What it does
-------------

This tool performs cluster analysis of RNA-seq dataset(s) based of Graudenzi et al."`MaREA`_: Metabolic feature extraction, enrichment and visualization of RNAseq data" bioRxiv (2018): 248724.

Accepted files are:
    1) For "Recon 2.2 rules" or "HMRcore rules" options: RNA-seq dataset. The user can specify a label of output prefix (as e.g. "K=3 *dataset*" and "K=4 *MyDataset*");
    2) For "Custom rules" option: custom rules dataset, custom map (.svg) and RNA-seq dataset. The user can specify a label of output prefix (as e.g. "K=3 *dataset*" and "K=4 *MyDataset*").

Optional files:
    - custom GPR (Gene-Protein-Reaction) rules. Two accepted formats:

        * (Cobra Toolbox and CobraPy compliant) xml of metabolic model;
        * .csv file specifyig for each reaction ID (column 1) the corresponding GPR rule (column 2).
    - custom svg map. Graphical elements must have the same IDs of reactions. See HmrCore svg map for an example.

The tool generates:
    1) Clusters n1 - n2 (n1 and n2 refer to min and max number of clusters): class-files (as many files as the chosen different number of clusters k to be tested) specifying the class/condition each sample belongs to;
    2) Log: a log file (.txt);
    3) *dataset* elbow evaluation method: diagram (.pdf) of elbow evaluation method;
    4) *dataset* dendrogram (optional): dendrogram (.pdf) if the user chooses to produce a dendrogram (hierachical clustering).

RNA-seq datasets format: tab-separated text files, reporting the expression level (e.g., TPM, RPKM, ...) of each gene (row) for a given sample (column). Header: sample ID.


Example input
-------------

**RNA-seq dataset**:						

@DATASET_EXEMPLE@

**Custom Rules Dataset**:

@CUSTOM_RULES_EXEMPLE@

**Custom Map**:

*see the generated HMRcore .svg map for example*



.. class:: infomark

**TIP**: If your data is not TAB delimited, use `Convert delimiters to TAB`_.

.. class:: warningmark

If dendrogram it's too populated, each path and label can be not clear.
