Detailed Description

This class implements different scores for peaks found in SRM/MRM.

It uses scores based on different parameters of the peaks from the individual transitions and stores them individually. The idea and the scores are based on the following paper: Reiter L, Rinner O, Picotti P, Huettenhain R, Beck M, Brusniak MY, Hengartner MO, Aebersold R. mProphet: automated data processing and statistical validation for large-scale SRM experiments. Nat Methods. 2011 May;8(5):430-5. Epub 2011 Mar 20.

The currently implemented scores include:

xcorr_coelution: Cross-correlation of the different transitions
xcorr_shape: Cross-correlation shape score (whether the maximal Cross-correlation coincides with the maximal intensity)
library_rmsd: normalized RMSD of the measured intensities to the expected intensities
library_correlation: correlation of the measured intensities to the expected intensities
rt_score: deviation from the expected retention time
elution_fit_score: how well the elution profile fits a theoretical elution profile
