HyDRA - HIV Drug Resistance Analyzer
====================================

The HyDRA pipeline provides a pipeline for identifying drug resistance within a Next Generation Sequencing dataset. The pipeline takes as input the raw reads produced by a Next Generation Sequencer and produces a report detailing found drug resistance per sample.

Authors
-------

The HyDRA pipeline was developed by Eric Enns and David Peddle.

Stages
------

The HyDRA pipleine proceeds through the following stages:

1. Quality Control/Filtering
2. Reference mapping using bowtie2.
3. Variant Calling and filtering using a Poisson distribution.
4. AA Mutation Calling and filtering.
5. Drug Resistance report generation.

Details
-------

The following is an example for running the pipeline, using our included test dataset:
    * Output directory name: "/tmp/hydra_out"
    * Forward reads: "reads_w_K103N.fastq"

### Output ###

The detailed output directory tree looks as follows:

    /tmp/hydra_out/
        * align.bam
        * coverage_file.csv
        * dr_report.csv
        * filtered.fastq
        * hydra.vcf
        * mutation_report.hmcf
        * stats.txt

The description of each of these directories/files are as follows:

* __run.conf__: The configuration used when this output was produced.
* __reads_w_K103N/__: The results directory for the input file reads_w_K103N.fastq
    * __align.bam__: The alignment file in bam format.
    * __coverage_file.csv__: A file with one entry per line with the AA position and the coverage at the position.
    * __dr_report.csv__: A report detailing the drug resistant mutations found, above the reporting threshold (default: 1%).
    * __filtered.fastq__: The reads remaining after the filtering stage.
    * __hydra.vcf__: The variants found by the pipeline.
    * __mutation_report.hmcf__: The AA mutations found by the pipeline.
    * __stats.txt__: A log file detailing size after filtering and major stages.

The __dr_report.csv__ file lists all found drug resistant mutations (mutations included in the mutation database) which have frequency greater than the reporting threshold. An example of this file is given below.

Example: __dr_report.csv__

    Gene,Category,Surveillance,Wildtype,Position,Mutation,Mutation Frequency,Coverage
    RT,NNRTI,Yes,K,103,N,9.03,155

The __mutation_report.hmcf__ files is our custom VCF like file which details all of the AA mutations found by the pipeline. An example if this file is given below.

Example: __mutation_report.hmcf__
