Hi all,

I was wondering if somebody has experience plotting crosslink distance histograms for symmetric complexes. Specifically, since the complex I'm currently working with is symmetric, I obtain many copies of the same pseudobond for displaying on ChimeraX, each based on different atom sets.

For example:

Chain A, residue 160 - Chain A, residue 240;

Chain A, residue 160 - Chain B, residue 240;

Chain A, residue 160 - Chain C, residue 240;

...

Chain G, residue 160 - Chain H, residue 240;

Chain H, residue 160 - Chain H, residue 240;

Some of these result in exceedingly long distances that are simply not correct. I know I can set an upper threshold through the "select maximumDistance xx" command, but I am looking for a way to obtain the set of shortest crosslinks for each residue pair combination in this assembly, even though some pairs may exceed an expected distance maximum (like a 30Å cutoff for a Ca-Ca distance) for other purposes. Any help with this would be much appreciated!

Best,

Jose Gorbea
