The dataset was retrieved from MetaboLights with the identifier number MTBLS79 Two groups from the entire study was downloaded: control and S. typhi carriage. The name files of control group are: 08GB, 09GB, and 14GB, which has the following native name 08_GB.cdf, 14_GB.cdf, and 09_GB.cdf in the MetaboLights database. For the S. typhi group the names are: 34GB, 24GB, 29GB, which has the native name of 34_GB.cdf, 24_GB.cdf and 29_GB.cdf in MetaboLights database.

Due to the large size of chromatograms, these data is a subset of the whole chromatograms from 7 min to 18 min of chromatografic run. If you would like to acces the whole formated chromatograms, please go to

The original study was developed by Näsström et al. (2018) .




A joined_chrom object containing four slots:


A named list with the two-dimensional chromatograms


The metadata containing two varaibles and six observations


The retantion time range of the chromatographic run


The modulation time
