Hi Jamie, That sounds to me like your job has hung for some reason. It should say that it is running simulated annealing, and should have lines in the log such as "...trying gamma 0.500000, weight 30.000000" to indicate that gamma/weight pair has been started. The coordinate minimization step is usually quite fast, even for large structures. What version of Phenix are you using? It would be worth trying to run: libtbx.python /path_to_phenix/phenix_regression/den_restraints/tst.py to see if DEN works correctly on your system. That should complete in under a minute.

Hello All,

I am trying to use DEN refinement to refine a low resolution (5A) structure. I was able to succesfully start the run without crashes, and the run is currently going on 30 processors (I am trying to optimize the gamma and weight). My question is that the log file stopped not far in to the run and has not updated in 24 hours. The log file list every residue in my structure, and the last line simply says :

----------coordinate minimization before annealing----------

According to the computer cluster, the job is still running. I wanted to ask if this is OK or if it has stalled? Thanks.

Jamie
