4 DeFuse is a software package for gene fusion discovery using RNA-Seq data. The software uses clusters of discordant paired end alignments to inform a split read alignment analysis for finding fusion boundaries. The software also employs a number of heuristic filters in an attempt to reduce the number of false positives and produces a fully annotated output for each predicted fusion. 4 DeFuse is a software package for gene fusion discovery using RNA-Seq data.

10 The included tool_dependencies.xml will download and install the defuse code.
11 It will set the environment variable: "DEFUSE_PATH" to the location of the defuse install.

11 The included defuse source code is from: http://sourceforge.net/projects/defuse/files/defuse/0.4/defuse-0.4.3.tar.gz/download 14 The defuse.pl command relies on a configuration file to specifiy options, the location of reference data, and other applications that it depends upon: bowtie, bowtie-build, samtools, blat, fatotwobit, R, and Rscript.
12 (to install uncompress the defuse source and navigate to the tools dir and type make) 15
13 tar zxf defuse-0.4.3.tar.gz 16 The DeFuse galaxy tool can either construct the config.txt file that is mentioned in the defuse manual, or select an existing config.txt file in the users history.
14 cd defuse-0.4.3/tool 17 When constructing the config.txt file, the DeFuse tool uses the values selected in: tool-data/defuse.loc
15 make 18 The dictionary field in the tool-data/defuse.loc can be used to set fields in the config.txt file, including the site specific location of reference data and the paths to the other application binaries.
16 cd ../.. 19 The "Defuse parameter settings" are used to alter options in the config.txt file.
20
21 The DeFuse galaxy tool also generates a bash script to run defuse.
22 That script will attempt to edit the config.txt file to specifiy any unset paths to applications that defuse relies upon:
23 bowtie, bowtie-build, samtools, blat, fatotwobit, R, and Rscript
24 The script uses the using the shell "which" command to discover the application path, so the required applications should in PATH environment variable.
