lcms

time

The data set consists of a 100 x 2000 x 3 array <code>lcms</code>, a vector <code>time</code> of length 2000 and a vector <code>mz</code> of length 100. The LC-MS data in the array are a subset of a larger set measured on a tryptic digest of E. coli proteins.

Parametric Time Warping aligns patterns, i.e. it aims to
        put corresponding features at the same locations. The algorithm
        searches for an optimal polynomial describing the warping. It
        is possible to align one sample to a reference, several samples
        to the same reference, or several samples to several
        references. One can choose between calculating individual
        warpings, or one global warping for a set of samples and one
        reference. Two optimization criteria are implemented: RMS (Root
        Mean Square error) and WCC (Weighted Cross Correlation).
