  1. Results show the total size of the compressed files when considering all mzXML files within each MassIVE experiment, as well as the compression ratio (denoted by C.R.). We also included the standard deviation, denoted by std. The compression ratio and the gain of MassComp with respect to gzip is computed as in Table 1. Results for experiment MSV000080905 are split into different Plates, as provided in the MassIVE repository, in addition to the overall performance. All sizes are expressed in MBs.
