extractCTDT: CTD Descriptors - Transition

In road2stat/protr: Generating Various Numerical Representation Schemes for Protein Sequences

CTD Descriptors - Transition

Description

This function calculates the Transition descriptor of the CTD descriptors (dim: 21).

Usage

extractCTDT(x)

Arguments

x	A character vector, as the input protein sequence.

Value

A length 21 named vector

Note

For this descriptor type, users need to intelligently evaluate the underlying details of the descriptors provided, instead of using this function with their data blindly. It would be wise to use some negative and positive control comparisons where relevant to help guide interpretation of the results.
