Thanks Satra, very helpful.

hi martin,

if you had one region you can use mri_segstats to extract for each voxel in that roi, but not for multiple rois.

here is a snippet i use for timecourses in each roi.

Hi,

I have fMRI data which has been co-registered with the FS reconstruction
using "bbregister". I would like to extract the voxel time series for
the voxels in the subcortical labels from the "aseg" subcortical
segmentation. I know that "mri_segstats" can be used with the "--avgwf"
option to extract an average time series for each label, but is there a
way to extract a time series for each voxel inside each label without
averaging?

Thanks,

Martin
