This pipeline can be used to assemble a viral genome.

Usage

In order to run the complete multisample pipeline, you can run pipeline.wdl using Cromwell:

java -jar cromwell-<version>.jar run -i inputs.json pipeline.wdl

The inputs JSON can be generated using WOMtools as described in the WOMtools documentation.

The primary inputs are described below, additional inputs (such as precommands and JAR paths) are available. Please use the above mentioned WOMtools command to see all available inputs.

field	type	default
outputDir	String		The output directory.
sampleConfigFiles	Array[File]		The sample configuration files.

All inputs have to be preceded by pipeline.. Type is indicated according to the WDL data types: File should be indicators of file location (a string in JSON). Types ending in ? indicate the input is optional, types ending in + indicate they require at least one element.

Sample configuration

The sample configuration should be a YML file which adheres to the following structure:

samples:
  <sample>:
    libraries:
      <library>:
        readgroups:
          <readgroup>:
              R1: <Path to first-end FastQ file.>
              R1_md5: <MD5 checksum of first-end FastQ file.>
              R2: <Path to second-end FastQ file.>
              R2_md5: <MD5 checksum of second-end FastQ file.>

Replace the text between < > with appropriate values. MD5 values may be omitted and R2 values may be omitted in the case of single-end data. Multiple readgroups can be added per library and multiple libraries may be given per sample.

Output

This pipeline will produce an assembled viral genome.
