[Chimera-users] Using per-frame scripts with color by attribute/bfactor

At this point the only data that Chimera supports on a per-frame
basis is atomic coordinates. So there is only one bfactor per atom,
not one bfactor per atom per frame. The only way around this that I
can think of is to not to overload the bfactor field but to instead
put your per-frame data into a series of attribute assignment files
that you would read in with the defattr command at every frame. You
could then use your rangecolor command after that (with whatever
attribute name you used in the assignment file).
I believe VMD supports per-frame data, if that is of any help.
