[ccp4bb] Multiple Postdoctoral Fellowships available at the “Multiscale Research Institute for Complex Systems” at Fudan University of Shanghai

The Multiscale Research Institute for Complex Systems (MRICS) at Fudan University is located at the Zhangjiang Campus of Fudan University and is supported by the Shanghai High-level Talents Program. MRICS is strongly committed to the development of novel and effective multi-scale imaging techn

Re: [ccp4bb] Strange Pseudosymmetry Effects

Yes - in P1 if you have two molecules approximately related by X y z. And x+ 1/2 y z say then the spots along the axis a* will have h=2n weak. And the sections with h even will have very weak spots. If you calculate a Patterson for the data there will be a strong peak st 1/2, 0,0. But you say yo

Re: [ccp4bb] Map grid passing from ccp4 refmac mask?

In cco4i you can select “run and view com file” then edit the appropriate command into the com file. Not sure if you can change the file name extension on the command line though - I seem to remember extensions were cast in stone to simplify. Cataloging outputs. But you can always rename any file i

Re: [ccp4bb] Strange Pseudosymmetry Effects

Hi Jessica, If you see spots and they fit a lattice, you should use them. Use the b=10 solution in P1 that you have with 3 models (or two if one is iffy) and use that as a start model for MR in b=20 and start searching for the rest. Alternatively, use the b=10 model with stuff that looks decent a

[ccp4bb] Strange Pseudosymmetry Effects

Hello, I am wondering if pseudosymmetry can cause weak reflections that mimic the doubling of one unit cell axis' length. Has anyone seen something like this before? I am processing data from a small molecule sample collected with electron diffraction from multiple crystals. For the b axis, it i

[ccp4bb] Map grid passing from ccp4 refmac mask?

Dear Developers, I am wondering if there is a way to entice the REFMAC ccp4i input mask to accept and hand-off grid parameters into the subsequently running FFTBIG if I select the 'Generate weighted difference maps' option? Just a convenience issue. I can script it. Also the map file

[ccp4bb] PhD studentship ILL (France) / Keele University (UK)

Hi, An exciting opportunity exists for a PhD student based in the Life Sciences Group (https://www.ill.eu/lsg) at the Institut Laue-Langevin (ILL) in France. The project will focus on structural characterisation of a DNA transfer machinery and is of particular relevance to antibiotic resistance. T
