The idea behind the OBITools project was to provide a set of UNIX command-line tools that mimic standard UNIX shell commands such as <code>grep</code>, <code>uniq</code> or <code>wc</code>, but which work on DNA sequence files. Unlike standard UNIX tools, where the processing unit is a line of text, with OBITools the processing unit is a sequence record. In addition, some commands implementing algorithms specific to the processing of DNA metabarcoding data have been added, making <abbr title="A set of unix command line tools for manipulating DNA metabarcoding data">OBITools</abbr> one of the sequence processing tools widely used on UNIX-like systems, suitable for the analysis of DNA metabarcoding data.</p>
