Hello, I'm currently doing a resting state functional connectivity analysis. I have two groups and my ultimate goal is to compare the resting state network of group 1 to that of group 2.
What is the standard procedure for comparing resting state connectivity across groups? I've followed the directions on the FsFast Functional Connectivity Walkthrough (http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastFunctionalConnectivityWalkthrough) and after the isxconcat-sess, I did mri_glmfit --y ces.nii.gz -wls pcc.nii.gz -surface fsaverage lh -glmdir [my/group1.directory.wls} -nii.gz, for each group. This got me the mean for both groups individually. I'm now stuck on how to proceed to compare across my groups. Using mri_glmfit creates the problem of trying to pre-process each group without a variable for -measure, and I'm not sure if using the -iv flag with the ces.nii.gz or pcc.nii.gz is going to give me what I need.
