GuiltyTargets
=============
This is a tool for therapeutic target prioritization using network representation learning.

Installation
------------
Download this repository, go to the directory it resides and run:

.. code-block:: bash

    $ git clone https://github.com/phanein/deepwalk.git
    $ cd deepwalk
    $ pip install .
    $ cd ..
    $ # Install GAT2VEC, which depends on DeepWalk
    $ git clone https://github.com/ozlemmuslu/GAT2VEC.git gat2vec
    $ cd gat2vec
    $ pip install .
    $ cd ..
    $ # Actually install GuiltyTargets
    $ git clone https://github.com/guiltytargets/guiltytargets.git
    $ cd guiltytargets
    $ pip install -e .

Usage
-----
After that, you can use it as a library in Python

.. code-block:: python

   import guiltytargets

   guiltytargets.run(
       input_directory,
       targets_path,
       ppi_graph_path,
       dge_path,
       auc_output_path,
       probs_output_path,
       max_adj_p=max_padj,
       max_log2_fold_change=lfc_cutoff * -1,
       min_log2_fold_change=lfc_cutoff,
       entrez_id_header=entrez_id_name,
       log2_fold_change_header=log_fold_change_name,
       adj_p_header=adjusted_p_value_name,
       base_mean_header=base_mean_name,
       entrez_delimiter=split_char,
       ppi_edge_min_confidence=confidence_cutoff,
    )

This will create files in paths ``auc_output_path`` and ``probs_output_path``, where
the former shows the AUC values of cross validation and the latter shows the predicted
targets.

The parameters are explained below. A use case can be found under https://github.com/GuiltyTargets/reproduction

INPUT FILES
-----------
There are 3 files which are necessary to run this program. All input files should be found
under input_directory

1. ``ppi_graph_path``: A path to a file containing a protein-protein interaction network in the format of:

    +------------------+------------------+------------+
    | source_entrez_id | target_entrez_id | confidence |
    +==================+==================+============+
    | 216              | 216              | 0.76       |
    +------------------+------------------+------------+
    | 3679             | 1134             | 0.73       |
    +------------------+------------------+------------+
    | 55607            | 71               | 0.65       |
    +------------------+------------------+------------+
    | 5552             | 960              | 0.63       |
    +------------------+------------------+------------+
    | 2886             | 2064             | 0.90       |
    +------------------+------------------+------------+
    | 5058             | 2064             | 0.73       |
    +------------------+------------------+------------+
    | 1742             | 2064             | 0.87       |
    +------------------+------------------+------------+

    An example of such a network can be found [here](http://cbdm-01.zdv.uni-mainz.de/~mschaefer/hippie/download.php)


2. ``dge_path``: A path to a file containing an experiment, in tsv format. Rows show individual entries,
   columns are the values of the following properties:

   - **Base mean**
   - **Log fold change**
   - **Adjusted p value**
   - **Entrez id**

  The file may contain other columns too, but the indices and names of the above columns must be
  entered to the configuration file.

3. ``targets_path``: A path to a file containing a list of Entrez ids of known targets, in the format of

    ... code-block:: sh

        1742
        3996
        150
        152
        151

OPTIONS
-------
The options that should be set are:

- max_adj_p: Maximum value for adjusted p-value for a gene to be considered differentially expressed.
- max_log2_fold_change: Maximum value for log2 fold change for a gene to be considered differentially expressed
- min_log2_fold_change: Minimum value for log2 fold change for a gene to be considered differentially expressed
- ppi_edge_min_confidence: Minimum confidence score for the edges in PPI network.
- entrez_id_header: The column name for the Entrez id in the differential expression file.
- log2_fold_change_header: The column name for the log2 fold change in the differential expression file.
- adj_p_header: The column name for the adjusted p-value in the differential expression file.
- base_mean_header: The column name for the base mean in the differential expression file.
- entrez_delimiter: If there is more than one Entrez id per row in the diff. expr. file, the separator betweem them.
