**Input(s)**

*One sample* : lumpy search structural variations inside a single sequencing dataset

*Two samples*: lumpy search structural variations inside and across two sequencing datasets from two samples

Analysis of sample replicates is not implemented yet in this wrapper

*BAM files*: Only BAM alignments produced by BWA-mem have been tested with this tool

**Sequencing method**

*Paired-end sequencing*: Both ends of library fragments have been sequenced, resulting in two paired sequencing datasets

*Single-read sequencing*: Only one end of library fragment has been sequenced, resulting in a single sequencing dataset. Under these conditions, evidences of structural variation are obtained only from splited read alignments

*Read length*: The length of the sequencing reads in the library. This information is required only for paired-end sequencing data

*Additional options*: refer to lumpy-sv_ documentation and the publication (doi 10.1186/gb-2014-15-6-r84)

**lumpy-sv manual**

Read the lumpy-sv_ documentation for details on using lumpy.
