Are you sure those are the dimensions? They do not look right. It should be something more like ~120000x1x1x120
Try running
mri_info --dim fmcpr.up.sm5.self.lh.nii.gz

        External Email - Use Caution        

Dear freesurfer expert:
  I am sorry to disturb you. I have a question that when I use the command 'preproc-sess -s sess01 -fsd rest -stc up -surface self lhrh -mni305 -fwhm 0 -per-run -force', the dimension of output file of fmcpr.up.sm5.self.lh.nii.gz is 1*1*1*120. However, when I apply it to the fsaverage. It has correct dimensions. Could you tell me why it happens?

  Thank you

  Mingyang Xia
