Re: [ccp4bb] Lower b-factors with increasing T

2022-09-07 Thread Tom Peat
I think the basic question being asked is why are the B-factors going the 'wrong' way? That is, as the temperature increases, one might expect higher B-factors (at least that is what we are taught) whereas what Matt is seeing is the opposite- decreasing B-factors as one goes up in temperature

2022-09-07 Thread Phoebe A. Rice
I guess the big question is what is the question that you’re trying to address from those numbers? I’d be nervous about making conclusions about trends in B factors from just 1 data set per temperature. As you probably know, the B factors will reflect static differences in atomic position

In addition, I computed the wilson B.s 253 - 41 273 - 35.4 293 - 36.5 313 - 0.19 Looks like there is definitely an issue with the data scaling. Still looking for suggestions as to what to tweak. Matt To unsubscribe

[ccp4bb] Installing previous Coot version in a Conda environment

Hi Everyone, I'm experiencing some issues with Coot 0.9 which I have running under Mac OS when I try to use some older CCP4 packages. It seems to work fine on other computers running Coot 0.89. I think a good way to handle this issue is to download an older version of Coot to run in a

Hi everyone, I have a series of datasets at 253K (~2.0A), 273K (2.0A), 293K (2.0A), 313K (2.2A) and I am curious as to the details in determining B-factors. I have treated these datasets more-or-less identically for comparison's sake. I used DIALS to index, integrate, and scale the data. I

[ccp4bb] Two postdoctoral positions are available in the laboratories of Drs. Juan Du and Wei Lü at Van Andel Institute

The Du Lab and the Lü Lab are interested in understanding the molecular mechanisms of how the body perceives sensory information (e.g. taste, smell, vision, and temperature), transmits signals to the brain, and generates responses. We focus on ion channels involved in the basic senses. We
