Verticall repair - rrwick/Verticall GitHub Wiki

The verticall repair command is a simple tool to repair an assembly, making it suitable for use in verticall pairwise. Specifically, it removes any ambiguous bases, splitting contigs wherever they occur. The result is an assembly containing only A, C, G and T. You should only need to use this command if verticall pairwise refuses to accept an assembly as input.

Example usage

Repairing one assembly, saving to a new file:

verticall repair -i assembly.fasta -o assembly_fixed.fasta

Repairing one assembly, overwriting the original:

verticall repair -i assembly.fasta -o assembly.fasta

Repairing all assemblies in a directory, overwriting the original files:

for f in *.fasta; do
    verticall repair -i "$f" -o "$f"
done

If you have a lot of assemblies, you can run that loop in parallel:

N=16
(
for f in *.fasta; do
   ((i=i%N)); ((i++==0)) && wait
   verticall repair -i "$f" -o "$f" &
done
)
