Hi list, I need to project functional volume data to surface with GIFTI (.gii) format, does anyone has experience to do that?
Here is what I did: 1) mri_vol2surf --mov func.nii.gz --reg bbregister.dat --trgsubject fsaverage --interp trilin --projfrac 0.5 --hemi ?h --o func_on_fsaverage.?h.nii.gz --noreshape --cortex 2) mri_convert func_on_fsaverage.?h.nii.gz func_on_fsaverage.?h.gii Command (1) worked, however, ERROR "freadFloat: freed failed" during command (2). Then I tried another way (convert to paint file first, then use caret) like this: 3) mri_vol2surf --mov func.nii.gz --reg bbregister.dat --trgsubject fsaverage --interp trilin --projfrac 0.5 --hemi ?h --o func_on_fsaverage.?h.w --out_type paint --noreshape --cortex ERROR: LabelMarkSurface: label point 148835 exceeds vertices 146238 I am confused because command (1) worked very well, I can load the data in MATLAB, or freeview. Any help is appreciated! Ting
