ORE: Outlier-RV enrichment
--------------------------

Cursory use of ORE (outlier-RV enrichment) is provided here, visit the `latest ORE documentation`_ for more details. Confirm the following are installed:

    - `Python >=3.5.0`_
    - `bedtools >=2.27.0`_
    - `samtools >=1.3 and bcftools >=1.6`_

Then, on the command line, install with

.. code-block::

    pip install ore

Example run

.. code-block:: bash

  ore --vcf test.vcf.gz \
      --bed test.bed.gz \
      --output ore_results \
      --distribution normal \
      --threshold 2 3 4 \
      --max_outliers_per_id 500 \
      --af_rare 0.05 0.01 1e-3 \
      --tss_dist 5000


Variants and gene expression are specified with :code:`--vcf` (line 1) and :code:`--bed` (line 2), respectively. The output prefix is provided with :code:`--output` (line 3). In this example, the outlier specifications :code:`--distribution` (line 4), :code:`--threshold` (line 5), and :code:`--max_outliers_per_id` (line 6) indicate that outliers are defined using a normal distribution with a z-score more extreme than two, and samples with more than 500 outliers are excluded. Variant information is specified with :code:`--af_rare` (line 7) and :code:`--tss_dist` (line 8) to encode that variants are defined as rare with a intra-cohort allele frequency at varying thresholds (≤ 0.05, 0.01, and 0.001), and to only use variants within 5 kb of the TSS.


Usage, visit the `latest ORE documentation`_ for more
