Re: [ccp4bb] Automated refinement convergence

2024-01-23 Thread Robert Oeffner
Thank you all for the replies. My goal was to learn about practical ways to achieve convergence during refinement even if the supplied model for the density will never be able to model the density adequately. I may experiment with refmac's ability to terminate refinement when a criteria has been

[ccp4bb] Automated refinement convergence

2024-01-18 Thread Robert Oeffner
Hi, I am wondering if authors of refinement programs would like to consider putting on their users wish list the ability of refinement programs to automatically terminate once the refinement has reached convergence. Various refinement metrics such as R factors, CC or RMS values typically will r

[ccp4bb] skewness in a good EM map?

2023-11-07 Thread Robert Oeffner
Hi, In crystallography one of the features of a good map is that the histogram of map values has skewness. Does this also apply to EM maps? Whereas X-ray maps depicts the electron density EM maps depicts the electrostatic potential as I understand it. Any pointers about skewness or not in EM ma

We build Phenix on all three platforms, i.e. Windows, Linux and MacOSX. Microsoft provides great C/C++compilers for free on Windows. One minor issue though is that since our software uses Python 2.7 binary compatibility with the python2.7 installer requires that the rest of Phenix is built with
