Last week, I made a patch to the 3drotate algorithm. There was a mistake in this patch, which affected 3dvolreg (which uses the same functions). The mistake would cause 3dvolreg to crash. If you downloaded AFNI source or binaries between Feb 24 and now, you should re-download.
However, at this moment, only the Linux and Mac 10.3 binaries are updated. The SGI and Solaris binaries should be fixed tomorrow (Monday, Mar 1) -- I am at home, and the machine I need to access for compiling those binaries seems to have crashed.
Sorry about this --
