[chimerax-users] How to align two molecules using a subset of atoms in ChimeraX?

[Steve Chou]

Dear ChimeraX support team,
I tried the following command first - it worked well.
==================
match #1/A to #2/A
==================
Then I tried to align the two molecules using parts of them - it didn't
work and complained that "No chains in reference structure PROT.pdb #2
compatible with BLOSUM-62 similarity matrix."
==================
matchmaker #1/A:10-20 at CA to #2/B:10-20 at CA
==================
System Info:
==================

Platform: Linux-3.10.0-862.el7.x86_64-x86_64-with-redhat-7.5-Maipo
ChimeraX version: 0.9 (2019-02-05)
==================
Thank a bunch!
Steven
