MASSIF-1 10 year celebration symposium
by Matthew BOWLER 25 Oct '24

25 Oct '24

Dear CCP4 community, I would like to draw your attention to a one day symposium we are holding here in Grenoble to celebrate 10 years of fully automatic data collection at the ESRF/EMBL beamline MASSIF-1 - from starting with basic characterisation and data collection we now measure crystal volumes, dynamically adapt beam diameters, automatically collect and merge kappa sweeps, helical and multi-crystal data sets and even automatically mount crystals from trays using the EMBL CrystalDirect robot. With a great line-up of speakers we will highlight some of the research enabled by MASSIF-1, how it has inspired other beamlines around the world, as well as some history of the project. You can find more details in the attached flyer and register in the link below. We look forward to seeing you in Grenoble!

Bursaries available for CCP4 Study Weekend 2025 - Using software, AI and other methods to advance macromolecular models
by Karen McIntyre - STFC UKRI 25 Oct '24

25 Oct '24

Standard Student Bursaries As in year’s past, CCP4 has made funding available for students, to help with the costs of attending Study Weekend, in the form of a bursary. All students are eligible for a standard bursary which covers the registration fee plus one night’s accommodation in halls. Bursaries will be given out to all students registering during the early bird registration period – 26th September to 11th November 2024. Students obtaining a standard bursary will only need to pay for any additional night’s accommodation. Students wishing to stay in the hotel rather than Rutland halls, will have 1 nights accommodation subsidised at the halls rate and will therefore pay a reduced rate for this night. Additional nights accommodation will need to be paid at the standard cost. Please also note that should you obtain a bursary and cancel after the latest cancellation date of 6 December 2024 you WILL be liable to pay.  This is because we have had a number of students obtaining bursaries and then cancelling last minute.  Places can be transferred to other people at no charge.  Travel bursaries Limited funds will also be made available to help pay travel costs for students and young post-docs from non-UK laboratories. Please send a separate letter, signed by your supervisor and stating the expected cost of travel in pounds sterling, to justify applications for travel support. Supervisors are asked to nominate only one candidate from their Laboratory. Delegates are expected to travel by the most economic means possible. Candidates from less favoured regions will be given preference. Applications should be e-mailed to ccp4sw(a)stfc.ac.uk<mailto:[email protected]> : Lauren Giles CCP4 Study Weekend Travel Bursary Applications for travel bursaries need to be in by Thursday 31st October 2024.

working with composite models
by Dmitry Semchonok 24 Oct '24

24 Oct '24

Dear Colleagues, We're encountering an issue with composite model refinement and would appreciate your advice. Our scenario: 1. We built two separate models based on two subtracted maps of a single complex. 2. We have a lower-resolution map of the full complex. 3. We merged the two models into the full complex and refined it against the full map. The problem: When refining the merged model against the full map using real-space refinement in Phenix, the clashscore progressively worsens. Has anyone experienced similar issues, or can you offer suggestions on addressing this problem? Thank you for your insights. Best regards, Dmitry

About cryo-EM map sharpening in Phenix
by Shanti Pal Gangwar 16 Oct '24

16 Oct '24

Hello everyone, I'm working on anisotropic map sharpening in Phenix version 1.21-5207-00 with a cryo-EM map of a multiprotein complex. Should I provide the sequence files for each component individually, or would it be better to compile all the sequences into a single file? In addition, shall I provide the full sequence even if a segment of the protein is not resolved in the map? I would appreciate any advice! Shanti Pal

AQuaRef - issues with torch-cluster installation
by Martin Malý 16 Oct '24

16 Oct '24

Dear colleagues, I'm trying to install AQuaRef. However, I'm struggling with running `bash config/update_phenix.sh aimnet2` which is part of `bash build_into_phenix.sh aimnet2`. This script wants to install the python package torch-cluster. However, I'm getting the error: /opt/phenix/phenix-dev-5480/conda_base/lib/python3.9/site-packages/torch/include/torch/csrc/python_headers.h:12:10: fatal error: Python.h: No such file or directory 12 | #include <Python.h> | ^~~~~~~~~~ compilation terminated. error: command '/usr/bin/gcc' failed with exit code 1 [end of output] I'm getting the same error when I tried to install only this package using the command `qrefine.python -m pip install torch-cluster`. I have a laptop with Ubuntu 22.04. I have all the usual development packages installed (build-essential, linux-headers, gcc, g++, ...). According Python, I have libpython3-dev, libpython3.10-dev, python3-dev, python3.10-dev. I can see that qrefine.python has a version of 3.9, so I also installed libpython3.9-dev, python3.9-dev and python3.9-distutils from ppa:deadsnakes/ppa but it did not help. I am also attaching a full log from the torch-cluster installation. It seems that the package torch has been installed successfully in prior. Do you have please an idea what is wrong and how to fix it? Thank you. Martin

help for the 4.3 A dataset
by princeadam＠163.com 15 Oct '24

15 Oct '24

Dear colleagues, I am currently engaged in an endeavor to unravel the crystal structure through molecular replacement techniques. Regrettably, the resolution attained stands at a rather low mark, approximately 4.3 Angstroms, which poses significant challenges. Despite exhaustive efforts directed towards optimizing the crystal conditions, there has been no discernible improvement in the resolution. The structure in question is confined to a specific domain, and we have at our disposal two distinct conformational models sourced from the PDB database: one derived from X-ray data and the other from Cryo-EM. Our prime objective is to meticulously discern which of these two conformations aligns most accurately with our experimental context. To this end, we have employed both structures (X-ray and Cryo-EM) as templates for molecular replacement, yet the refinement process has hit a roadblock, hindering our progress. We are seeking a collaborator with experience in dealing with low-resolution data to assist in solving the structure. We are open to sharing first or corresponding authorships in the near future for this paper. Warm regards Hui

Building Rosetta for Phenix
by Martin Malý 14 Oct '24

14 Oct '24

Dear colleagues, I am dealing with a low resolution data set (~4 A, protein crystal structure) so I would like to explore phenix.rosetta_refine. I followed the instructions at https://phenix-online.org/documentation/reference/rosetta_install.html . I applied the patch in ${PHENIX_ROSETTA_PATH}/main/source/tools/build/site.settings . After several minutes of compilation (command rosetta.build_phenix_interface), I got an error. I re-run the command to get a log file which I'm attaching. Please don't you have any idea what's wrong? I use Ubuntu 22.04. Thank you. Best regards, Martin
