Alternative conformation on special position occupancy wrong
by Kaiser, Jens T. 21 May '20

21 May '20

Hi, We have a case of a cofactor with 222 symmetry in two states on a special position ( 2-fold). When modelling one state, Phenix correctly restrains the occupancy to 0.5. When putting state 2 in alternative conformation group B, the occupancy of altconf A and B is restrained to 1.0, instead of 0.5; it seems like it does not recognize that the alternative conformations are on a special position.

Generating a polder map using coordinates
by Petr Kolenko 20 May '20

Dear colleagues, Is there a way to calculate the polder map in a selected box using coordinates instead of atom selection as shown in the "Generating a polder map with the compute_box option" website? Best regards, Petr

Solving a protein - ligand structure
by Tom Vanmarcke 20 May '20

20 May '20

Dear, We are trying to solve a protein structure that contains a ligand (polyoxometalate). We found the ligand in the electron density but through the middle of the ligand goes a 2 fold axis. For this reason, we placed the occupendency of the ligand on 0.50. When we try to refine the structure using phenix.refine, the ligand breaks down even when adding a cif restrain file. The cif restrain file contains information about atoms, angles and bond lengths. Is there a way to fix this problem?

Is there a way to evaluate batch pdb models with Malprobity in phenix?
by Jing Liu 19 May '20

19 May '20

Hi, I had generate a batch of pdb models (40-100) in rosetta and am wondering whether there is a way to evaluate these models in batch with Molprobity. For example, can I use phenix command line to do it and how? Or should I download the Molprobity and do it on my local computer? Really appreciate if anyone can share their experience.

Phenix 1.18 and rotamer outliers
by Xavier Brazzolotto 18 May '20

18 May '20

I’ve installed the latest stable Phenix version (1.18). I’ve noticed a clear difference in the final statistics (MOLprobity) compared to the previous version (1.17). A bit more of Rama outliers and the most noticeable in the Rotamer outlier score. Is there any reason that could explain such behaviour ? I am using Phenix under MacOS.

unit cell dimesions
by Thomas, Leonard M. 13 May '20

13 May '20

Hello All, I have run into something that has me a bit puzzled. When finishing up a structure we ended reprocessing the data to get nice statistics for deposition, I don’t want to get into that discussion. Upon reprocessing the unit cell dimensions shifted slightly, 0.05 A or so. The PDB file used had the unit cell from the original solution/refinement while the data set cell dimensions were different. I ran the newly processed reflection data set through the reflection editor in order to transfer the Rfree set. Now the really odd thing is that I ended up reprocessing a couple times and transferring over the Rfree set once more. The cell dimensions on the final reflection file is from not the original reflection file/PDB but one that was used with an intermediate cutoff between the two, it is not the cell dimensions in the input reflection either. Just for completeness the data were processed using XDS at SSRL. My question is where does phenix.refine pick up the unit cell dimensions and were does the reflection file editor pick them up?

How to compare between electron density maps?
by Murpholino Peligro 12 May '20

12 May '20

I want to compare electron density features of map A from protein A and map B from protein B... Because each map has a different rmsd level... ...what is the best way to compare electron density between maps? Is there a way to normalize maps or something like that? Thanks

With the ccp4bb at https://www.jiscmail.ac.uk/cgi-bin/webadmin I can search for a term in the archive. Is there something similar in the phenixbb? Thanks Or... is there a way to wget all the gz files?
