Re: [ccp4bb] Careless and negative Wilson B-factor

Dear Gyuhyeok, I have no first-hand experience with CARELESS. But my understanding is that CARELESS gives you normalized structure factor amplitudes; this "normalization" roughly corresponds to a removal (subtraction) of the Wilson B-factor from conventionally processed structure factor

Dear Eleanor,I was wondering if the model and structure factors with the negative Wilson B-factor can be deposited in the PDB or made interpretable for biochemical experiments.The data were initially processed in XDS and the CORRECT output (XDS_ASCII.HKL) was provided to

Dear Jon and Gyuhyeok the real connaisseurs (e.g. Kay Diedrichs, et al) will certainly respond much better to this! Redundancy is really high here (which is good of course), likely explaining the high-ish Rmerge. Indeed, “redundancy-aware“ indices, like Rpim, are much better, and actually

Hello, are the data from serial crystallography? The redundancy and the CC's are very good but the R-merge (an unpopular metric these days) is quite high? Cheers, Jon Cooper2 Sent from ProtonMail mobile Original Message On 6 Jan 2023, 08:17, 조규혁 wrote: > Dear all, > > I

The tool must have sharpened your data - sometimes enhancing the outer data does improve the electron density.. So I wouldnt worry about that "negative" B factor - it is doubtless a result of the "careless" run, and not presumably the one you got at the data processing step.. Eleanor On Fri, 6

Dear all,I recently tested a novel merging tool for crystallography data called Careless (https://github.com/rs-station/careless).When I used it on our 2.6 A-resolution structure in the I23 space group with a lipid bound structure, I noticed that the electron density surrounding the acyl chain was
