Detailed Description
Linear Resampling of raw data with alignment.
This class can be used to generate uniform data from non-uniform raw data (e.g. ESI-TOF or MALDI-TOF experiments). Therefore the intensity at every position x in the input raw data is spread to the two adjacent resampling points. This method preserves the area of the input signal and also the centroid position of a peak. Therefore it is recommended for quantitation as well as for ProteinIdentification experiments.
In addition to the LinearResampler, this class also allows to fix the points at which resampling will occur. This is useful if the resampling points are known in advance, e.g. if one needs to resample a chromatogram at the positions of another chromatogram.
