Description

This provides retention time alignment of MS data (both metabolomics and proteomics). Dynamic time warping (DTW) is used for pairwise alignment. There are multiple local distance and similarity functions that can be used between mass spectral intensity vectors including: Euclidean distance, cosine similarity and linear correlation. There is the option to visualise the alignment. The website itself (http://bibiserv.techfak.uni-bielefeld.de/chroma/) is now out of date and instead ChromA is now part of Maltlcms.
