Description of the bug

When attempting to download and install chipseq-2.0.0 with singularity containers, the 'bowtie2 align' image gives a container string parsing error. I noticed the container string in main.nf for this module has nested double quotes instead of internal single quotes - is it terminating early?

container "${ workflow.containerEngine == "singularity" && !task.ext.singularity_pull_docker_container ?
