Hi there, My Phenix.Refine run crashes because of non-availability of dictionary file for "ACP", a non-hydrolyzable ATP. Could this ligand be added to the next nightly build? Phenix.Refine suggested using "ReadySet", but that also failed. I sent the error reports to [email protected], all emails bounced back. Refmac runs fine. Thanks! -Gyan -- Gyanendra Kumar, PhD Associate Scientist, St. Jude Children's Research Hospital, Department of Structural Biology, 262, Danny Thomas Place, MS-311 Memphis, TN 38105 Cell: 631-875-9189 https://www.linkedin.com/in/gyanendrakumar https://scholar.google.com/gyanendrakumar https://scholar.google.com/citations?user=lnil0IQAAAAJ&hl=en https://www.researchgate.net/profile/Gyanendra_Kumar3 http://stjude.academia.edu/GyanendraKumar -------------------------------------------------------
