file location changed
by Cygler, Miroslaw 14 Oct '19

Hi, In order to allow synchronization of files on my mac with the cloud server I had to move all files used by Phenix to a new directory, including the main Phenix folder. How do I change the paths to these files in phenix so that they are accessible to the software? Phenix would not start without the main Phenix folder returned back to the old location. How do I rectify this as well? Thanks for your help, Mirek

Masked FSC estimation failure
by ze li 12 Oct '19

12 Oct '19

Hello: I have three cryo-ET full maps, not in halves, to estimate their resolutions. I intended to estimate the resolution of the maps with the high-resolution models in the PDB databank. Is it the best to get a map to model FSC estimation at 0.5 cut-off? I calculated three maps with cryo-EM module in Phenix, but only one gives the masked and unmasked curves, the other two only have the unmasked results.I tried many times but failed to figure out the questions of these two maps. What is the possible reason for them? Or Is there any other ways to get the unmasked and masked FSC? Thank you for your help. Sincerely, Ze

Berkeley Server Outage (Starting October evening 8th)
by Paul Adams 12 Oct '19

12 Oct '19

Dear Colleagues, as a result of the increased frequency of wildfires in California the power company is taking steps to reduce risk under certain weather conditions. This entails shutting down electricity to regions that are experiencing dry windy conditions. We have been informed that the weather this week meets their criteria for a shutdown in our part of the Bay Area. Therefore several of the Berkeley servers will be shut down today and will return later in the week. This will affect: - The Phenix web site (http://phenix-online.org/) - The DIALS West web site (http://dials.lbl.gov/) - The CCI web site (http://cci.lbl.gov/) - The Structural Biology Technology Portal (http://technology.sbkb.org/) Bug reports and emails requesting help should be queued and we will receive them once the servers are back online. We apologize for any inconvenience.

positional restraints in real_space_refine?
by Daniel Larsson 08 Oct '19

08 Oct '19

Hi all, I'm working on a cryo-EM reconstruction where I have some flexible low-resolution elements (RNA double helices). They have different orientations relative to my reference model, but I would like to model them in the approximately correct position. I've tried real_space_refine with morphing and simulated annealing, but neither accomplish what I want. Now I'm thinking of cutting out these helices and manually position them approximately where I want them. But I fear that this will case headache at the "joint". Is it possible to use the manual positions as a reference for positional restraints, but use the original model as the reference for the torsion angles. Is this possible with real_space_refine? Or is there a better way of refining this structure? Regards, Daniel När du har kontakt med oss på Uppsala universitet med e-post så innebär det att vi behandlar dina personuppgifter.

reference torsion restraints for nucleic acids in real_space_refine
by Daniel Larsson 07 Oct '19

07 Oct '19

Hi all, In phenix.real_space_refine, I'm using a reference model for torsion restraints for a RNA/protein complex. I noticed in the log file under the section "Adding Reference Model Restraints (torsion)" that only the amino acid residues and some modified nucleotides are listed in the "Reference Model Matching Summary" but not the standard nucleotides. Does this mean that they are not restrained? I checked the _initial.geo file and there are no torsion restraints for the standard nucleotides in the "Reference torsion angle restraints" section. Are they not supported by default? My workflow was this: run ready_set on the initial model and then supply real_space_refine with a reference model and the ready_set cif file with the ligands.

Base-pair restraints and high resolution cryoEM maps
by Stephen Cusack 07 Oct '19

07 Oct '19

Dear All, (1) Is it possible to add RNA base-pair restraints into Phenix Real-space-refinement of a lowish resolution cryoEM structure? If so how? (2) We are also lucky enough to have some impressively high resolution cryoEM maps (2.4 A average) which show among other things hundreds of water molecules. I was wondering whether Phenix Real-space-refinement was really adapted to high resolution, e.g. it uses grouped B-factor refinement and has no water handling options (putting them in manually is a pain and you always miss some). How have other people dealt with these issues ? thanks for any help Stephen Cusack -- ********************************************************************** Dr. Stephen Cusack, FRS Head of EMBL Grenoble Group leader in the structural biology of protein-RNA complexes and viral proteins ********************************************************************** Email: cusack(a)embl.fr, stephen.cusack(a)embl.org Website: http://www.embl.fr Tel: (33) 4 76 20 7238 Secretary (33) 4 76 20 7123 Fax: (33) 4 76 20 7199 Postal address: EMBL Grenoble Outstation, 71 Avenue des Martyrs, CS 90181, 38042 Grenoble Cedex 9, France Delivery address: EMBL Grenoble Outstation, Polygone Scientifique, 71 Avenue des Martyrs, 38000 Grenoble, France **********************************************************************
