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
