Dear all,
I would like to know if while doing a group analysis for my FA data and I do the correction by multiple comparisons for the clusters:
mri_glmfit-sim \ --glmdir Group_Analysis.glmdir \ --grf 3 neg \ --cwpvalthresh .05 \ --overwrite
what exactly is defined the cwpvalthresh. I mean I know that this is a cluster-wise p-value threshold but is this calculated from or based on the FA intensity values?
Thank you very much for your clarification. Antonella
