Supernova (v.2.1.1) was used to assemble the linked reads with the following script. We used 660 million reads as input and all other default parameters.
#!/bin/bash -e
#SBATCH --nodes 1
#SBATCH --cpus-per-task=12
#SBATCH --ntasks=1
#SBATCH --job-name Supernova_EW
#SBATCH --mem=400G
#SBATCH --time=168:00:00
#SBATCH --account=uoo02752
#SBATCH --output=%x_%j.out
#SBATCH --error=%x_%j.err
#SBATCH --mail-type=ALL
#SBATCH [email protected]
#SBATCH --hint=nomultithread
module load Supernova/2.1.1
supernova run --id=EW_10xSN \
--fastqs=/path/to/linked-read/fastq/files \
--maxreads=660000000
After the completion of the assembly we produced the assembly in fasta file with pseudohap
style with the following script
#!/bin/bash -e
#SBATCH --nodes 1
#SBATCH --cpus-per-task=2
#SBATCH --ntasks=1
#SBATCH --job-name Supernova_EW_fasta
#SBATCH --mem=1G
#SBATCH --time=00:10:00
#SBATCH --account=uoo02752
#SBATCH --output=%x_%j.out
#SBATCH --error=%x_%j.err
#SBATCH --mail-type=ALL
#SBATCH [email protected]
#SBATCH --hint=nomultithread
module load Supernova/2.1.1
supernova mkoutput \
--style=pseudohap \
--asmdir=path/to/working-directory-of-supernova/EW_10xSN/outs/assembly \ # this is a path to the output directory `assembly` created by supernova
--outprefix=./EW_10xSN
After running this script we will get the assembly called EW_10xSN.fasta.gz
We checked the assembly statistics with the Quast. Script here
