MaSuRCA¶
MaSuRCA is an assembly algorithm for both PacBio and Illumina data that combines the benefits of De Bruijn graph and Overlap-Layout-Consensus assembly approaches.
MaSuRCA is available as a module on Apocrita.
Usage¶
To run the default installed version of MaSuRCA, simply load the masurca
module:
$ module load masurca
$ masurca
USAGE: masurca <config_file>
For usage documentation, run masurca --help.
Example job¶
Selecting the number of threads
To prevent overloading a compute node, you should include the
NUM_THREADS=X parameter in your configuration file, where X is equal
to the number of cores requested.
Serial job¶
Here is an example job running on 2 cores and 4GB of memory:
#!/bin/bash
#$ -cwd
#$ -j y
#$ -pe smp 2
#$ -l h_rt=1:0:0
#$ -l h_vmem=2G
module load masurca
