==========
Xcms.Group
==========

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

After peak identification with xcmsSet, this tool groups the peaks which represent the same analyte across samples using overlapping m/z bins and calculation of smoothed peak distributions in chromatographic time. Allows rejection of features, which are only partially detected within the replicates of a sample class.

|xcms.fillPeaks             | xset.RData      | rdata.xcms.group   |
+---------------------------+--------------------------------------+

The output file is an xcmsSet.RData file. You can continue your analysis using it in **xcms.retcor** tool as an next step and then **xcms.fillPeaks**.

----------
Parameters
----------

Method to use for grouping
--------------------------

**mzClust**

    | Runs high resolution alignment on single spectra samples stored in the RData file generated by the **xcmsSet tool**.

**density**

    | Groups peaks together across samples using overlapping m/z bins and calculation of smoothed peak distributions in chromatographic time.

**nearest**

    | Groups peaks together across samples by creating a master peak list and assigning corresponding peaks from all samples. It is inspired by the alignment algorithm of mzMine.


------------
Output files
------------

xset.group.Rplots.pdf

xset.group.RData: rdata.xcms.group format

    | Rdata file that will be necessary in the third and fourth step of the workflow (xcms.retcor and xcms.fillpeaks).
    

------

.. class:: infomark 

The output file is an xset.group.RData file. You can continue your analysis using it in **xcms.retcor** tool.

Changelog/News
--------------

**Version 2.0.5 - 04/04/2016**

- TEST: refactoring to pass planemo test using conda dependencies 


**Version 2.0.4 - 10/02/2016**

- BUGFIX: better management of errors. Datasets remained green although the process failed

- UPDATE: refactoring of internal management of inputs/outputs

- UPDATE: refactoring to feed the new report tool


**Version 2.0.2 - 02/06/2015**

- IMPROVEMENT: new datatype/dataset formats (rdata.xcms.raw, rdata.xcms.group, rdata.xcms.retcor ...) will facilitate the sequence of tools and so avoid incompatibility errors.

- IMPROVEMENT: parameter labels have changed to facilitate their reading.
