Similarity matrix
	* File organisation : on line by similarity pairs with the first ion ID, the similarity value and the second ion ID, tabular separated ==> Fist_Ion_ID \\t Similarity_Value \\t Second_Ion_ID
	* Example:
	
.. image:: similarity_matrix.JPG
	:width: 800
	
Data matrix file
	* "variable x sample" **dataMatrix** : tabular separated file of the numeric data matrix, with . as decimal, and NA for missing values; the table must not contain metadata apart from row and column names; the row and column names must be identical to the rownames of the variable metadata (see below)

Variable metadata file
	* "variable x metadata" **variableMetadata** tabular separated file of the numeric and/or character variable metadata, with . as decimal and NA for missing values

.. class:: warningmark

For more information about input files, refer to the corresponding "W4M HowTo" page:
http://workflow4metabolomics.org/sites/workflow4metabolomics.org/files/files/w4m_TableFormatForGalaxy_150908.pdf


Mass differences list
	* A file containing list of known adducts, fragments or isotopes with the mass differences linked to them
	* Example:

.. image:: Adduct_fragment_list.JPG
	:width: 350

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

Take into account mass diffrences between 2 ions :
	* You can enter a list of mass differences that are known. The file must be organized with a first column for the mass difference type (isotope, fragment, etc...), a second column with the mass difference chemical formula (H+, -2H+K, etc...) and a third column for the mass difference value
	* If you are choosing to use a mass differences table, you have to choose a mass difference range that will be a threshold to accept or not a difference value as true (recognize a mass difference value in the file +/- this threshold).

Take into acount retention time :
	* You can use retention time as a criteria to group ions. You have to choose a value that will be use as intervalle : 2 ions are group when their retention time is equal +/- the threshold.

Choose the representative ion for each group, there are 3 possibilities to determine the representative ion :
	* The ion with the highest intensity (recommandated for LC/MS)
	* The ion with the highest mass
	* The ion with the highest "mass2 * intensity" value 
	* The ion with the highest mass between the 3 highest intensity of the group, except if the highest mass ion have an intensity < determined percentage of the highest intensity ion one (for exemple 50%) (recommandated for GC/MS)
	

---------------------------------------------------
	
--------------
Example of use
--------------

For UPLC/HRMS data, default parameters can be the following:
	* If a Pearson correlation is used, the default threshold can be set at 0.90
	* A delta RT of 0.1 min or adjusted depending on chromatographic systems
	* The use of the list of known adduct/isotope mass differences with a mass delta of 0.005 Da or adjusted depending on MS resolution
	* The choice of the ion with the highest intensity as the representative ion.
For GC/HRMS dataset, we recommend to use the same parameters but ignoring the list of mass difference and to choose the ion with the highest mass among the top highest intensity as representative.
