======================
mixOmics blocks.splsda
======================

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

The blocks.splsda function is part of the mixOmics package for exploration and integration of Omics datasets.
Performs N-integration and feature selection with Projection to Latent Structures models (PLS) with sparse Discriminant Analysis.

-----------
Input files
-----------

For each block (min 2 blocks):
==============================

+------------------------------+------------+
| Parameter : num + label      |   Format   |
+==============================+============+
| 1 : Data matrix              |   tabular  |
+------------------------------+------------+
| 2 : [opt] Variables metadata |   tabular  |
+------------------------------+------------+

Variables metadata files are optional.
If a file is provided, output metadata will be appended to the input file, otherwise a new output file will be created.

1. Data matrix format
    * Rows = variables, Columns = samples
    * First row = samples name. MUST be the same and in the same order in every block as well as in the sample metadata file (transposed)
    * First column = variables name

2. Variables metadata format
    * Rows = variables, Columns = metadata
    * First row = metadata column names
    * First column = variables names. MUST be the same and in the same order than in the associated data matrix

Global input files:
===================

+-----------------------------+------------+
| Parameter : num + label     |   Format   |
+=============================+============+
| 1 : Samples metadata        |   tabular  |
+-----------------------------+------------+

By default, the last column of the samples metadata matrix will be used as samples description factors.
If it's not the case, the column number can be inputed in the `Sample description column number` parameter.

1. Samples metadata format
    * Rows = samples, Columns = metadata
    * First row = metadata column names
    * First column = sample names. These names must be identical (transposed) and in the same order than for the blocks data matrices

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

For each block (min 2 blocks):
==============================

Block name
    Name of the block. If not provided, this will default to the input filename

Number of variables to select for each component
    If set to 0 (default), all variables will be considered in the model

Global parameters:
==================

Sample description column number

Number of components to include in the model

Correlation between all blocks

Advanced options:
=================

Scheme

Mode

Maximum number of iterations

Scale

Init

Convergence stopping value (tol)

Near zero var

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

mixomics_blocksplsda_output.rdata
    | rData output
    | Contains the `mixomics_result` R object containing the result of the block.splsda function

mixomics_blocksplsda_{input_sample_metadata_name}
    | tabular output
    | Identical to the input Sample metadata file with appended columns from the result of block.splsda function

mixomics_blocksplsda_blocks_output
    A collection with the variable metadata output files (mixomics_blocksplsda_block_{block name}_variable_metadata) for each input block
