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 file
Could 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 ___________________________________
