Alternatively, you can do it like this: phenix.pdb_atom_selection model.pdb "chain A" --write-pdb-file=chain_A.pdb or phenix.pdbtools remove=" not chain A" model.pdb Pavel On 12/3/11 2:47 PM, Jeff Headd wrote:

Hi Bradley,

You can use phenix.pdbtools to select a specified chain. The syntax is like this:

phenix.pdbtools keep="chain A" model.pdb

This will write out a new PDB file which only contains chain A.

Hi again,

I am trying to take a pdb and write out a new pdb with just a specified chain. I am trying to do this with the hierarchy but am unfamiliar with its functions How do I do this?

Thanks, Bradley
