Generate reference SOM
-----

This tool generates a reference Self-Organizing Map using FlowSOM.

**Input files**

This tool require a valid FCS file or flowFrame as input.

.. class:: warningmark

Compensation and Transformation will NOT be applied with this tool.

**Parameters**

*Columns to use*

Please indicate the indices of the markers to use in the computation of the SOM in a comma-separated list.

.. class:: infomark

Tip: One of the tools in the FCS File Tools section can help check the markers and channels indices:

- Get list of markers and channels in FCS files.

*Number of meta-clusters*

Please indicate the exact number of meta-clusters expected.

*Grid dimension*

Please indicate the dimension of the grid for establishing the SOM. The dimension of the grid defines the number of clusters (height x width = cluster)

*Seed*

Please indicate a random number to use as seed. To make your analysis reproducible, use the same seed.

**Output files**

This tool produces a FlowSOM object and optionally two sets of plots, one representing the SOM Tree generated, and the other displaying each marker's contribution to the tree. A flat text file can also optionally be generated and used as input for vizualisation tools.

.. class:: warningmark

PDF are larger files that may take some time to load. It might be faster to download the PDF output once generated to open it locally.

-----

**Example**

*Output text file*::

   Marker1 Marker2 Marker3 ... Population
   34      45      12      ... 1
   33      65      10      ... 5
   19      62      98      ... 2
   12      36      58      ... 1
   ...     ...     ...     ... ...

*Node/Meta-cluster mapping file*::

   Node Meta-Cluster
   1    10
   2    9
   3    1
   4    9
   ...  ...

*FlowSOM tree*:
