The command lines I used is:
qiime feature-classifier classify-sklearn
--i-classifier gg-13-8-99-515-806-nb-classifier.qza
--i-reads rep-seqs-dada2.qza
--o-classification taxonomy.qza
And the error message is: There was a problem with the command:
(1/1) Invalid value for '--i-classifier': 'gg-13-8-99-515-806-nb-
classifier.qza' is not a QIIME 2 Artifact (.qza)
But I check my path and the file is in the current folder. Could you help me to figure it out?
First, what version of qiime2 are you running? Second, check your pwd and ls for the folder you’re currently in. There was a bug at one point in qiime2 where an incorrect path said there was no artifact, so its possible that if you check your path, it might be the issue.
If that doesn’t work, try dropping your gg-13-8-99-515-806-nb-classifier.qza into view.qiime2.org.
