[Chimera-users] Atom Specification not working in exported PDB

[Gustaf Olsson]

Hello again Chimera Users

So now that I have the “movie” command working decently, it turns out that I cannot export a PDB file from my MD simulation and retain the ability to select by residue or atom number.

PDB files generated by other software (PACKMOL, AMBER) works fine though when I exported a PDB file from a fram in an AMBER MD simulation using chimera, I can open the file, I can select using residue names though trying to refer to atom or molecule numbers does not work. To be clear, the exported PDB file contains multiple molecules and solvent, all ar present and the file loads though trying to run commands like

   show :17
   ~show @536-593

Affects EVERY atom and molecule in the system when it should only affect residue 17 (by specifying residue number OR all atoms in that residue). Using the

   show :XXX

works as intended though this affects all residues XXX and I only want to affect residue 17.

Am I doing something wrong or can I solve this in a simple way?

Best regards
