Hi Daria, this is not something you would do with tkregister. First, you need to map the curvature from the individual subject to fsaverage_sym. You can do this for all subjects in your group with a call to mris_preproc; spec --meas curv instead of --meas thickness. Then load this as an overlay with fsverage sym and see if the curvature patterns matchup.

Hi Doug,

I've tried using tkregister2 and registering my individual subject's T1 to the fsaverage_sym but it hasn't worked. Could you point me to the correct movable volume and register.dat files that I should use? I'm not sure what they print out as.

Thank you, Daria

Hi Daria, the only way is to map the individual curvature to the group space (fsaverage_sym) and see if the curvatures seem to align. doug

ps. Please post questions to the FreeSurfer list. Thanks!

Hi Doug,

We are experimenting with adding xhemi to our processing stream. Is there is a way to QC the results at an individual subject level?

Best, Daria

Hi Daria, I would smooth the left and right separately, then compute the LI. doug

Hi Doug,

Could you please clarify when you suggest it's best to smooth if using the xhemi scripts? I'm a bit confused based on the emails below. http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg27761.html

Thank you, Daria
