Updates for DDDT phase 2

Dear All,

We were in the process of optimizing the code and also implementing ways to make the Free Energy of Binding calculations efficient as well as scientifically robust as we had some issues due to the instability in the Molecular Dynamics Simulation while running the dengue and west nile re-scoring calculations.

Now we are in the process of submitting alpha test calculations and once they are in place, then we are planning to run the following calculations -
1. Re-scoring Free energy of binding calculations for first 2000 ligands from the results of the virtual screen with Autodock Vina and Maybridge and Chembridge Libraries (different than the phase 1 calculation because they used Autodock 4 and different library)
2. We also have put together another 600,000 compound library (with important libraries and drug like properties as criteria) that we are currently screening for dengue and westnile and we are planning to do 2000 re-scoring calculations from those results too.

Scientifically this is a very challenging and satisfying project and I appreciate all your contributions and I sincerely will try to do my best to make this project a huge success. Will keep updating my progress.

Thank you all,

Re: Updates for DDDT phase 2

Is it still difficult to make such workunits run correctly under Windows?

Re: Updates for DDDT phase 2

Thanks for the update, research updates on the crunching we do is the second best motivator for me after a cure for the disease of course!

Re: Updates for DDDT phase 2

@Usha,

What I'd like to understand is the repeated use of the dg05 prefix of these A-Type computations. Is this indicative of what you describe in the opening post as, to sum up, a continuation of the benchmarking and re-validation cycle against a well typed reference [mentioned in past]? We all are eager to know when the real crunch commences of the 18 or so targets that were identified some 2 years ago, at start of the DDDT2 phase. See https://secure.worldcommunitygrid.org/forums/wcg/viewthread_thread,28528, where there were proximately 1000 A-Type tasks in quorum 2 were indicated per target [we just had 921 passing through], where we done 300,000+ C-type of dg05 back in January. Just so we understand and not anyone launching into [recurrent] funny notions.

thanks
