wmparc in T1w space

[tashrifbillah]

A few notes:

• For HCP data: T1w resolution is 0.8mm3 brain.mgz resolution is always 1mm3

  So brain is the FreeSurfer space different from T1w space.

• mri_vol2vol is the command for registering a given image to FreeSurfer space.

• I am guessing this is the T1w-->brain.mgz transform file reported by mri_info brain.mgz​ command:

  talairach xfm : fs7.1.0/mri/transforms/talairach.xfm

  Edit: My guess may not be right

  But I do not see an inverse transform. So for future work of wmparc-->T1w, we shall have to figure out that inverse transform.

  Edit: mri_vol2vol --inv should transform brain-->T1w i.e. wmparc-->T1w

Feature request by @yrathi for future.

Hi @yrathi , we have solved this problem here in the past.
