Autosol and sequence file
by Stefan Knight 02 Jun '14

02 Jun '14

I don’t seem to have much luck with Phenix these days… Trying to run Autosol from the GUI but the process aborts immediately complaining that a sequence file is required to run Autosol. I have given it a sequence file in fasta format that is recognised as such when added. I’ve also tried instead pasting the sequence into the Crystal info window but that didn’t help. Grateful for any tip on how to convince Phenix it has all it needs to get going ;-). Thanks, Stefan ------------------------------------------------------------------------------------------------------- Stefan D.

How to add difference map peak value to B-factor column in Phenix-Coot after isomorphous difference map?
by Murpholino Peligro 01 Jun '14

01 Jun '14

Hi all. How to add a difference map peak value to B-factor column in Phenix-Coot after isomorphous difference map? Because what I get (after Phenix Isomorphous Difference Map) is a pdb with the peaks (chain A) and holes (chain B) with their positions given by UNKnown atoms, 1 for occupancy and in the B-column their peak-or-hole value. I would be happy if I could get the actual atoms with positions and the peak-or-hole value in the B-column. Thanks again and again.

molecular replacement keeping hetatms?
by Murpholino Peligro 27 May '14

27 May '14

Can I do molecular replacement with phenix/phaser, keeping all the waters from the first model from the first data set? >From here ( http://www.phaser.cimr.cam.ac.uk/index.php/Molecular_Replacement#WATER), I should change all the HOH labels to something like WWW. Then I guess that I should put HOH labels again in the solution model, for the following refinement in phenix.refine. Is that it?... Any suggestions? thanks again!

(no subject)
by Fulvio Saccoccia 27 May '14

27 May '14

Dear phenix users and developers, in the past I usually used the fix_rotamers=true options to fix some residue issues. Now, this option is lacking (I currently use the dev-1702 version of phenix) but I was wondering if some other option does replace it. In addition, I would like to know better how real_space_refinement works; is there any tutorial or presentation about it? Thanks in advance -- Fulvio Saccoccia, PhD Dept. of Biochemical Sciences Sapienza University of Rome 00185, Rome (Italy) Phone: +39 06 4991 0556 https://www.researchgate.net/profile/Fulvio_Saccoccia/?ev=hdr_xprf

Three positions open at the MAX IV Laboratory
by Marjolein Thunnissen 23 May '14

23 May '14

The MAX IV facility, the largest and most ambitious Swedish investment in research infrastructure, will be the brightest source of x-rays worldwide and will replace the existing laboratory, which today consists of the storage rings MAX I, II and III. The new MAX IV facility will become operational in June 2016. To extend the suite of already funded beamlines, MAX IV Laboratory is planning the next set of beam lines. Therefore The MAX IV laboratory in Lund has opened two positions within the life-science division. We are looking for two beamline scientists, one for the biomedical imaging beamline MEDMAX and one for the microfocus beamline MicroMAX. For both these positions the scientist will be overseeing the development, construction and commissioning of the MedMAX, respectively MicroMAX beamline from its conceptual stage to full operation. Both beam lines are planned to be cutting edge beam lines, fully exploiting the excellent properties of the MAX IV 3GeV storage ring. In addition we are also looking for a software engineer to be engaged in the design of the MX software infrastructure at the beamline for protein crystallography which is under construction, BioMAX. More information on these positions can be found at https://www.maxlab.lu.se/positions and the links within this page, or from our Life-Sciences director Tomas Lundqvist . best regards Marjolein Thunnissen [cid:3A2194AC-734C-45EB-B5A7-CE7FC0F0F1BC] Marjolein Thunnissen Science Coordinator MX MAX IV Laboratory Lund University P.O.

any idea what is this? (unidentifiable blob in electron density map)

1) 2FOFCWT PH2FOFCWT bue map (front1.png) (process: XDS->Aimless within CCP4i->MR with Phaser->Phenix.refine/coot->Phenix-refine-withwaters/coot) 2) FWT PHWT purple map (front2.png) (Output from Aimless and calculate Fs with refmac within coot with last pdb from 1st line) What do I have in the crystal? NaCl, Sodium acetate, water, lysozyme and some complexes (~ 400 daltons) that chelate Cu2+ Is there like a gallery of crazy-looking blobs that are explained with something ....real and possible? (that would be great help for the newb) Thanks in advance. links to screenshots right here: https://www.dropbox.com/s/rzjepvr8genolxi/front1.png https://www.dropbox.com/s/0iycf4lh5y726x4/front2.png https://www.dropbox.com/s/xx5kvgn91p763ei/faraway.png (1.0 rmsd for both maps above and 3.5 for the "red and green maps")
