Log chain table with RMSD for AlphaFold multimer predictions

[goddard@…]

The following bug report has been submitted:
Platform:        macOS-12.6-x86_64-i386-64bit
ChimeraX Version: 1.6.dev202211082330 (2022-11-08 23:30:49 UTC)
Description
Make AlphaFold prediction of multimers log a chain table that reports the RMSD and number of observed residues for each chain when an experimental structure is specified for the prediction.  Currently the alphafold logging code does not handle multimer predictions.  It aligns the longest chain to an experimental structure, so it does not compute the RMSD for other chains.  The logging code currently only handles single chain alphafold models.
