Hi, I have a problem of group analysis with QDEC. Now, I want to analysis a group with one factor and three levels. When I run QDEC with this group, the terminal shows error with too many levels. So, how can I do to analysis this group with one factor and three levels? Would you tell me what to do? If not, would you suggest me any other way to get the group analysis?
Thank you in advance!

unfortunately, you've reached a limitation of qdec. it only supports two-levels in a group at the moment. you can conduct an analysis by creating the files manually. see this tutorial:

You will have to do it with the "command-line stream". Ie, set up your own FSGD file with classes and covariates, run mris_preproc, create your own contrasts, then run mri_glmfit. There are examples on the wiki.
