Hi Joe, I changed the sym command translation symmetry in Chimera daily builds (1.6) so you use sym #0 group shift,5,280 while in Chimera 1.5.3 you would use sym #0 group t,5,280 The reason for the change is that the sym command now handles tetrahedral symmetry using "group t". This of course is annoying. So I've changed the Chimera daily build so it will produce the shifted copies using "group t,5,280" and will only produce tetrahedral symmetry if there are fewer than 2 arguments after the "t". The "group shift,5,280" syntax still works. So tonight's Chimera daily build will be backward compatible with the Chimera 1.5.3 production version. Tom
Hi,
I found an online post about how to use the sym command to duplicate models. The post is here: http://plato.cgl.ucsf.edu/pipermail/chimera-users/2011-June/006433.html The commands in the post are:
open 1ei3 sym #0 group t,5,280 axis 1,0,.4 coord #0 surf true
I got an error of "Invalid symmetry group syntax "t,5,280"" from the sym command. The versions that I have are daily build Oct 18 on Mac, and Oct 13 on Windows.
Thanks, Joe
