1-sample t-test with 3dMVM and fatcat

Hi Gang and Paul,
I want to compare connectivity matrices (.netcc files with 106 ROIs in each) between a single patient and a group of healthy controls, simply like in a more typical situation of voxel-wise 1-sample t-test with “3dttest -base1_dset”. I could have done this with 3dttest by “dumping” the .netcc files into some 1D files; but since I have never used the “FAT MVM” tools before, I would like to try these tools first. My preparations with fat_mvm_prep.py and fat_mvm_scripter.py went successfully. The execution of “tcsh PREFIX_scri.tcsh” was initially stumbled on the issue of “Argument list too long” as previously discussed here (https://afni.nimh.nih.gov/afni/community/board/read.php?1,158457,158457#msg-158457), but I have bypassed this issue by “ulimit -s 65536” as suggested here (https://unix.stackexchange.com/questions/45583/argument-list-too-long-how-do-i-deal-with-it-without-changing-my-command). However, when 3dMVM was finally running for a few minutes, it threw out a simple error message of “Error parsing arguments. See 3dMVM -help for details”. Could you please point me to the right direction on trouble shooting this error?

Thanks a lot for your help!
