By default, feat was saving analysis to the users $HOME directory on error or in case of an empty outputdir variable. We found users would often "lose" data this way causing a lot of unnecessary data to be saved. I attempted to set a default directory to tmp by editing the $FSLDIR/ etc/fslconf/feat.tcl and adding: set fmri(outputdir) "/Volumes/local/tmp/tmp_analysis" This doesn't seem to be working though. Either the setting is being overwritten somewhere or default behavior is handled elsewhere. Any ideas? -james
