By default it uses trimmomatic to trim the reads, BWA (or minimap2 for nanopore) to align to the reference genome and bcftools Here is an example schematic for illumina paried-end data Trimmomatic performs a variety of useful trimming tasks for illumina paired-end and single ended data. Select and set multiple options for command-line bioinformatic tools. log This will send part of the output of trimmomatic to a file in the same folder as the trimmed reads, which multiQC will Build virtual cohorts from 188K+ pediatric samples, including whole genome sequencing & RNA-Sequencing data: rebrand. Your line ends with ; done, done is the shell syntax to end a loop (for, while, until), but you never start any loop. Available operating systems: Linux 64, OS X INTEL; Primary The cls command will clear the command prompt console.
