set -o pipefail doesn't work in sh but works in bash

[conchoecia]

The first few lines of create_pseudohaploid.sh are:

#!/bin/sh

set -o pipefail

but running the script returned the error set: Illegal option -o pipefail.

I changed the first line to:

#!/bin/bash

and everything worked fine. Ubuntu 16.04.

Fixed. Good luck!
