This seems to be an error related to your environment variables settings. See here. Also, we had a similar issue on the rnaseq pipeline some time ago, fixed on this PR. You could try to set LANG=C or LC_COLLATE=C and see whether it works.

This should be fixed now in dev, in case you want to give it a try

Yes! Thanks for your help, I have successfully run this pipline!

OK, thanks for reporting back, then I will close the issue now, let us know if you have any further question.
