glfMultiples is a GLF-based variant caller for next-generation sequencing data. It takes a set of GLF format genotype likelihood files as input and generates a VCF-format set of variant calls as output.

Basic Usage Example

In a typical command line, a series of options controlling variant calling appear first and are followed by a trailing list of GLF-format likelihood files. Here is an example of how glfMultiples works:

  glfMultiples --minMapQuality 30 --minTotalDepth 60 --maxTotalDepth 240 -b YRI.SLX.vcf YRI/NA*.SLX.glf > YRI.SLX.log

Command Line Options

Basic Output Options

 -b baseCallFile                Specifies the name of the output VCF-format base call file
 -p threshold                   The threshold for base calling. Base calls will be made when their posterior likelihood exceeds threshold

Filtering According to Depth and Map Quality

 --minMapQuality threshold      Positions where the root-means squared mapping quality falls below this threshold will be excluded.
 --strict                       When the map quality is interpreted strictly, all three trio individuals must exceed minMapQuality 
                                before a call is made. Without the --strict option, reads for individuals below the threshold are ignored.
 --minDepth threshold                Positions where the read depth falls below this threshold will be excluded.
 --maxDepth threshold                Positions where the read depth exceeds this threshold will be excluded.

TODO

Support for X chromosome variant calling.

Support for two-pass depth filter that looks at the data to work out appropriate thresholds for shallow and deep coverage.
