Do you only have one subject in your input file? You need to run mris_preproc separately for each subject, create a different file for each, then mri_concat the files together On 11/9/17 6:20 PM, lanbo Wang wrote: Dr. Douglas, I try #3 method, when I run mri_glmfit, get error. The code I use

which method are you trying to implement? If #3, then you need to run mris_preproc separately for each subject, and then run that fscalc command On 11/07/2017 11:33 AM, lanbo Wang wrote: > Hi Douglas, > > Thanks for your reply. > I created the fsgd file as you show me, and run code like this. Am

Hi Douglas, Thanks for your reply. I created the fsgd file as you show me, and run code like this. Am I right? 1. mris_preproc --fsgd Subject.xhemi.dat \ --target fsaverage_sym --hemi lh \ --xhemi --paired-diff \ --srcsurfreg fsaverage_sym.sphere.reg \ --meas thickness \ --out lh.lh-rh.t

Dear experts, I have two questions about hemisphere analysis: 1) When I run left-right hemisphere paired t-test, can I add age as covariate? If use fsgd to add covariate, to this paired t-test analysis, how to make the fsgd table? 2) I want to reorganize the hemisphere from left-right to symptom-
