Dear Experts,
I want to illustrate the nature of a relationship found from VBM. I ran a GLM which included a questionnaire score to see where this measure was correlated with GM in the brain. I have a result, but I am unsure how to get the result out to plot it. I've seen this post here ( https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=FSL;c5ccfc57.1507 ), where fslmeants is used on the relevant cluster applied to the GM_mod_merg image, but I thought it would make more sense to use a mask (in individual subject space) on the _struc_GM.nii.gz image that is produced by VBM, and take the mean of non-zero voxels here, using fslstats.
What is the correct approach please, and could you explain why?
Thank you.
