The Osprey custom file format is a tab delimited text file that allows the user to load in a personal set of interactions data into the Osprey Network Visualization System. Osprey recognizes both a .txt and a .ocg extension for this file, but BioGRID will use the .txt extension for all downloads of this format. For more details on how to load an Osprey Custom Network, you can visit the Osprey documentation.
