It must be that one of the ces files has multiple frames. Try running mri_info --nframes ces.nii.gz on all of the ces files to see how many frames are in each

can you send the terminal output?

Hi FreeSurfer users, I'm trying to use mri-preproc to do a group fMRI analysis(based on the tutorial). However, I keep getting an error that the number of input volumes does not equal number of subjects. It seems one volume is counted as 4 subjects. I'm wondering what the command determines to be the subject list when you use the --iv flag. For reference, I'm basing it off of this command: mris_preproc --target fsaverage --hemi lh \ --iv fbirn-101/ces.nii fbirn-101/bb.register.lta \ --iv fbirn-103/ces.nii fbirn-103/bb.register.lta \ --iv fbirn-104/ces.nii fbirn-104/bb.register.lta \ --iv fbirn-105/ces.nii fbirn-105/bb.register.lta \ --iv fbirn-106/ces.nii fbirn-106/bb.register.lta \ --projfrac 0.5 \ --out lh.ces.mgh Thanks!
