For this exercise we will use the epi2me-labs/wf-human-variation pipeline. Find information on the pipeline at https://labs.epi2me.io/workflows/wf-human-variation/
...
Approximate run time: Variable depending on whether it is targeted sequencing or whole genome sequencing, as well as coverage and the individual analyses requested. For instance, a 90X human sample run (options: --snp --sv --mod --str --cnv --phased --sex male) takes less than 8h with recommended resources.
NOTE: in contrast to the nf-core/sarek pipeline that we used in session 2, the epi2me-labs/wf-human-variation pipeline runs in ‘local’ mode (needs large amount of CPUs and RAM memory), while the nf-core/sarek pipeline will use a ‘pbspro’ mode, where the pipeline will submit individual jobs to the HPC cluster and define the CPUs and memory for each task individually.

Let’s inspect the HTML reports for wf-human-alignment-report.html, wf-human-snp-report.htmland wf-human-sv-report.html.
NOTE: To proceed, you need to be on QUT’s WiFi network or signed via VPN.

ClinVar = The pipeline reports mutations overlapping known Clinical variants of interest (see:
wf-human-snp-report.html)Structural variants : The dataset used in this workshop does not contain real TVsSVs, rather it reports Insertions or Deletions in regions where there are “N” bases on chromosome 20.
