[ccp4bb] reminder Postdoc CryoEM postion -deadline August 31

2022-08-26 Thread Panne, Daniel (Prof.)
Dear all,

A reminder that we currently have an open postdoc position in our Institute! 
Closing date is August 31st 2022.
 
The Panne group focuses on signal processing on enhancers and how 3D genome 
organisation contributes to various aspects of genome function. For examples of 
recent work see Nature 578, 472–476 (2020); NSMB 27, 233–239 (2020); Nature 
562, 538–544 (2018).

We are located at the the Leicester Institute of Structural and Chemical 
Biology (LISCB) is a cross-disciplinary entity that brings together 
internationally renowned research in structural biology, single molecule 
approaches and chemical biology at the University of Leicester. The Institute 
provides access to world-class research facilities, including X-ray 
crystallography, biological NMR spectroscopy, single molecule microscopy and 
the state-of-the-art Midlands Regional Cryo-EM facility.

About you
Successful candidate should have a background in structural studies by single 
particle cryoEM. They must have a track record in conducting internationally 
competitive research. We are looking for a creative and ambitious person with 
good communication skills and keen to work on challenging projects.

LISCB is one of five flagship research institutes recently established by the 
University of Leicester, UK. We have excellent access to state-of-the-art 
structural biology technologies including a Krios cryo-EM microscope equipped 
with K3/BioQuantum and in house GPU cluster for data processing.

Re: [ccp4bb] Quantifying electron density inside of a given volume

2022-08-26 Thread Tim Gruene
Dear Neno,

when I asked the same question a few months ago, I ended up writing my
own program. We used it for our study of coking in the zeolite ZSM5
(https://doi.org/10.1002/anie.202205413). It is not at all user
friendly, and it reads in FCF files, rather than MTZ files. I can
send you the source code nevertheless in case you are interested, or a
linux binary. It is easy to create an FCF file from your MTZ file with
e.g. pdb2ins and a quick run of SHELXL with 'CGLS 0'.

Best,
Tim
