Assembly-Free Detection and Quantification of Transposable Elements with dnaPipeTE.

Abstract

The detection and quantification of transposable elements (TE) are notoriously challenging despite their relevance in evolutionary genomics and molecular ecology. The main hurdle is caused by the dependence of numerous tools on genome assemblies, whose level of completion directly affects the comparability of the results across species or populations. dnaPipeTE, whose use is demonstrated here, tackles this issue by directly performing TE detection, classification, and quantification from unassembled short reads. This chapter details all the required steps to perform a comparative analysis of the TE content between two related species, starting from the installation of a recently containerized version of the program to the post-processing of the outputs.
