Fetch Host

The fetch_host setting controls from which PDB server you download files when using the fetch command. You options are:
  • pdb
  • pdbe
  • pdbj
  • mirror URL with "divided" layout (new in PyMOL 1.6)

for the standard RCSB (pdb), pdb mirror in europe, and the pdb mirror in Japan.

New in PyMOL 1.3


The exact URL (or list of URLs to try) is stored in pymol.importing.hostPaths[type]. The fetch_host setting only applies to the incomplete (not starting with scheme://) URL entries there.


set fetch_host, pdb
set fetch_host, pdbe
set fetch_host, pdbj
set fetch_host,
set fetch_host, file:///local/mirror/pub/pdb
# Paths which are appended to fetch_host
import pymol
pymol.importing.hostPaths["cif"] = "/data/structures/divided/mmCIF/{mid}/{code}.cif.gz"
pymol.importing.hostPaths["pdb"] = "/data/structures/divided/pdb/{mid}/pdb{code}.ent.gz"
