Dear all,
I have a series of .vtk files in MNI152 1mm space from an external thalamus atlas outlining specific thalamic nuclei. I would like to put these into native subject space and calculate the volume from each nuclei.
I would imagine that I would do the following:
1. run mni152reg --s --1 on each subject
2. mri_vol2vol --mov mni152space_atlas_file.nii.gz -- targ subject/mri/orig.mgz --reg subject/mri/mni152.orig.mgz.reg --inv --o newoutputfile_subject_space
But then I am not certain how to calculate the volume of the new output file.
