MizaR

A sorting method for encoding metagenomic data

Installation

If required, install art and cmake tools:

sudo apt-get install art-nextgen-simulation-tools # for RunAll.sh
sudo apt-get install cmake

Then, install MizaR:

git clone https://github.com/cobilab/mizar
cd mizar/
chmod +x *.sh
./MizaR.sh --install
lzma -d VDB_MT_ALL_REF.fa.lzma

Running

For compressing a metagenomic FASTQ file:

./Mizar --reads reads.fq --database VDB_MT_ALL_REF.fa \        
 --output compressed_reads.fq.mr --threads 8

Parameters

To see the possible options type

./MizaR.sh

or

./MizaR.sh --help

The info menu contains the following information

Experiments

To run the analysis of increasing the number of reference sequences and coverage:

./RunAll.sh 1> report-stdout.txt 2> report-stderr.txt &

To run the respective plots:

./Plot_sequences.sh
./Plot_channels.sh
./Plot_coverage.sh

Internal programs

MizaR uses the following programs:
