Hi Chun-Chia,
I don't know what to make of the Leopard and Xquartz problem. Freezing problems are hard to sort out and usually come from X and not from SUMA...
Regarding @SUMA_AlignToExperiment, I had one space character too many. Any version postdating this message will have the fix in it.
If you want to fix the version on your computer at the moment, just remove the blank space, after the character '\' at the end of line 410.
cheers,
ziad
