Hi,
In order to obtain the vertices of lh.curv that belong to a specific freesurfer cortical ROI, such as 'superiortemporal', or 'superiorfrontal', etc., I use the information in lh.aparc.annot, as described for example in http://surfer.mnr.mgh.harvard.edu/fswiki/AnnotFiles/ .
However, now I am interested in looking at the principal curvatures in the same cortical ROI. To obtain the principal curvatures, I use
mris_curvature -max $SUBJECTS_DIR/caseXYZ/surf/lh.<some_surface> and mris_curvature -min $SUBJECTS_DIR/caseXYZ/surf/lh.<some_surface>
My question is, which surface should I use in <some_surface> so that I can still identify the vertices of interest using lh.aparc.annot?
In other words, how do I ensure that the output of the mris_curvature command has the surface vertices stored in the same order as lh.curv?
Any help will be much appreciated!
Thanks, Peter
