New subject: Repost ERROR mri_volcluster

14 Feb 2012


      Dear Doug,
Can I run the mri_volcluter without --reg ?
I am asking this because when I run:
mri_glmfit-sim \
      --glmdir GroupAnalysis_ADC.glmdir \
      --grf 3 neg \
      --cwpvalthresh .05 \
      --overwrite
gives me the following error (I also attached the log file):
Also, does neg means now that Class1 (=controls)< Class2 (=Patients) for my MD values?
Many thanks.
Antonella
