Dear Freesurfer experts,
I am going to do convert the preprocessed surface functional data to volume in
fsaverage space so that I can used the processed data in SPM for further
analysis, saying, beta series analysis. Because the trial nubmer is not same
for each subject in my experiment, I think freesurfer can not deal with this
condition (please tell me if I am wrong). I tried mri_surf2vol, it worked. But
it is time consuming. It takes around 5 minutes per 10 volumes. In addition,
the result volume is too big (67MB/ volume for 256*256*256 matrix, 1mm
resolution). The code is as follows:
mri_surf2vol --o ${Dir_Subj_fMRI}/$isub/bold/${irun}/Ribbon/${iVolume}
--subject fsaverage --so ${SUBJECTS_DIR}/fsaverage/surf/lh.white
${Dir_Subj_fMRI}/$isub/bold/${irun}/LH/${iVolume} --so
${SUBJECTS_DIR}/fsaverage/surf/rh.white
${Dir_Subj_fMRI}/$isub/bold/${irun}/RH/${iVolume}
Are there better ways to accomplish my goal?
Best,
Zhiwei _______________________________________________
