Hi Ziad,
Thank you very much for your reply! The mris_convert -c didn't work so I tried:
mris_convert --annot lh.aparc_parula.a2009s.annot lh.inflated lh.aparc_parula.a2009s.annot.gii
and it worked like a charm!
One last question:
I loaded the merged hemispheres ($ suma -spec subj.both.spec) and I tired turning off the bk:Convexity by deselecting the "I" drop box on the surface controller panel. It only turned off the right hemisphere's convexity display (the same thing worked for right/left hemisphere only). Did I do something wrong or can I turn off the display via command line?
Thanks,
Xixi
