calculateAverageMass: Function computing theoretical average masses.

In ditti2/BRAIN: Baffling Recursive Algorithm for Isotope distributioN calculations

Description

Function computing the theoretical average masses for chemical components composed of carbon, hydrogen, oxygen, nitrogen and sulfur (e.g. peptides).

Usage

calculateAverageMass(aC)

Arguments

aC	List with fields C, H, N, O, S of integer non-negative values (if any field is ommited, then its value is set to 0).

Details

Mass is calculated in Daltons.

Value

Average mass (numeric)
