hello again!
first i have to thank rick for all the help with my afni_proc.py code. after the pre-processsing and first step i have to do group analysis now. here are some of my questions!

I. i set 7 conditions in afni_proc.py by the "-regress_stim_labels", which are "M1, M6, N1, N6, W1, W6, A", and i set 7 kinds of "-gltsym", which were labeled as 1-7, to make next steps more convenient, but i can't see the files from which i can find signs of these conditions or contrasts except the ideal_M1.1D, ideal_M2.1D etc. i know that in fact all these conditions or contrasts are included in the files. could you please tell me how to set the data of one condition in group analysis code?

II. i checked the pdfs in afni-handouts of group analysis, and i found that the 3dMVM suitable for my experiment. my experiment is a 2(gender: M, F)*4(M1, M6, W6, A), and perhaps i want age as an co-variate is 3dMVM a better choice? (but i can't find the 3dMVM in "program help" page in the afni website(i can learn it by "3DMVM -help" but i prefer on web page, so if you don't want to add that to your website, that's totally fine.).)

sincerely
Yuan
