Hi FreeSurfers. Is it possible to regress functional data against a continuous variable in the volume? I’m analyzing a reward processing study that activates sub-cortical and cortical regions, and I’d like to regress those data against a continuous measure of depressive symptoms administered to each participant. I understand the basic fsgd/mri_glmfit approach from the FS tutorial, but I want to stay in the volume in order to examine sub-cortical structures (e.g., nucleus accumbens). Is this possible?

Thanks!
