Hi all - By popular demand we've posted the dmri_* executables compiled on snow leopard here: ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/misc/macos-snow-leopard-intel/dmri_5.1_snow_leopard.tar.gz
This is not the entire FS distribution, just the commands that are called by trac-all. If you are a mac user with snow leopard and have been running into memory issues with the leopard version, you can download this, copy the new files into your $FREESURFER_HOME/bin, and try rerunning the part of the analysis that had errored out.
Let us know if there are any problems, a.y
