is the BioGraph Infiniti Software able to do coherence?
Yes, it can. There is a coherence virtual channel computation in the Infiniti
Channel Editor software. The Multimodality Suite calculates the coherence
between two separate EEG channels on a scale of zero (0) no coherence,
to one (1) for perfect coherence. The BioGraph Infiniti software also can
display coherence for specific frequencies or a range of frequencies such as
Alpha.
MAR 664-00
Do AVIs created using the cinepac codec work with BioGraph Infiniti?
Windows is distributed with a number of audio/video codecs. MS has a
couple of them, MS RLE and MS Video, but they are older technology and
not too good. For the longest time, Windows was also packed with Indeo (by
Intel) and Cinepac (a MAC codec). In the summer of 2003, MS had a fight
with Intel and decided to remove the Indeo Codec from its distribution files
(this was done when a Service Pack was installed). Of course, this removal
had a lot of consequences with other people's multi-media packages: Many
Web Cams, video games and 3D graphic programs stopped working.
People complained and MS had to re-release the codec through a special
update package that can be downloaded from their Tech Support site and
which TTL is now distributing on the Setup CD for BioGraph Infiniti. Cinepac
is the one that TTL settled on because it allows some non-standard sizes
(ex. 120 X 600 pixels). Most other codecs tend to work only with standard
sizes and proportions (ex. 640 X 480). So, in short, for BioGraph Infiniti
animations, TTL is using Cinepac.
What type of files does BioGraph Infiniti use for recording and playing back
video?
For video recording and playback, TTL is still using Indeo. The new
tendencies for video are leaning towards using MPEG compressions.
MPEG, or MPG, is what's used for commercial video productions (VCDs
and DVDs). There are many of these MPEG formats around, MPEG I,
MPEG II, etc. They produce the best quality/compression ratios. TTL
experimented with MPG files, but had quite a bit of difficulty trying to
manipulate the playback direction (i.e. play backwards and play frame by
frame). If you want to produce AVIs for BioGraph Infiniti it is important to
note that the software totally ignores the sound track, if there is any,
because it could cause conflicts with the software’s audio feedback
functions. Also, it is best to produce short clips, because long ones take up
a lot of memory.
Can I view BioGraph 2.1 sessions in BioGraph Infiniti?
No, unfortunately old sessions cannot be read in BioGraph Infiniti. We
recommend continuing treatment with BioGraph 2.1 for clients who require
trend reporting; all others can be transferred to the new platform.
Does the new BioGraph Infiniti Software use Key Disks?
No, key numbers are used instead. Two key numbers are provided for each
license of software purchased - one key code and one application key code.
Thus you can no longer "lose your key disk" as your key number is based
on your encoder number.
How does one download the new Infiniti animations you make available on
your web page?
To download Infiniti Animations
Right Click on Animation link
Goto Save Target As…
Save animation to C:\Program Files\Thought Technology\Infiniti\AVI
You can then select the new animations for existing screens by using either
Screen Editor or Screen Editor Lite. If you are replacing an animation on a
MAR 664-00
screen, right click on the animation, and select the new animation from the
list. Make sure you substitute a similar screen (i.e. linear for linear, circular
for circular, coherence for coherence, etc) and that the animation runs in the
same direction as the animation you replaced (i.e. the flower opens as one
moves through the animation). If it doesn’t and you are using the full Screen
editor, you can change the direction by clicking on “settings” and checking
“invert animation direction”.
