First, create an LTA to go from the orig to rawavg space:
tkregister2 --noedit --mov orig.mgz --targ rawavg.mgz --reg deleteme.dat
--ltaout reg.orig-to-rawavg.lta --regheader
Then concatenate with the input volume lta, eg,
mri_concatenate_lta -invert2 reg.orig-to-rawavg.lta 001.lta
reg.orig-to-001.lta
Check:
tkregister2 --mov orig.mgz --targ 001.mgz --reg reg.orig-to-001.lta
The to volumes should be in registration
Then use mri_vol2vol (intensity image) or mri_label2vol (segmenation) to
resample
