Advanced Methods for Ambient Crystallography at ESRF-EBS Workshop - 21-23 November 2023
by Matthew BOWLER 05 May '23

05 May '23

Dear all The ESRF and EMBL Joint Structural Biology Group, with the support of EU project Streamline, is organizing a workshop on sample preparation, data collection and data processing for Ambient Temperature Crystallography. ESRF and EMBL have been laying the groundwork for the future development of this field with two main projects: the refurbishment of MASSIF1 (https://www.esrf.fr/MASSIF1), including a CrystalDirect Harvester, allowing full automation of single crystal RT data collection and the new ID29 (https://www.esrf.fr/id29) for Time Resolved Serial Crystallography experiments with microseconds X-ray pulses. This 2.5 days workshop will cover the different practical and theoretical aspects of room temperature data collection and structure determination on the first day, followed by practicals at the beamlines and data processing on the following days. A total number of 10 participants will be selected and we will accept a limited number of participants’ samples to be tested during the workshop. There is no registration fee and meals and accommodation during the workshop will be provided free of charge. Bursaries are available to cover travel expenses for the participants. Deadline for application for the workshop is on 15th August. Applications can be submitted at the following link https://survey.esrf.fr/index.php/212282?lang=en More information is available at the following link https://www.esrf.fr/home/events/conferences/2023/amax2023.html Confirmed speakers and tutors include: Robert Thorne (Cornell) Marcus Fischer (St Jude) Daniel Keedy (CUNY) Silvia Russi (SSRL) Chia-Ying Huang (PSI) Sasha Popov (ESRF) Clemens Vonhrein (GPhL) Nicolas Coquelle (IBS) -- Matthew Bowler Project Leader MASSIF1@ESRF European Molecular Biology Laboratory 71 avenue des Martyrs CS 90181 F-38042 Grenoble France =================================================== Tel: +33 (0) 4.76.20.76.37 Fax: +33 (0) 4.76.20.71.99 http://www.embl.fr/ http://www.esrf.eu/MASSIF1 https://twitter.com/id30_massif1 https://www.embl.org/people/person/71918b7a010f129de27b37236c7ca90085113d74… ===================================================

Cryo_fit execution data test GTPases fails
by CUNIASSE Philippe 04 May '23

04 May '23

Dear all, After installing cryo_fit in phenix and gromacs_cryofit on my Macbook Pro M1, I now try to test the code using the example data GTPase. The job encounters immediately a problem but the GUI suggests that the job is still running. The log suggest that the first step did not run successfully (below). I presume setting the topology of the protein but I don’t know. Another question is how is it possible to set other parameters for cryo_fit (like ff…) in the GUI or should I run it in command line ? Thank you for your help and suggestions. Philippe.

If a user sees a message like "Fatal error: Atom xx in residue xx xxx was not found in rtp entry xx with xx atoms while sorting atoms." or "Fatal error: Residue xxx not found in residue topology database" Solution if these residue/atoms are important: Fix wrong names of atoms/residues. Running real_space_refine via phenix GUI will show which atoms need to be fixed. If gromacs amber03 force field doesn't have parameters for these residue/atoms, you may need to add appropriate parameters. If you added parameters, please email me (doonam.kim(a)pnnl.gov), I want to recognize your contribution publicly. Most MD simulation force fields do not support all kinds of rare residue/atoms. cryo_fit2 is under development to address this issue using phenix.eLBOW Solution if these residue/atoms are not important: Remove these "wrong" atoms/residues from user's input pdb file. Run cryo_fit again. Solution if user's input pdb file is big: Probably cryo_fit will change conformation just minimally, I would extract out these "wrong" atoms/residues from user's input pdb file, then add these extracted lines to cryo_fitted file later. Email phenixbb(a)phenix-online.org or doonam.kim(a)pnnl.gov for any feature request/help.
