[Freesurfer] Intersection of labels with other labels or volumes

Hello- Is there a simple way to obtain the intersection of two labels, output into a third label? Or the intersection of a label and an .mgh file output by mri_surfcluster? For instance, I have a cluster defined by mri_glmfit/mri_surfcluster that spans multiple anatomical regions, and I want to

Nathan, The significance values displayed are -log10(p), which is easier to remember this way: a value of '2' (as displayed for a vertex in qdec) is p=0.01, a value of '3' is p=0.001, etc. Nick On Thu, 2009-08-27 at 11:29 -0400, Dankner, Nathan (NIH/NIMH) [F] wrote: > Hi all, > > I've read in

Hi all, I've read in the wiki that the heatmap display in qdec is a -log10(p). What is the stat behind this when determining whether the average thickness differs between two groups? Is it a t? ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.

yes, I think it will probably help a bit for mprage scans. Essentially it changes the default assumptions about noise and contrast characteristics (it assumes more of both) and will help the intensity normalization get a bit further out the thin white matter strands. Try it and see what you thi

Hi,everyone. The debug output is followed. I think the problem is "$MLF | ${MATLAB} -display iconic -nojvm -nosplash" cat /tmp/mos_12142_.m /usr/local/bin/matlab -display iconic -nojvm -nosplash this command is not implemented rightly. However, when I run only the matlab cmd, it's seem to be right.

no, it's more agnostic. Optimized for both spgr and mprage (or neither, depending on your perspective). You're probably right that mp-rage is more common these days, but I think spgrs are still fairly widespread on GE. On Thu, 27 Aug 2009, Michael Harms wrote: > > So, are you saying that the de

So, are you saying that the default recon-all stream is really optimized for SPGR, and anyone running a MPRAGE should be including the -mprage flag when they run recon-all? If so, this is news to me, and I suspect many other FS users. The default recon-all setting is "set IsMPRAGE = 0", but I su
