That scales the coordinates and will have no effect on the file size. Try mris_decimate instead. Note that the version 6 mris_decimate is not deterministic. I've put a deterministic one here https://gate.nmr.mgh.harvard.edu/safelinks/greve/mris_decimate On 9/4/19 2:49 PM, roc...@netzero.net wrot

I'm not sure you can. Unless you have multiple samples, you can't compute a variance. If you can't compute a vvariance, then  you can't compute a significance. Maybe you can do some kind of bootstrapping On 9/3/19 1:49 PM, Matthieu Vanhoutte wrote: > External Email - Use Caution > > So
