QSOlevel: Quasi-Sequence-Order (QSO) Descriptor
In missuse/ragp: Mining for Hydroxyproline rich glycoprotein sequences

Description Usage Arguments Details Value Note Author(s) References See Also

This function calculates the Quasi-Sequence-Order (QSO) descriptor with lag 12

1	QSOlevel(m)

`m`	A vector of k-mers

QSO descriptor is calculated based on two physicochemical distance matrices: Schneider-Wrede (Schneider and Wrede, 1994) and Grantham physicochemical distance matrix (Grantham, 1974)

A matrix with the Quasi-Sequence-Order Descriptor (dim: 64)
