xcms findChromPeaks Merger
==========================

-----------
Description
-----------

This tool allows you to run one xcms findChromPeaks process per sample in parallel and then to merge all RData images into one.
The result is then suitable for xcms groupChromPeaks.

You can provide a sampleMetadata table to attribute phenotypic values to your samples.

@HELP_XCMS_NEWVERSION_31200@

@HELP_XCMS_NEWVERSION_3610@

@HELP_XCMS_NEWVERSION_3440@

**Version 3.0.0.0 - 08/03/2018**

- UPGRADE: upgrade the xcms version from 1.46.0 to 3.0.0. So refactoring of a lot of underlining codes and methods

- IMPROVMENT: a new dedicated tool "xcms plot chromatogram" will allow you to get TIC and BPI of your raw data.

- IMPROVMENT: the tool will now generate a sampleMetadata file if any was provided. It will be useful to add some further information for the normalization and statistics steps.

**Version 1.0.1 - 13/02/2017**

- IMPROVMENT: the tool will now raise an error if a sample isn't describe in the sampleMetadata file

**Version 1.0.0 - 03/02/2017**

- NEW: a new tool to merge individual xcmsSet outputs to be used by xcms.group
