WebThe first mpileup part generates genotype likelihoods at each genomic position with coverage. The second call part makes the actual calls. The -m switch tells the program to use the default calling method, the -v option asks to output only variant sites, finally the -O option selects the output format. In this example we chosen binary compressed BCF, … WebFor example an average depth of 50 would ideally result in a normal distribution centred on 50, but the presence of repeats or copy-number variation may reveal multiple peaks at approximate multiples of 50. The first column is an inclusive coverage range in the form of [ …
