Description

Compute the Average Standard Deviation for a Set of Spectra and a Given Cutoff Point

Usage

avesd(Ma, cutoff)

Arguments

Ma A matrix with rows the m/z values and columns samples/spectra
cutoff A number of m/z

Details

For a given cutoff point, the standard deviation of all spectra will be calculated at each m/z above this cutoff point. The resulting sd's are then averaged and returned.

Value

A real number.
