The Flexibility-Rigidity Index (FRI) is a simple tool for quickly calculating atomic level flexibility from atomic coordinates.

Your result is a zip file including
  • Your original PDB file
  • Reduced PDB file corresponding to the choice of the structure
  • An extended PDB file with two additional columns for the atomic flexibility index and predicted b-factor, respectively
