[chimera-dev] opening file in extension.

[Eric Pettersen]

Hi Devin,
	Without seeing your PDB files I can’t say for sure, but if your “points” are in ATOM records all in the same residue, then Chimera is using an N-squared algorithm to try to find the connectivity between the “atoms” in your “residue".  You can circumvent this computation by putting all your points in HETATM records, and use a different residue number (combined with chain ID if necessary) for each point.

Currently, I am using the chimera.openmodels.open() to display these pdb files. This was not a problem until I started using .pdb files that consisted of hundreds of points. Because I am opening multiple .pdb files, the call to "setCategory()" does not execute fast enough and the root will have changed.
