In pkrog/biodb: biodb, a library and a development framework for connecting to chemical and biological databases

Close match PPM

Description

Matches peaks between two spectra.

Usage

closeMatchPpm(x, y, xidx, yidx, xolength, dppm, dmz)

Arguments

x	sorted M/Z values (ascending order) of input spectrum (no NA).
y	sorted M/Z values (ascending order) of reference spectrum (no NA).
xidx	indices of the M/Z peaks of x, taken from the original spectrum ordered in decreasing intensity values.
yidx	indices of the M/Z peaks of y, taken from the original spectrum ordered in decreasing intensity values.
xolength	The length of the output.
dppm	The M/Z tolerance in PPM.
dmz	Minimum M/Z tolerance.

Value

A list of results.
