MatrixRider-package: Calculate total affinity and occupancies for binding site...

Description Author(s) Examples

Description

Calculates a single number for a whole sequence that reflects the propensity of a DNA binding protein to interact with it. The DNA binding protein has to be described with a PFM matrix, for example gotten from Jaspar.
