.cif file has 'UNK' auth_asym_id
by Kevin M Jude 14 Mar '25

14 Mar '25

I’ve finished refining a structure with three protein chains A, B, C. The pdb file looks ‘normal’ to me, but when I inspect the .cif file written by phenix, the auth_asym_id for chains B and C is ‘UNK’. label_asym_id is correct for all chains. I’m not really sure what the difference is between the auth_ and label_ fields. When I try to perform actions on the .cif file, I get duplicate atom label errors. Here’s a few example lines from the .pdb and .cif files, where auth_asym_id is field 6 and label_asym_id is field 16 ATOM 460 OXT PRO A 59 5.272 55.689 31.481 1.00 52.63 O ANISOU 460 OXT PRO A 59 6541 6212 7244 1448 1260 96 O TER ATOM 461 N ALA B 2 39.292 61.974 39.403 1.00 67.81 N ANISOU 461 N ALA B 2 7118 8729 9916 -1711 -388 2066 N ATOM 460 OXT .

AKM in Phenix
by lucas.santosouza＠outlook.com 07 Mar '25

07 Mar '25

Hi everyone, Is there still support for the generation of Average Kick Maps in Phenix? I am using both versions 1.21.2-5419 and the nightly build 2.0rc1-5555. I added kicked=True to the maps.params, but phenix.maps gives me "Unused parameter definitions: maps.map_coefficients.kicked (file "maps.params", line 53)". I also cannot see the "Kicked map" check box in the Create Maps GUI. Cheers, Lucas

Cryo_fit installation
by omar.debei＠unipr.it 28 Feb '25

28 Feb '25

Hi everyone, I was wondering if you could help me with installing cryo_fit on an Ubuntu machine. I followed the instructions here for the cryo_fit installation. Then, I tried to follow this guide to install gromacs_cryo_fit. However, I got stuck at the "Install using a provided script" step. Do I need to install GROMACS separately before proceeding? Any tips would be greatly appreciated! Many thanks, Omar
