Description
Computes error of the parent ion mass to charge measurement from
experimentalMassToCharge and calculatedMassToCharge.
The returned value is in points per million (ppm).
Usage
1
mass_measurement_error(object)
Arguments
object
An instance of class "MSnID".
Details
It may be more common to compute "mass measurement error".
However, the practical difference in "mass measurement error" and
"mass to charge measurement error" is negligible. Moreover, the
instruments measure mass/charge ratio, not mass per se.
Value
Returns mass to charge measurement error in "ppm" units.
