Hello all, The omit_map in the new gui (version 1.5) is great, but I can not include a twin law when calculating the omit map, thus the result is very messy unclear maps. I do not know if 1.6 has the solution or not, I am still lobbying our computer guy to upgrade to it... Is there a way from the command line i can include the twin law in autobuild so I can calculate the omit map, or can I just add it into the eff file? My other solution has been to use the create maps function with my data and pdb with ligand removed. This works, giving me a nice Fo-DFc map, but it would be nice to be able to show a true omit map for the ligand, as is customary in most structure papers I have run across. Thanks in advance for any help you can provide!
