[Chimera-users] script for

[lorenzo]

Dear all,

I'm trying to write a script to interpolate between two structures and
save the intermediate conformations as pdb files.
I need a script since I have to repeat this procedure several times.

As far as importing the structures and interpolating is concerned I have
no problem:

open A.pdb
open B.pdb
morph start #0
morph interpolate #1 frames 6 (I need 5 intermediates)


What I don't manage to figure out is how to save the intermediate
configurations.

Figuring out that morph interpolate was generating a trajectory stored
as the model #2 I tried
         write format pdb trajectory #2 out.pdb
but it didn't write anything

I also unsuccessfully tried with 
         perframe write format pdb out.pdb
but I still got no output.

Does anybody have any suggestion?

Regards
                   Lorenzo Bongini
