Group level analyses trouble-shooting

Hello!

I just ran some group level analyses. Some of them look totally normal, but certain conditions look like this.

Has anyone seen this before? We were planning on going through the data from all the subjects for the conditions that look like this, and see if any particular person has a messed up run.

Any guidance at all would be appreciated! :slight_smile:

Howdy-

Goooootttttta have some details to try to even start to think about addressing the glimmer of an idea as to approach this question.

For starters:

  • how many subjects
  • what kind of processing (afni_proc.py command used would be awesome)
  • what group analysis are you running? (again, the exact command would be useful, if not necessary).

Hello!

Thank you for your patience! I’m sorry I didn’t include all of the relevant info, but here is some additional information:

  • We see this issue in all three of our subject groups: one is 28ish, the other is 40ish, and so the third total sample has around 68 subjects

  • We are using 3dMVM

  • I have attached the majority of one of our scripts below:
    (Also note that we have identical scripts for other conditions that worked great and did not give us this rainbow confetti, hence our wanting to go through the Individual Level data from all the subjects for the conditions that look like this to see if any particular person has a messed up run)
