IDDFinder

IDDfinder is a sequence-based approach to assess and visualize domain organisation in long intrinsically disordered proteins based on compositional biases. IDDfinder calculates the fractions of residue types in sliding windows of size 15. For each residue, k, the fraction of residues between k-7 to k+7 matching specific criteria is returned. All possible criteria and combinations can be applied, and the user can add as many features as desired. Each feature consists of a specific combination of amino acids yielding a positive contribution and a combination of amino acids yielding a negative contribution. For each feature any combination of proteinogenic amino acids (or X for unusual or unnatural amino acids) can be used, making the approach highly flexible and customizable depending on the protein examined and the properties of choice.
