FlexPred takes a protein structure in PDB format as input, and predict the fluctuation of each residue (Cα atom) by considering Cα atoms contact number with set of cutoffs (16, 15, 18, 12, 8, 6, 20, 22 [Å]) of the protein with the Support Vector Regression. As an output program create CSV file with data and fluctuation plot.
For details, please read our paper M Jamroz, A Kolinski & D Kihara "Structural features of proteins that predict real-value fluctuation of globular proteins"
