General help

For general queries we recommend posting to Biostars or Bioinformatics Stack Exchange as these will reach a much larger audience and generally receive a faster response time than GitHub. Note, if you do post to both GitHub and an external site, please do mention this so we can see if the problem has been resolved already.
