Method Summary

static Spectrum.Peak[]	analyze(float[][] spectra, float startMz, double interval, Smooth2D smooth2d, float minPeak) scans.length should be 2^n for efficiency NOTE: will not return maxima in first or last scan, or bottom/top mz value NOTE: returns array index, not scan numbers
static Spectrum.Peak[]	analyze(org.fhcrc.cpl.toolbox.proteomics.Scan[] scans, org.fhcrc.cpl.toolbox.FloatRange rangePeaks)
static Spectrum.Peak[]	analyze(org.fhcrc.cpl.toolbox.proteomics.Scan[] scans, org.fhcrc.cpl.toolbox.FloatRange rangePeaks, Smooth2D smooth2d, float minPeak) find local maxima after smoothing using smooth2d, peaks returned with scan numbers
