Compute the Average Standard Deviation for a Set of Spectra and a Given Cutoff Point
avesd(Ma, cutoff)
Ma |
A matrix with rows the m/z values and columns samples/spectra |
cutoff |
A number of m/z |
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.
A real number.
