OpenChrom is a tool for gas chromatography and mass spectrometry. The focus is to handle data files from different GC/MS and GC/FID systems and vendors. Its functionality and algorithms can be extended using a flexible plugin approach, based on Eclipse RCP.

It is often necessary to smooth high frequency fluctuations out of data streams sequenced by time, position, etc. The 'smooth' utility applies such smoothing using the wavelet algorithm. This implementation of wavelet smoothing was optimized for use in a data stream. It was adapted from HMMSeg Wavelet.Java by Thomas E. Wilson, University of Michigan. HMMSeg Wavelet.Java was written by Andrew Hemmaplardh, University of Washington.

...The program aims to allow the identification of regions where the values of either the CN state or the LOH scores are the same in all the affected individuals, but none of the unaffected individuals have the same value. As well as visualising the CN state and LOH data, the program will also display Log(2) ratio, smooth signal and allele difference values that may also be obtained from the Affymetrix SNP 6.0 array (details on how to export the data are here). CN state, Log(2) ratio and the smooth signal data may be derived from either the SNP or CNV probes on the SNP microarray chip, where as the LOH and allele difference values are derived solely from the SNP probes.

Ordered Bijective Interpolated Warping (OBI-Warp) aligns matrices using Dynamic Time Warping with a one-to-one (bijective) smooth warp-function. It is ideal for the chromatographic alignment of complex mass spectrometry proteomics data.
