Annotation of transposable element families from unassembled sequence reads

What is Transposome?
Transposome is a command line application to annotate transposable elements from paired-end whole genome shotgun data. There are many tools to estimate the mathematical nature of repeats from short sequence reads. There are also a number of tools for analyzing repeats directly from a genome assembly. This tool allows you to infer the abundance of repeat types in the genome without a reference genome sequence. The output files make it easy to quickly summarize genomic abundance by transposable element class, superfamily, family, or any other level of the repeat taxonomy.
There is also a Perl API which allows you to build custom analysis pipelines, repeat stages of the analysis, or test a range of parameter values for each phase of Transposome (see the API Tutorial page for more information and the transposome-scripts repository).
With Docker, you can create a container to run Transposome with the following command:
docker run -it --name transposome-con sestaton/transposome
If you cannot use Docker, please see the INSTALL file included with this distribution to install Transposome on various operating systems.
Following installation (or starting a Docker container), get the Transposome configuration file:
curl -sL https://git.io/bPVv > transposome_config.yml
Next, edit the configuration file by specifying the location of data files and parameters for analysis. Note that if you downloaded manually, a configuration file can be found in the 'config' directory, or the configuration file on the Quick Start page can be copied into a text editor and saved locally. It makes no difference which way you create the configuration file, though the
curl method is faster.
Then, simply run the
transposome program, specifying your configuration file:
transposome --config transposome_config.yml
The name of the configuration file does not matter, this is just an example. Though, the format is important. It is also possible to run individual steps of the analysis from the command line. See the Quick Start wiki page for more details.
It is possible to run only one part of the Transposome package, the clustering methods for example, or create your own analysis methods to plug into Transposome. In addition, you can extend existing methods.
For all available methods, simply type
perldoc followed by the name of the class you are interested in
using. For example,
Available classes are:
Transposome Transposome::Annotation Transposome::Cluster Transposome::PairFinder Transposome::SeqFactory Transposome::SeqUtil Transposome::Run::Blast
SUPPORT AND DOCUMENTATION
