[ccp4bb] IDS in PDB

2025-03-03 Thread Italo Carugo Oliviero
A brief reflection on IDPs Increasingly, people with a computer science background are analyzing the data deposited in the Protein Data Bank. In the case of conformation disorder analyses, they consider residues that are explicitly stated to be disordered (the old REMAR 465 records). This is not

Hi, 1) maybe work on refining the protein structure first, so that your residual maps improve in quality. 2) Maybe only part of the peptide is ordered? Can you assign part of the sequence? Starting a bulky aromatic (e.g. W/Trip)? 3) do you have a way to QC your peptide? Is it still 11 residues in

Hi, Sorry, I haven’t had time to read all the posts in this thread, but do people think that these fancy new lightfield displays will be the preferred route for 3D visualization in the future? For more information, see https://www.arch.tamu.edu/app/uploads/2021/10/FoVI3D_DeepDrive.pdf Has any

Hi Wulf, As some folks indicated already: Quad-buffered Stereo using Nvidia 3DVision shutter glasses still works under Windows 11 - no need to despair as long as you still have the proper monitor and shutter glasses... Just checked it using a new PC with a cheap professional graphics card (N

Hi Pavel, Interesting! I have always been told that one should include only what could be seen. In this scenario, I would model hydrogens only if I had a sub 1 A resolution or if I had Neutron diffraction data. Thanks for the documentation. All the best __

Hi Clemens, I have a workstation running under Rocky Linux 8 with a Nvidia RTX A4000 graphics card plus the bracket for the 3-pin mini-DIN connection. The last Nvidia driver that both recognizes and activates the Nvidia 3D Vision IR emitter is the 525 driver which can be installed from the N

Just to clarify: Gnome never worked with 3D stereo in the past (gnome-shell is incompatible with switching off compositing), which is why is used XFCE. 3D stereo with Gnome works to my knowledge only under Fedora and more recent Red Hat Enterprise Linux versions (or clones of it). Unfortunately

Hi It looks like the peptide is bound close to a 2_fold symmetry axis, which can result in mistakes, so try to anchor your peptide registry using regions that are away from this axis (turn symmetry on in COOT to make sure you dont build it inside itself). Other than, that its just a case of t

Hi Wim, we had the problem with smeared/unreadable scroll-able menus in Coot with activated 3D stereo both under Debian 11 and Rocky Linux 8 using XFCE. This does not happen with Rocky Linux 8 using Gnome. I think, it has something to do with a different way of switching to 3D stereo under G

Greetings, It's hard to disagree with this! Resolution, occupancies, and B factors only indirectly suggest what's visible and what isn't — and they can be especially difficult to interpret correctly for non-specialists. Perhaps a local confidence measure — similar to pLDDT for predicted models — c

Hi Rafael, This is progressively getting further off-topic, so we may consider continuing this conversation off-list or under a different subject line. You are correct that "one should include only what could be seen". However: a) "What could be seen" is not always necessarily a hefty green blob
