[ccp4bb] Reading LCF files.

For those who suffer from 80's nostalgia, I have worked-out a simple-man's way of recovering the reflection data from this, now obsolete, format. Its here: https://readingccp4lcffiles.blogspot.com and it works for most of my VAX lcf files. Just thought this might be of interest as the question h

You should not adjust the error model manually, instead please select the button "use auto corrections" and rely on the automatically adjusted error model. This way you do not have to analyze the changes in the resolution shells. D. On 2019-07-01 01:44 PM, Weston Lane wrote: When you fix th

When you fix the error model in HKL2000 you only have a set of numbered boxes (1-20) and knowing which box corresponds to which resolution bin and corresponding chi^2 value isn't apparent without looking at the log file. Besides using a script the easiest method IMO is graphically: hover your mo

But then you would loose the info on the solvent mask parameters. These are only implicitly stored in FC_ALL. These values too are things to get from data.json. Cheers, Robbie On 1 Jul 2019 15:31, Eleanor Dodson wrote: Old program RSTATS would give r factor.. But easist to run 0 cycles of REF

If you are using SFTOOLS you might as well use the CORREL function to calculate things. Datamining is easier though. Every PDB-REDO entry has a data.json file that has all the numbers you need. Cheers, Robbie > -Original Message- > From: CCP4 bulletin board [mailto:CCP4BB@JISCMAIL.AC.
