[Chimera-users] Morphing code

[Elaine Meng]

Hi MInh,
Your commands are fine the first time you use them after starting Chimera to create the morph.  The “default already defined” warning is just when you use the morph commands again before quitting from Chimera.  It is saying you already set up and created the morph and there is no need to do it again.

You could just use the first 3 commands one time (morph start, morph interpolate, morph movie) after starting Chimera and opening your input structures #0 and #1. Then save session.  Then restore session and just use the coordset commands to play the morph.  There is no need to try to create the morph trajectory #2 multiple times once it has already been created.

I hope this helps,
Elaine
