I am trying to register an anatomical ROI (V1Left.nii.gz) in the same volume space as brain.mgz for SubjectX using spherical registration to the average subject brain. I have used the following command
mris_preproc --s SubjectX --out ~/SubjectX/lh.ave.v1.mgz --target average --hemi lh --ivp ~/SubjectX/V1Left.nii.gz ~/SubjectX/mri/ transforms/identity.xfm
and received this output:
nsubjects = 4 ERROR: number of input volumes (1) does not equal number of subjects
From where does the code read nsubjects = 4?
Thanks for the help,
Holly Bridge
If required, identity.xfm contains the following
MNI Transform File % tkregister2
