Hi Batsal, I am not sure I understand the question. You can save PDB files or Mol2 files as described in http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/savemodel.html These are the only formats currently available for writing out molecular coordinates. Currently there is no way to save MD trajectories in any of the other MD formats, only as PDB (after playing all of the frames you want to save, choose File... Save PDB or one of the other methods described in the man page above and use the setting to Save "all frames"). I am not sure what you mean by "Chimera format" - there isn't really a Chimera format for molecular structure, unless you mean a session file, or perhaps a PDB file written by Chimera. Why not use the original MD format in the MD program? I am not sure why you want to put the data through Chimera before going back to the MD program. I hope this helps, Elaine ----- Elaine C.

Hi,

Is it possible to save the pdb file in the same format as we loaded into Chimera? This is because the MD program that I am using does not recognize Chimera format.

Any help will be appreciated.
