I’m getting the following error(s):
uchime file does not exist. Checking path…
[ERROR]: file does not exist. mothur requires the uchime executable.
[ERROR]: did not complete chimera.uchime.
Same for vsearch.
I’m baffled, because the mothur executable and the uchime/vsearch binaries are all in the same folder. This happens with mothur 1.39.5 and 1.42.3.
