Silent File

Silent file is a compact format file which stores multiple structures informations. Silent files can be generated by many Rosetta 3 simulations. Such as Abintio and Ligand Docking. You also can use silent file tools to combine regular pdb files to be binary format silent file to save computer storage spaces. We will briefly introduce silent file format here.

Protein Silent Struct is usually seen in the Abinitio outputs.

Binary Silent Struct File is very useful to compress multiple pdbs and save computer spaces.
