Hi Ryan,

Looks like you morphed 2 structures then showed a surface and it gave a bunch of NaN (not-a-number) errors. This happened because some atoms in the morph had NaN values. I never saw the ChimeraX morph code produce NaN atom coordinates. You could try it with ChimeraX 1.4 (you are using version 1.2.5). Or if you sent me the two PDB files I could see if I get the error, that would allow me to fix it. If you send the PDB files and they need to be kept private then send them directly to me (goddard@…) instead of replying directly to this bug report email.

Thanks for sending me your PDB files. I get the same error in ChimeraX 1.4 and I am looking into what is going wrong in the morph code to produce the NaN atom coordinates.

Resolution: → fixed

Fixed in tomorrow's ChimeraX daily build.

The morph code incorrectly calculated dihedral angle residue interpolation using the unpaired atoms and that used uninitialized atom coordinate value leading to NaN atom coordinates in the result. I fixed the code to make sure the dihedral angle interpolating only uses the paired atoms.

Thank you so much Tom! I will download the daily build and see what happens!
