I tried to detect chimeras with the newest version of mothur on Windows, but got this error.
mothur > chimera.vsearch(fasta=current, count=current, dereplicate=t)
[ERROR]: vsearch version found = T,. Mothur requires version v2.11.1 which is distributed with mothur’s executable or available on github https://github.com/torognes/vsearch/releases/tag/v2.11.1, please correct.
[ERROR]: did not complete chimera.vsearch.
vsearch.exe is in the same folder as mothur.exe, so I’m not sure what’s wrong.
