Jay,
The only Brain Voyager file format we read at this time is the
Surface File format.
This web site describes the BrainVoyager formats: http://
www.brainvoyager.com/BV2000OnlineHelp/BrainVoyagerWebHelp/
mergedProjects/FileFormats/whskin_homepage.htm
The VMR file looks fairly simple to read and the FMR looks more
complicated as it references STC files that appear to be like VMR
files. Are there any options in your version of BrainVoyager to
export to non-BrainVoyager formats such as Analyze of NIFTI?
Modification of Caret to read these files is possible, but this is
probably something you, myself, and David should discuss.
If there are other Caret user's who would find import of these
BrainVoyager files into Caret useful, please let us know.
It may be possible to use AFNI's "to3d" program to convert the files
to AFNI format, but "to3D" is not a tool that I know how to use.

Hi Everyone,
I'm BrainVoyager user (on a Windows 2000 machine), and a
total newcomer to Caret. I have a general question about how best
to port my functional and anatomical data into Caret.
Here's my overall situation: My study is revealing a pretty
larger number (>40) of highly reliable foci all over the cortex,
and I'd like to map them to a good surface-based atlas so as to (a)
assign them to Broadmann area/s, and (b) compare them reliably to
previous reports of activation, so as to discern the potential
functional significance of these foci. It looks like Caret is
right for the job.
Since Caret expects the volume data in a non-Brainvoyager
format (e.g., AFNI, SMP, etc), I need to decide whether to (a)
start over with my raw DICOM files in AFNI/SPM etc and process them
until they're ready for Caret, or (b) use my existing BrainVoyager-
format files (*.vmr, *.fmr etc) and find some way of converting
them into a format that Caret accepts.
So does anyone know which (if either) of the above
strategies is workable? I figure there must be some Caret users
out there who have grappled with this problem. Any advice you can
provide would be useful.
Thank you very much in advance,
