Hi Vladyslav, In Chimera you can select part of the structure and then save only the selected atoms (it is an option in the File… Save PDB dialog), but it will stil be PDB format. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/savemodel.html#pdb> Chimera does not convert PDB to XYZ format, so you would need to find some other program to do that part -- maybe openbabel?

Greetings. Could you possibly help me with cobverting of pdb to xyz? I need to select a part of a molecule, "cut it out", and write coordinates of this part into xyz file. Is it possible? How to do that?

Thank you for your reply in advance

Best regards, Vladyslav Dziubz
