The person behind this is really Björn Grüning at the University of Freiburg. I am immensely thankful for the work he has put into this. Our intention to make sure that both the Galaxy version and the bioconda version are maintained in parallel to the one on this website, and continuously up to date!
Mattias de Hollander at the Netherlands Institute of Ecology kindly informed me that they recently added the ITSx 1.1b version to the Bioconda package manager. This will make it easy for Conda users to install ITSx automatically into their systems and pipelines and also for others who are using conda. The Bioconda version can be found here. I would like to thank Mattias for this initiative and hope that the Bioconda version of ITSx will find much use!
