[Freesurfer] mris_twoclass

Hello,

I am trying to use mri_twoclass for the first time to do a simple comparision of means for the output from parcellate_subject(i.e. cortical thickness and cortical volume) between 2 groups. This the command line i'm using but I keep getting the following output:

mris_twoclass -o average7 lh thickness c1_emot_104 c1_emot_106:c2_emot_101 c2_emot_103 -t .01

output: using average7 as output subject mris_twoclass: must spectify ':' between class lists

location: /space/engram/6/users/emoaging/

Also is mri_twoclass better than mris_glm to use for comparing the parcellation results between 2 groups?

thanks,
