[Chimera-users] saving coordinates from a session and re-opening them in another one

[Elaine Meng]

Hi Boaz,
I believe the saved PDB file includes all the selected and displayed atoms in their correct locations from your session, but the bonds are messed up.   That is a bug and the main problem.  

selected and displayed in session: 2 models, 52 residues, 377 atoms, 361 bonds

contents of PDB file: 2 models 52 residues, 377 atoms, 381 bonds (and some of those bonds are wrong)

Also contributing to the confusion is that the default initial display tries to simplify structures to ribbons and does not show all the atoms.  To see all the atoms, hide ribbon, display all atoms/bonds (for example, commands: ~ribb; disp ).

If I simply remove all the CONECT records from the PDB file, it is fine (file no-conect.pdb is attached).  You just need to display all atoms as mentioned above.

It is OK to attach files to a chimera-users message as you did, but usually the better way to report problems to the developers is to use "Help... Report a Bug" in the Chimera menu, which will automatically include information about your computer and what version you are using.  It also allows attaching data and including your email address if you wish a response.

One of will file this problem soon and include you on the notification list.
Best,
Elaine

When I open them in the new session they look strange. Also, the saved coordinates don’t always contain the full set of displayed coordinates (I’ve done this several times on different structures and it seems particularly but not just on pdb’s with aniso card). I’m attaching the session whose coordinates I saved + the saved coordinates (I hope that’s OK with the BB policy). Please help me figure out the problem.
