Hi BB, I wanted to run phenix on a structure from the database with covalent serine-DNA links, 1zr4. The "ready-set" feature to prepare restraints from the pdb link records sounded lovely, but fails with the message "Error interpreting command line argument parament definition: "1ZR4.link.edits" RuntimeError: Unexpected end of input" This happens with either version 1.6.4-486 or a nightly build installed a few weeks ago (phenix 551; installed on 10/7/2010.) Am I asking to much to get nice Ser-DNA links without sweating blood to read the fine print? thanks, Phoebe ===================================== Phoebe A.
