Dear all,
I need to extract three surfaces from MRI data:
- GM-WM interface -> thus, lh.white and rh.white would be the answer. - Pial interface -> thus, lh.pial + rh.pial - CSF surface
For CSF, as far as I know, the best option would be to generate a binary volume merging the appropriate labels from aseg.mgz. Then use mri_mc to obtain the surface, right?
For white and pial I guess the best option would be to use the recon-all outcome, but I have two questions: * Is there any mean to merge both hemispheres? I've tried several methods but I get trouble with the consistency of the cells... the points are aggregated, but no work is done to merge cells and remove points. * What are the differences between the recon-all outcome (lh.pial,rh.pial,lh.white,rh.white) with respect obtaining masks from aseg.mgz and then mri_mc?
Thank you so much
Best regards, Oscar Esteban
