[Chimera-users] Rotation along symmetry axys

[Elaine Meng]

Hi Leonardo,
If I understand correctly, I think you can use the "models" option (e.g. "model #2") of the "turn" command or other movement commands like "roll" and "move" to move only the specific model instead of the whole scene.  The axis specification in the command also allows you to control the orientation of the rotation:

However, if it is a map and you want to save it in the new position, you would have to resample it first.  Resampling to create a new map is necessary since the original map would just show up in its old position if you save and reopen without resampling.  This issue is discussed in the bottom part of this page:

I hope this helps,
Elaine

I would like to rotate the map 90 degree in the z axys, so that Z axys now separate the molecule in a C2 pseudosymmetry, in order to play with some symmetry relaxation features to refine differences in the two map vortexes.
