Re: [ccp4bb] Free Reflections as Percent and not a Number

2015-01-04 Thread Pavel Afonine
Hi Ed, I didn't see any way to refine with no free set in phenix, even with > least-squares target function, xray_data.r_free_flags.ignore_r_free_flags=true will make phenix.refine use all reflections. Obviously, reported Rwork=Rfree in this case. This works for any available refinement target.

Also it may have worked more as expected if I let it get a little farther away from the starting point before trying to return. If there is a circle of confusions of points in parameter space that give the same target function value (due to nearly perfect compensation of parameters in a small r

I didn't think about that. Yes, weights were being re-optimized each time. On 01/04/2015 04:39 PM, Ian Tickle wrote: Hi Ed The R, Rfree and RMSDs will all depend to some extent on the Wa factor and this may depend on the starting point, assuming of course that the program is automatically adj

Hi Ed The R, Rfree and RMSDs will all depend to some extent on the Wa factor and this may depend on the starting point, assuming of course that the program is automatically adjusting the Wa factor according to some criterion (you didn't say). The obvious way to check this would be to keep the Wa
