Hi John what parts of the basal ganglia do you want? We label caudate/putamen/pallidum/accumbens separately. You can combine them all together and get one ROI if you want. They should all be in the wmparc.mgz cheers Bruce On Mon, 21 Sep 2015, John Anderson wrote: Hi Experts, I want to do

--grf is gaussian random fields for the volume (not surface). Re: --2spaces, your understanding is correct. FDR: you can do it in matlab, something like sig = MRIread('sig.mgh'); p = 10.^-abs(sig.vol) pthresh = fast_fdrthresh(p,fdr); ind = find(p < pthresh); sig.vol(ind) = 0;

Yes, it is addressing that question. The contrast should be the same as your Group Diff below. Although I'm not sure you're using the proper design. It looks like you are using Sex as a continuous covariate? That is not correct. It should be discrete. So you should have 4 classes (HC-M, HC-F,

Once you have covariates you need to decide what "percent difference" means. Do you want to include the covariates? If so, then you'd use 1 0 0 0 and 0 1 0 0 (although see my warning in my previous email about using gender as a continuous covariate). On 09/19/2015 05:55 AM, pablo najt wrote: >
