RepeatExplorer2

RepeatExplorer2 includes utilities for Graph-based clustering and characterization of repetitive sequences in next-generation sequencing data and tools for the detection of transposable element protein coding domains.

How to user RepeatExplorer2:

  • RepeatExplorer2 can be used through Galaxy based web interface on our public server  at address https://galaxy-elixir.cerit-sc.cz. This server is provided as part of the Elixir CZ project and is maintained by CESNET and CERIT-SC that are participants of this project.
  • Source code for local installation of RepeatExplorer2 can be found here.  Basic documentation  can be found in wiki.

Source code for the old version of RepeatExplorer server can be downloaded from Bitbucket. Basic RepeatExplorer documentation and installation instruction can be found in user manual

Example of output from RepeatExplorer2:

Analysis of Pinus sylvestris genome can be found here

SeqGrapher

SeqGrapheR is a program for vizualization in exploration of sequence based graphs generated in RepeatExplorer output. SeqGrapheR program is now deposited in CRAN repository. See also our SeqGrapheR manual and input data examples.
