Dear all,

I am looking for a free generator (for Web-based applications) of 2D chemical structures in gif/png/... format from a SMILES/MDL input.

By adjusting a simple parameter you can go from speeds of 15-20 seconds/ligand upto 20 minutes/ligand. More info on speed is posted here: http://www.simbiosys.ca/ehits/ehits_speed.html We find that running in a relatively quick mode (40 - 60 sec / ligand) gives very good screening result. Then, you can easily move to a more accurate setting for the "hits" from the first screen for binding pose analysis. If you want to try it out, just fill out a demo request: http://www.simbiosys.ca/products/demo_request.html Best regards, Aniko -- Aniko Simon, Ph.D. SimBioSys Inc. http://www.simbiosys.ca/ Tel: 1-416-741-4263 > Sent to CCL by: "Jerome Baudry" [jerome=scs.uiuc.edu] > Dear All > > I have been using commercial applications to perform virtual high > throughput screening of virtual databases of compounds (a la ZINC) in > protein models.

Thanks a lot, >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Some years ago I did a bunch of DFT calculations on the complexation between NH3 and a series of coinage metal clusters. I used mainly the SDD ECP but also experimented with all-electron basis sets. With ECP effects of BSSE was pretty much negligible. Although I can't remember the rationale of it but I do remember my understanding back then was that the small BSSE effect with ECP can be genealized to other systems. One possible source of error could be the absence of polarization functions on the O atoms. When using ECP like SDD and Lanl2dz Gaussian by default assigns the D95 basis sets to the non-metal atoms. > From my experience using D95** instead of D95, that is augmentation of SDD and Lanl2dz with appropriate polarization functions on the non-metal atoms, gives substantial improvement in the calculated energetics. I am not familiar with the Lanl2mb basis you used so I don't know if it is amenable to similar basis set augmentation. I presume the size of the surface you calculate could be too large for augmented lanl2dz. In your situation a trick I may try is to assign polarization functions just to the atoms of the binding site. Wai-To Chan
