External Email - Use Caution
Dear Freesurfer experts,
I am currently trying to use mri_vol2surf on my bold data. I typed this
commandline :
"
mri_vol2surf --mov
${dir1}/${subject}/${subject}${scan}_space-MNI152NLin2009cAsym_desc-smoothAROMAnonaggr_bold.nii.gz
\
--mni152reg \
--projfrac-avg 0.2 0.8 0.1 \
--trgsubject fsaverage5 \
--interp nearest \
--hemi ${hemi} \
--surf-fwhm 6.0 --cortex --noreshape \
--o ${dir1}/${subject}/${subject}${scan}.fsa5.${hemi}.mgz
"
However, when trying to run it, I obtain the following error: ERROR: could
not read .. as type 24

I also copied the output from mri_info on my bold image in .nii.gz format:
