T-lex: automatic assessment of the presence of individual transposable elements using next generation sequence data

Anna-Sophie Fiston-Lavier and Josefa González (with the participation of a summer student Matthew Carrigan and Dmitri) have just published a very powerful and easy to use tool for the assessment of presence/absence of known TEs in the new resequenced genomes. The paper was published in Nucleic Acids Research (with the open access option) and we hope that people will find it helpful. This tool, which we called T-lex (T for transposable element and -lex for Solexa), obviates the need to run thousands of PCR in order to study population genetics of TEs and, more specifically for us, to find TEs that are likely to be adaptive. Anna-Sophie is working now on a new module for this program that would also allow us to detect new TE insertions in the nextgen data. Together these two programs (in conjunction with several other similar programs that are becoming available now) will revolutionize the TE research for us. To read more about T-lex or to use it please go to Note that you can run T-lex (or other scripts) on a cloud using the next-generation cloud service. We are in the process of creating the T-lex ScaleGenomics app so that you can run T-lex without any installation hassles.

Please give us feedback about T-lex by leaving comments here!
