Hi Linda, your mri_vol2surf cmd should be something like

mri_vol2surf --mov functional.nii.gz --reg register.dat --hemi lh --o lh.functional.nii.gz

I removed the --regheader and replaced the arg to --o with a file name

Hi all,

I'm trying to project volume BOLD time series to native surface in some subjects. First, I registered the functional data to orig.mgz, using:

bbregister --s subj --mov func.nii.gz --reg register.dat --init-fsl --bold --o output.nii.gz

The results look good in tkregister2. Then, I want to go from volume to surf, doing:

mri_vol2surf --mov functional.nii.gz --reg register.dat --regheader nmr00524_FS --hemi lh --o /folder/

However, it gives this error message:

Done reading source surface Mapping Source Volume onto Source Subject Surface 1 0 0 0 using old Done mapping volume to surface Number of source voxels hit = 26361 Writing to /folder/ Dim: 132698 1 1 non-standard value for imnr1 (1, usually 256) in volume structure non-standard value for type (3, usually 0) in volume structure non-standard value for width (132698, usually 256) in volume structure non-standard value for height (1, usually 256) in volume structure

I should probably use mri_vol2vol first, but which target volume should I then use? Or is there something else I'm doing wrong?

Thanks for your help!
