Dear guys,

I checked one of my subjects file /stats/lh.aparc.stats, in which it said the commandline as:

mris_anatomical_stats -th3 -mgz -cortex ../label/lh.cortex.label -f ../stats/lh.aparc.stats -b -a ../label/lh.aparc.annot -c ../label/aparc.annot.ctab subject1 lh white

what does the flag "-th3" mean? I'm using Freesurfer v6.0 beta.

Thanks, Kaiming

Dear Douglas,

I saw the previous tutorials didn't include this "-th3" flag, is there any difference between the following two command lines?

mris_anatomical_stats -th3 -mgz -cortex ../label/lh.cortex.label -f ../stats/lh.aparc.stats -b -a ../label/lh.aparc.annot -c ../label/aparc.annot.ctab subject1 lh white

mris_anatomical_stats -mgz -cortex ../label/lh.cortex.label -f ../stats/lh.aparc.stats -b -a ../label/lh.aparc.annot -c ../label/aparc.annot.ctab subject1 lh white

Thanks, Kaiming
