Doug,
Thank you very much for your quick response. Following your advice, I deleted 
the previous "average"subject and created a new "average" subject. But now the 
Error is the same as it was for "fsaverage".
When using the command line:
mri_surf2surf  --hemi lh \ 
--s average \ ...

or 

mri_surf2surf --hemi lh \
--s fsaverage \ ...

ERROR: Option  --s unknown

instead of "--s" I also tryed other command lines: --srcsubject average

I am using FS version:
centos4-stable-pub-v4.0.5-full

Thank you for your help.
Sincerely,
Alex.

Betreff: Re: [Freesurfer] mri_surf2surf - Error

 did you create a subject called "average"? This is done with
make_average_subject. Alternatively, we distribute an average subject
called fsaverage, so you can just use that instead if you want.

Dear
Freesurfer Users,
We have a little problem with mri_surf2surf. Our goal is to
determine
the statistical data - t-test, ANOVA, for a group of subjects. So
initially we
made the recon-all, autorecon1,2,3 and -qcache for all subjects. After
that we
created the FSGD file and mris_preproc - in order to create ?h.thickness.mgh 
file. Now in order to initiate the  mri_glmfit step we have to
create the ?h.thickness.sm10..mgh file with the mri_surf2surf command.

We used this command line:
mri_surf2surf --hemi lh \
 --s average \
 --sval lh.thickness.mgh \
 --fwhm 10 \
 --tval lh.thickness.sm10.mgh

and we receive the Error:
– /usr/local/freesurfer/ subjects/average/surf/lh. sphere..reg – could not open 
fileCould you please tell us where might be the mistake ? What step is needed 
to create the lh.sphere.reg file. Thank you very much for your help.

Best regards,
Dr. Alexandru Hanganu
