Re: [phenixbb] DEN refinement is crashing

I've been having the same problem. No matter what settings I use my final R factors are a lot higher than the starting ones. Using default settings they blow up from 31/32 to 50/60 :/ I've gotten them back down to 35 with cartesian annealing but they are still higher than the starting ones and the maps are not any better. With the torsion annealing I can lower them by lowering the starting temperature but even if I go down to 1000K they are still higher than what I start with. I usually optimize both gamma and weight automatically too... I tried running it with individual sites/individual adp with/and without NCS (trying both cartesian and torsion). I also tried using homologous reference models solved at higher resolution... If you come up with suggestions for what else to try I would love to hear them :) cheers, Melania On Apr 2, 2012, at 8:45 AM, Mario Sanches wrote:

Hi Jeff,

I ran it with XYZ and Individual B-factors refinement. I am sending you the inputs right now so you can do a test.

Thanks again,

Did you run your DEN refinement with optimization? If not, that could explain the behavior. It could also be the default refinement settings.

I would be interested in your input files to see why your R values are going up so much, but hopefully with better defaults this won't happen.

It went to completion. However, the Rwork/Rfree where higher than what I had before (original R + 20%). Since it is stil under development I will not read to much into it and wait for a newer version :-)

I will be happy to provide the inputs if the developers want to use it on a test.

Thank you again for your help,

I was using the latest stable PHENIX version but now downloaded the latest nightly build. It seems to be running fine now, even thought he job is still running. I will let you know of the output once it is finished.

Thank you again,

I've not encountered that bug before, but as Nat said I would suggest trying a more recent installer if you have not.

If you still encounter crashes, could you send me your input files off-list so I could try to replicate the problem here? Everything will be kept confidential.

As an aside, DEN refinement will soon be separated out as its own program, with GUI, to allow for more sensible default parameters and directed control.

Thanks, Jeff

The problem is that Python crashes all the time, always at the same point (see portion of the log output below). Is it a known bug? Is DEN incompatible with some of the options in refinement? My resolution is 2.9A by the way.

Thank you for your inputs.
