SIR with sites from SAD?
by Francis E Reyes 17 Jul '08

17 Jul '08

I have a SAD dataset where autosol was able to find sites, but the resulting density modified map was uninterpretable. The unit cell for this SAD set was Unit cell: (53.2373, 53.2373, 186.446, 90, 90, 90) . I now have a heavy atom derivative. What's the format of autosol.inp (to be passed to phenix.runWizard AutoSol) that allows me to use the heavy atom sites from the SAD set as a basis for helping find heavy atom sites in the heavy atom derivative? Is it the same as SIR, except use ha_sites_file for the SAD solution? Native unit cell: [53.155600000000007, 53.1556000 00000007, 187.37970000000001, 90.0, 90.0, 90.0 Derivative unit cell: [53.1 82299999999998, 53.182299999999998, 187.59569999999999, 90.0, 90.0, 90.0].

Anomalous difference map calcluation
by Jendrek 16 Jul '08

16 Jul '08

Dear All, I'm looking at my anomalous difference map from phenix.refine and it seems more or less random distributions of electron density peaks. I know that the signal is there since I solved it with SAD. I'm using I(+/-) for refinement and everything seems to work fine except the map generation. The only thing that worries me is that during the creation of _data file for refinement DANO column was not preserved. Is it necessary for phenix.refine in order to generate the anomalous difference map? How can I make sure that the DANO column is preserved (if necessary)? And by the way why is anomalous map file not generated just coefficients in the mtz?

broken bonds in the substrate
by houjin zhang 11 Jul '08

11 Jul '08

Hi: I am trying to use phenix.elbow to generate restrains for a substrate. I notice that the PDB file produced by elbow contains some broken bonds. So I ran the elbow with the internal strings ATP. The output PDB file also harbors broken bonds. The --opt did help a little. But some bonds still look weird. I am wondering if this a bug or I just didn't install phenix right. I use the latest version of phenix and default setting. Thank you very much!! Houjin

Reminder: Crystallographic Computing School registration deadline approaching
by Ralf W. Grosse-Kunstleve 11 Jul '08

11 Jul '08

The registration deadline for the 2008 Crystallographic Computing School is in two weeks: *** July 25 *** The schedule of the program including abstracts from all speakers is available here: http://www.iucr.org/iucr-top/comm/ccom/kyoto2008/program.html This program puts a strong weight on fostering one-on-one interactions. There will be only 16 lectures of 45 minutes each (12 hours total) but more than 20 hours of tutorials and demonstrations. Don't miss this unique opportunity for close interaction with the developer community! On behalf of the organizing committee: A. L. Spek (Utrecht University , Netherlands) R.

PHENIX on OS X Intel 10.5 "need access to screen" error
by Ben Eisenbraun 10 Jul '08

10 Jul '08

Howdy, I have PHENIX 1.3-rc2 built on an OS X Intel 10.4 machine. It runs fine there, but using the same installation mounted via NFS, I get this error: This program needs access to the screen. Please run with 'pythonw', not 'python', and only when you are logged in on the main display of your Mac. I dug around in the program a bit to see if there was a script testing for the DISPLAY setting, but this seems to be generated in the wx-python bits: build/mac-intel-osx/base/Python.framework/Versions/2.5/lib/python2.5/site-packages/wx-2.8-mac-ansi/wx/_core.py contains the error message, as do a couple of other files in the /wx/ hierarchy. The PHENIX 1.3-rc2 I built on OS X 10.4 PPC works fine on the 10.5 PPC machines, so I'm a bit surprised it's failing on the Intel side. Does anyone know if a PHENIX built on 10.5 will work on a 10.4 machine? If it was really necessary, I could install versions built on both 10.4 and 10.5, but I'd prefer to avoid it if possible. Any insight on fixing this would be much appreciated. Thanks. -ben -- Ben Eisenbraun Structural Biology Grid Harvard Medical School http://sbgrid.org http://hms.harvard.edu

sugar chain cif file
by Daniele de Sanctis 08 Jul '08

08 Jul '08

Dear all, I have a trisaccharide in my structure, and I generate the cif file with elbow (see below). Unfortunately phenix.refine seems not recognizing the bonds C5-O1 between different units and is not keeping the chain together. As far as I could understand I should also use the keyword "apply_cif_link", but I couldn't find which syntax i should use.
