Correlation Calculator for Metabolomics Data
The Correlation Calculator is a standalone Java application providing various methods of calculating pairwise correlations among repeatedly measured entities. It is designed for use with quantitative metabolite measurements such as MS data on a set of samples. The workflow allows inspection and/or saving of results at various stages, and the final correlation results can be dynamically imported into MetScape (version 3.1 or higher) as a correlation network.

Input File Format
For this release, input files are required to be in CSV format. Input files should be tables of measurements of metabolites across multiple samples. Metabolites must be labeled, but sample labels are optional. Samples may be in either rows or columns. The example input file does not have labeled samples, and its samples are in rows.
