Chapter 6 Caveats

  • A good internet connection is required. Retrieving fastq can be really slow and is thus a bottleneck.
  • fasterq-dump will randomly segfault. At first we thought this was caused by connection problems, but running ping ruled this out. Apparently, the segfault is a known issue.
  • The workflow will inevitably fail if you try building the genome’s index on a machine with less than ~30 GB of RAM available.
    • As a general rule, tweak all parameters to reasonable values that fit your setup and needs. We don’t know your hardware, you do ;)
