Description Arguments Details Value Usage See Also Examples

Write the grouped xcmsSet to an mzTab file.

`object`	the `xcmsSet` object
`filename`	filename (may include full path) for the mzTab file. Pipes or URLs are not allowed.

The mzTab file format for MS-based metabolomics (and proteomics) is a lightweight supplement to the existing standard XML-based file formats (mzML, mzIdentML, mzQuantML), providing a comprehensive summary, similar in concept to the supplemental material of a scientific publication. mzTab files from xcms contain small molecule sections together with experimental metadata and basic quantitative information. The format is intended to store a simple summary of the final results.

None.
