Dear Sir/Madam:

I have the following script for spades, quast, and prokka. It is working perfect. However, there are several contigs with less than 200 in length. I need the minimum contig length 200. Spades manual does not say how to do it. Can you please help me with this?

module load spades quast prokka python/2.7

combined_data=combined.quast.results.txt


while read r1 r2 output; do

spades.py -1 $r1 -2 $r2 -o $output
spades.py -1 $r1 -2 $r2 -o $output -t 4 --only-assembler

cd $output
quast.py contigs.fasta
prokka --genus Escherichia -usegenus contigs.fasta

cd ..
echo -e "$output\t$(tail -n 1 $output/quast_results/latest/transposed_report.tsv)" >> $combined_data

done < group15.txt

Thanks a lot. Baha
