I think it may be our fcseed-config command line fcseed-config -segid 1 -seg $SUBJECTS_DIR/Subj/mri/MRS_MASK.mgz -fsd rest -mean -cfg MRS_MASK.config –overwrite
It should be -seg MRS_MASK.mgz
They way you have it, fcseed will use the segmentation for Subj for all subjects, which is why it works for one and not for others

Hi list,
I'm having problem to use FS-FAST fMRI connectivity using as seed a mask of a MRS voxel or .label obtained by drawing it from surface. In order to resolve my concern, I'm reporting step by step the command lines which I have used. The mask, f.nii.gz, orig.nii.gz and aparc+aseg.nii.gz showed a good overlap.
These are the features of each one:

When I run fcseed-sess -s Subj -cfg MRS_MASK.config -overwrite, it seem to be functioning for the first subj, but the next subj2 show this error
