I don't know how you're opening these molecules but if you're using
the "open" command then providing the "noprefs" keyword will prevent
smart display. Also, if you are using openModels.open() or
openModels.add() then there is a 'noprefs' keyword that you could
specify as False. The 'noprefs' keyword for the open command has been
around for awhile, but that keyword is new for the openModels
functions, so if your plugin needs to work with a variety of Chimera
versions either you will need to introspect the openModels function
(using Python's inspect module, probably the getargspec function) or
check chimera.version. I actually recommend the inspect approach
since the format of chimera.version has changed over time, so inspect
is more bulletproof.
Using that setAttr command for stickScale works for me. You are
aware that stickScale defaults to 1, right?
There will be some minimal speed advantage to using direct Python
calls to runCommand (elimination of some of the text parsing), but I
would only expect the difference to be noticeable if we are talking
about thousands of calls to the functions. I guess I'm referring to
the type of code you sent, where the Midas-module equivalent function
is called (so only the parsing is eliminated). There certainly could
be more savings in some cases where the generic Midas-module code is
replaced by special-purpose code.
