The REPET package is a package integrating bioinformatics programs in order to tackle biological issues at the genomic scale. REPET consists in two main pipelines, TEdenovo and TEannot, which are dedicated to the detection, annotation and analysis of repeats in genomic sequences. These pipelines are specifically designed for transposable elements (TEs) detection and annotation.

  • TEdenovo - this pipeline starts by comparing the genome with itself using BLASTER. Then it clusters matches with GROUPER, RECON and PILER, programs specific for interspersed repeats. For each cluster, it builds a multiple alignment from which a consensus sequence is derived. Finally these consensus are classified according to TE features and redundant consensus are removed. At the end we obtain a library of classified, non-redundant consensus sequences.
  • TEannot - this pipeline mines a genome with a library of TE sequences, for instance the one produced by the TEdenovo pipeline, using BLASTER, RepeatMasker and CENSOR. An empirical statistical filter is applied to discard false-positive matches. Short simple repeats (SSRs) are annotated along the way with TRF, RepeatMasker and MREPS. Then, MATCHER, via dynamic programming, chains TE fragments belonging to the same, disrupted copy. A "long join" procedure is subsequently applied to connect distant fragments. Finally, annotations are exported into GFF3 or gameXML files.

The information here is applicable to LSU HPC and LONI systems.


A user may choose between using /bin/bash and /bin/tcsh. Details about each shell follows.


System resource file: /etc/profile

When one access the shell, the following user files are read in if they exist (in order):

  1. ~/.bash_profile (anything sent to STDOUT or STDERR will cause things like rsync to break)
  2. ~/.bashrc (interactive login only)
  3. ~/.profile

When a user logs out of an interactive session, the file ~/.bash_logout is executed if it exists.

The default value of the environmental variable, PATH, is set automatically using SoftEnv. See below for more information.


The file ~/.cshrc is used to customize the user's environment if his login shell is /bin/tcsh.


Modules is a utility which helps users manage the complex business of setting up their shell environment in the face of potentially conflicting application versions and libraries.

Default Setup

When a user logs in, the system looks for a file named .modules in their home directory. This file contains module commands to set up the initial shell environment.

Viewing Available Modules

The command

$ module avail

displays a list of all the modules available. The list will look something like:

--- some stuff deleted ---

---------------- /usr/local/packages/Modules/modulefiles/admin -----------------
EasyBuild/1.11.1       GCC/4.9.0              INTEL-140-MPICH/3.1.1
EasyBuild/1.13.0       INTEL/14.0.2           INTEL-140-MVAPICH2/2.0
--- some stuff deleted ---

The module names take the form appname/version/compiler, providing the application name, the version, and information about how it was compiled (if needed).

Managing Modules

Besides avail, there are other basic module commands to use for manipulating the environment. These include:

add/load mod1 mod2 ... modn . . . Add modules
rm/unload mod1 mod2 ... modn  . . Remove modules
switch/swap mod . . . . . . . . . Switch or swap one module for another
display/show  . . . . . . . . . . List modules loaded in the environment
avail . . . . . . . . . . . . . . List available module names
whatis mod1 mod2 ... modn . . . . Describe listed modules

The -h option to module will list all available commands.

Module is currently available only on SuperMIC.
