Splits an mzML file into multiple parts.
This utility will split an input mzML file into N parts, with an approximately equal number of spectra and chromatograms in each part. N is set by the parameter parts
; optionally only spectra (parameter no_chrom
) or only chromatograms (parameter no_spec
) can be transferred to the output.
Alternatively to setting the number of parts directly, a target maximum file size for the parts can be specified (parameters size
and unit
). The number of parts is then calculated by dividing the original file size by the target and rounding up. Note that the resulting parts may actually be bigger than the target size (due to meta data that is included in every part) or that more parts than necessary may be produced (if spectra or chromatograms are removed via no_spec/
.no_chrom
)
This tool cannot be used as part of a TOPPAS workflow, because the number of output files is variable.
