Hi, not directly related but I wanted to know how to extract from the PDB all the PHENIX/CCP4 refined structures currently deposited. Do I use the "text" search in quarry to get the result or do I use the software? I tried it for both but seems to give different results (no's). I tried for another refinement package (shelx) and same, different no's Using software, and looking for contains 320 using text search 130 Is there another way to get structure of a certain resolution ?
