[Chimera-users] BIOMT symmetry matrices

[Elaine Meng]

Hi Joe,
Besides the “group biomt” option of “sym,” there is also “group #N” where N is the model number of another model.  
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/sym.html#options>

However, I believe you would need to match your structure onto model N pretty well before using that.
I hope this helps,
Elaine
