Hi @Arya,
The only fix that worked for me was downgrading kneaddata from version 0.12.0 to v 0.10.0. Other proposed fixes, including changing the read headers and bowtie2 version, did not work for me.
I hope that the developers address this issue in v0.12.0, but until then, downgrading to v0.10.0 may be helpful.
Best,
Fran
