Hi,
I have a couple of specific questions about mri_glmfit that I could not quite find the answers to in the tutorials or message boards.
1. How would I run mri_glmfit in a custom ROI (or set of ROIs) and then correct for multiple comparisons? I have found information on how to use the freesurfer predefined labels but not a custom regions. Just for some background, I have a set of 50 regions that make up our network of interest and I would like to limit the glm to these regions. 2. How do I extract and use the results from a whole-brain glm, above a specified corrected threshold, and use those in subsequent analyses? I am doing a whole-brain, between groups analysis and then trying to use the significant results from that in within-subjects analyses.
Thank you very much for your time, Brady
