Description

ABySS is a de novo, parallel, paired-end sequence assembler that is designed for short reads. The single-processor version is useful for assembling genomes up to 100 Mbases in size. The parallel version is implemented using MPI and is capable of assembling larger genomes.

Environment Modules

Run module spider abyss to find out what environment modules are available for this application.

System Variables

HPC_ABYSS_DIR - installation directory

How To Run

The abyss-pe is hardcoded to use mpiexec, so you need to set the following variable in your abyss job script before calling abyss-pe to explicitly allow mpiexec usage, which is disabled by default:

export HPC_USE_MPIEXEC=1

 <!--Modules-->
-==Execution Environment and Modules==
+==Environment Modules==
-To use abyss with the environment modules system at HPC the following commands are available:
+Run <code>module spider {{#var:app}}</code> to find out what environment modules are available for this application.
-===Single threaded version===
+==System Variables==
-Get module information for abyss:
+* HPC_{{uc:{{#var:app}}}}_DIR - installation directory
- $module spider abyss
+{{#if: {{#var: exe}}|==How To Run==
-Load the application module:
+The abyss-pe is hardcoded to use mpiexec, so you need to set the following variable in your abyss job script before calling abyss-pe to explicitly allow mpiexec usage, which is disabled by default:
- $module load abyss
-===MPI version===
-Load Intel compiler:
- $module load intel/11.1
-Load MPI implementation:
- $module load openmpi/1.4.3
-Load the application module:
- $module load abyss
-'''Note:' since version 1.3.4 the MPI version can be loaded simply as
- $module load abyss/1.3.4-mpi
-To load the single-threaded version of abyss after the MPI version was loaded purge the modules and load abyss module or simply unload the openmpi module and the abyss module will be reloaded to a single-threaded version automatically.
- module purge
- module load abyss
-or
- module unload openmpi
-The modulefile for this software adds the directory with executable files to the shell execution PATH and sets the following environment variables:
-* HPC_ABYSS_DIR - directory where abyss is located.
+ export HPC_USE_MPIEXEC=1
-* HPC_ABYSS_BIN - executable directory
