Hi Maedeh
the surface file should be the one that defines the common coordinate
system (usually sphere.reg) and the annotation should refer to a file in
the subject's label dir. Every subject in your list must have both files.

Dear Dr.Bruce Fischl
Thank you very much for your great sense of responsibility.
Sure, i have sent you a zip file named "Maedeh_results"(it was a rather big
sized one so i had to
send it through Wetranser). Hope you have received it.
However, a general question is that, according to freesurfer help the required
arguments for
"mris_ca_train" are :
mris_ca_train [options] <hemi> <canon surf> <annot file> <subject 1> <subject 2> ...
<output file>
as it seems it gets one surf file(e.g sphere.reg),and one annotation file, but
several subjects...so
what does this surface file refer to?should i make an average of all subjects'
.reg files? and also
for the annotation file ! just one .annot is enough or i have to make an
average of several
annotation files?
if yes, how should i do that?
i would be grateful if you could help me.
Best regards
Maedeh,
