Re: [ccp4bb] number of frames to get a full dataset?

2020-06-22 Thread David Schuller
The old saying was degrees, not frames. If your frame width is not 1 degree, the result will differ accordingly. One factor is whether the detector is centered or offset, and whether it is large enough to get the entire pattern. If the detector is offset, you are not getting the full

There are lots of places where you could find this information (many textbooks, articles, etc.) but one that I use for classes is quite good due to ease of understanding. It’s part of the Proceedings of the CCP4 Study Weekend on Data Collection and Processing. There are other quite excellent

[ccp4bb] number of frames to get a full dataset?

2020-06-22 Thread Murpholino Peligro
Hi. Quick question... I have seen *somewhere* that to get a 'full dataset we need to collect n frames': at least 180 frames if symmetry is X at least 90 frames if symmetry is Y at least 45 frames if symmetry is Z Can somebody point where is *somewhere*? ...also... what other factors can change

A further note on assembly search: since April the RCSB PDB offers structure search for assemblies. See the "Structure Similarity" section in https://www.rcsb.org/search/advanced. This works only for PDB-deposited structures but we are working on making it available for 3D coordinates submitted by

Thanks everyone for recommendations. The AKTA currently lives in a cold room hence all of our purifications have been optimised at 4C, and i'm reluctant to transition them to RT. Also, most of our columns are not jacketed. On Sun, 21 Jun 2020 at 18:19, Boniecki, Michal wrote: > Hi Alan,

Dear Matthew, at your resolution, 1.7A, you are seeing a large difference in resolution limits. I'd be curious to know how much "anisotropy" you have in the single number anisoB. Could you share it? As to building felxible loops or peptide, I suspect you anisoB to be mild (<40A2 for your
