Hello all, Warren,
With the new PyMOL version, myself and others at the lab have found an issue
with ray tracing of mesh representations causing memory utilization errors.
With parameters identical to those used in previous versions of PyMOL, 1.2r1
has crashed when ray tracing isomesh generated isosurface meshes. A memory
allocation error is given, but a lack of memory does not appear to be the
real issue, as PyMOL crashes long before all RAM is consumed, and the same
error is given when we attempt to run this process on a machine with 12GB of
RAM.
There have also been a few minor issues with the fetch command. Namely,
we've seen intermitent inexplicable failure of the fetch command, while
simultaneously using it in another version of PyMOL with no issue.
Also, some older scripts now need more specific import statements to utilize
certain build-in PyMOL functionality. For example, I did not need to state
"from pymol import selector" to use the selector.process() function in other
versions of PyMOL, but this is not the case with the new version. Does this
reflect changes in the cmd API setup?
Regards,
Stuart Ballard
