Which file to download and install ?
Always install the current version. For each version the exe is provieded with or without database. The exe with database has preloaded databases of Gene ontology, protein-protein interaction from NCBI. These databases are useful to get the full functionality of the software. The ScreenSifter software will work without database as well. If you have downloaded ScreenSifter without database and later you want full features, you can update it directly from SCreenSifter. To do this in ScreenSifter, go to Connection -> Update ontology and Interaction database. Downloading and indexing the databse may take about 3 to 5 hours depending on the internet speed.
