[Chimera-users] Pseudobonds disappearing during morphing movie

Hi there - i'm scripting a complex movie and am having problems with
pseudobonds during morphing.  Script is pasted at the end.

Part of the movie contains a morph between two structures, both of
which are missing the same amino acid segment.  Loading the two
structures show the pseudobond for the missing residues and the
resulting morph also contains the same pseudobond.

I've been changing the thickness of the pseudobond with :

setattr g lineWidth 8

and while the two static structures and the morph in the chimera
window have a thicker pseudobond, the resulting movie (encoded to
.mov) does not.  Am i doing something wrong?


p.s. incidentally, when morphing by script, if one includes "nogui
true" with the "morph movie" command, pseudobonds aren't kept in the
morph at all.  A bug?
p.p.s. can someone explain to me the difference between "setattr g"
and "setattr p"?  I've read the manual but i don't understand why only
the former seems to work for me.
