[Open Babel] Open Babel 2.3 unable to filter batch SDF files on basis of logP and ROTATABLE_BOND

I am using batch files from ZINC and trying to apply Lipinksi filter on it with openbabel. I am using the official documentation. Although obabel is able to filter on the basis of MW, HBD and HBA, it seems to failing with logP and Rotatable bonds. If I include logP and Rotatable bond, it converts "

The descriptor "ROTATABLE_BONDS" is used as an example in the online documentation but not actually implemented in the code. The easiest solution would be this: https://sourceforge.net/p/openbabel/mailman/message/30659149/ Add the following item to /"OBABEL_INSTALLATION_DIRECTORY"/data/plugindef

Dear Pascal, Thanks you for your help. Steps 1 and 2 work fine (i.e. conversion of smiles to 3D-sdf, then removal of hydrogens), but step 3 still does not work. The smiles of the small molecule I am using is ‘CC1=C(SC2=C1C(=N[C@H](C3=NN=C(N32)C)CC(=O)OC(C)(C)C)C4=CC=C(C=C4)Cl)C’ Can you or any

Dear Miro, Thanks for your help and suggestion. However, removing the space between –p and 7.4 (i.e. –p7.4) changes the syntax such that –p is no longer recognized as a real option parameter, and the command does not run. The small molecule smiles I am using is ’CC1=C(SC2=C1C(=N[C@H](C3=NN=C(N

Thank you so much. Silicos-it solved it for me. But I think it is really odd that they would include a function in the example of official documentation that doesn't actually exist. On Fri, Aug 5, 2016 at 5:42 PM, mirix [via Open Babel] < ml-node+s957263n4659421...@n4.nabble.com> wrote: > The des
