Dear Sorin,

I mean this ZINC15:
this one should be ready to dock. I just need the length file for todo.all.

Which program can make fourth hierarchical level input file?

Best regards.

is Enamine-REAL-2018q12_isomers.smi.splitted1000_ind_tgz_tar downloadable?

Dear w1234,

You can download the Enamine-REAL (or subsets of) via Log in | Virtual Flow via our Tranche Browser (you first have to register).

Also, if you haven’t already, please have a look at our tutorials page: Tutorials | Virtual Flow

Kind regards,


Have a look at VFTools:

VFTools is a a loose collection of additional tools and scripts which can be useful when using VirtualFlow, for example for preparing workflows or postprocessing completed workflows.
