Hi Xavier-
To show ligands coming into a protein binding site I generally use some sort of
morphing approach rather than translating the ligand. The reason is that
slerpy, even if it could cope with translate, would not interpolate the ligand
position from one view to the next so you'll end up with sudden jerky movements
of the ligand.
On the other hand, if you generate a multistate model using morphing (either
lsqman, rigimol, or http://www.molmovdb.org/molmovdb/morph/) then you can use
smorph in slerpy to incorporate the morph into your movie. See also
http://ginsberg.med.virginia.edu/~dcoop/Help/morph.html for hints on setting up
a morph.
I've been working on a slerpy demo page that includes some morphing but it's
not done yet.
I've never tried using the translate command in a slerpy action. I'll have a
look at that tonight.
Thanks,
Joel

Hello all ! I am trying to use Slerpy to make a movie and I get some trouble. I
would like to show a ligand coming and binding to my protein* So, following
the Slerpy instructions, I stored all my orientations then I tried to apply
actions to the different views. But when I typed this command: sgo 2
saction translate [0,20,0], ligand I got the following error:
Error: too many arguments for add_action_current; 1 expected, 2 found.Usage:
add_action_current cmd I have an object named ligand in Pymol and the
command translate [0,20,0], ligand works pretty well in Pymol (without using
Slerpy)*Does anyone know how to solve the problem? Thanks! Xavier. Xavier
