If you just want to resample the ROI to the average subject, then use mri_vol2surf, something like
mri_vol2surf --mov V1.nii --regheader --s SubjectX --hemi lh --projfrac 0.5 --trgsubject fsaverage --o lh.v1.fsa.mgh
syntax might not be exactly right, check the help

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,

If required, identity.xfm contains the following
MNI Transform File % tkregister2
Transform_Type = Linear; Linear_Transform = 1.00000000 0.00000000 0.00000000 0.00000000 0.00000000 1.00000000 0.00000000 0.00000000 0.00000000 0.00000000 1.00000000 0.00000000 ;
