[Chimera-users] Make a new pdb model from a part of pdb file

[Elaine Meng]

Hi Jianhao,
Just delete the residues you don't want.  E.g. if  the residues are numbered 1-1000 and you don't want 501-1000, then command:

delete :501-1000.a

... of course, you can use any command-line atom specification, e.g. selecting that part and then

delete sel

<https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/frameatom_spec.html>

If you wanted it as a file, then just save a PDB file after you do the deletion.  E.g. menu File... Save PDB, or command "write":
<https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/savemodel.html#pdb>
<https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/write.html>

I hope this helps,
Elaine
