Dear list,
I would like to rotate my orig.mgz volume into chiasmato-commissural space to assess the length of a freesurfer-obtained hippocampal segmentation along the main axis of the hippocampus. I am doing this to enable use of a slice-counting method.
Now, I know that tkregister2 allows me to both rotate volumes and load aseg files, but I can only rotate the movable volume. I'm not clear on how I would set this up a) to rotate my target image in native / subject space (orig.mgz), so as not to disturb the raw length values; or b) to rotate the aseg segmentation along with it.
Is anyone able to offer any suggestions on how I might be able to use freesurfer to accomplish this task (or whether there is a different approach that would be simpler)?
Thanks in advance for any help.
Cheers, Jordan
