  1. All sizes are expressed in MBs. Column mzXML denotes the size of the mzXML file, whereas Pairs contains the size of only the numerical data (including possible padding bits). Best results are highlighted in bold. C.R. denotes compression ratio, computed as 100−compressed size100/size of pairs. The gain of MassComp is computed as 1−MassComp size/other size.
