Hi PhenixBB, Thanks for sharing information about the AIMS Awards with your colleagues! Many have told us they really appreciated it. We’ve had requests for more time - so we extended the deadline to December 9th! For anyone with a protein target of interest, the AIMS Award program can help you discover new molecular tools, start new drug development efforts, and get published. The program is open to investigators, postdocs, and graduate students worldwide. We encourage you to check out our flyer for more information: Flyer <http://bit.ly/37oIrS3> You can apply directly on the website: atomwise.com/aims. Please don't hesitate to reach out with any questions!

cryo-EM density modification
by Tom Terwilliger 19 Nov '19

19 Nov '19

Hi Phenix cryo-EM users, For those of you trying out density modification for cryo-EM (phenix.resolve_cryo_em), the automatic estimation of resolution in the current version uses unmasked resolution instead of masked, in some cases resulting in running density modification at too low a resolution. Consequently it is best with this version if you specify your nominal resolution. To run it you can type: phenix.resolve_cryo_em half_map_1.ccp4 half_map_2.ccp4 \ seq_file=seq.dat resolution=3.5 or something like that. It requires the current nightly build to run. You might also want to wait just a short while and a version that has this and a few other bugs fixed, a GUI, full documentation, and an example dataset will be out (hopefully this week). The full description of the method is at https://www.biorxiv.org/content/10.1101/845032v1 Let me know of any problems or suggestions! All the best, Tom T -- Thomas C Terwilliger Laboratory Fellow, Los Alamos National Laboratory Senior Scientist, New Mexico Consortium 100 Entrada Dr, Los Alamos, NM 87544 Email: tterwilliger(a)newmexicoconsortium.org Tel: 505-431-0010

Differences in refinement statistics
by Chancievan Thangaratnarajah 19 Nov '19

19 Nov '19

Hello, I have noticed differences in the refinement statistics between two different Phenix versions (see attachments) even though I am using the same cryo-EM map and model as input. The most notable difference are rotamer outliers, which were 0 % in Phenix 1.16-3549 and now 6 % in Phenix 1.17-3660. I was wondering whether anyone has noticed a similar behaviour? Or is there something that I have missed? Best, Chancie.

Error in sequence assignment
by Tom Terwilliger 18 Nov '19

18 Nov '19

Hi Nicholas, I'm afraid there isn't a way to say which sequence goes with which chain. I would suggest using the tool phenix.replace_side_chains. Give it 1 chain and 1 sequence and if they have the same length it should just put it in. If it doesn't work, try phenix.sequence_from_map which can do the same thing. Let me know if that doesn't do it! All the best, Tom T Date: Sun, 17 Nov 2019 17:07:16 -0500 From: Nicholas Gao <dominion146(a)GMAIL.COM> Subject: Specify chain assignment in sequence file for rebuild-in-place of phenix.autobuild Dear CCP4, I currently have an MR solution that has the wrong sequence. The pdb file of the solution contains 3 chains, and I'd like to use the rebuild-in-place functionality within phenix.autobuild to correct the sequence of all 3 chains. Phenix allows me to supply a sequence file as input for this job, it's not clear to me how I tell the program which sequence should be assigned to which chain. Anyone know how to do this?
