Hello, Could someone please advice me: 1) on the format (SDF) of the molecules database from the Asinex website http://www.asinex.com/download.htm; 2) on an internet site which specializes or has a lot of info on chemical databases; 3) on an internet site which specializes or has a lot of info on formats for chemical drawings (CT, mol, mol2, etc. ) Thank you very much in advance. Michael p.s. Has someone had already a look into these sdf files ? Do they only contain CT files ? I opened one 10MB zipped file which translated into a 137MB sdf file. chemweb: A list for Chemical Applications of the Internet.
