Detailed Description

SpectrumCheapDPCorr calculates an optimal alignment on stick spectra.

to save computing time only Peak Pairs that could get a score > 0 are considered which Peak Pairs could get scores > 0 ?
Peaks get a score depending on the difference in position and the heights of the peaks
pairs with positions that differ more than some limit get score 0

Parameters of this class are:

Name	Type	Default	Description
variation	float	0.001	Maximum difference in position (in percent of the current m/z). Note that big values of variation ( 1 being the maximum ) result in consideration of all possible pairings which has a running time of O(n*n)
int_cnt	int	0	How the peak heights are used in the score. 0 = product 1 = sqrt(product) 2 = sum 3 = agreeing intensity
keeppeaks	int	0	Flag that states if peaks without alignment partner are kept in the consensus spectrum.

Note:

If a section name is documented, the documentation is displayed as tooltip.
Advanced parameter names are italic.
