Detailed Description

Linear Resampling of raw data.

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.

Note:
Use this method only for high resoluted data (< 0.1 Th between two adjacent raw data points). The resampling rate should be >= the precision.
Parameters of this class are:
