Hello all,

I am trying to train the QIIME classifier as mentioned in the Q2-ITSxpress tutorial.

I am using the following command on the server:

qiime feature-classifier fit-classifier-naive-bayes \

--i-reference-reads unite.qza
--i-reference-taxonomy unite-taxonomy.qza
--o-classifier classifier.qza

And I am getting the following error:

Traceback (most recent call last):

I will be very grateful for any help regarding this.

Good afternoon!

Thank you for posting that detailed log file. Let me see how I can help.

This is the main error:

and I think that has to do with this:

Looks like your account on the server does not have access to open up the classifier.qza file. Whoever set up Qiime on this server can give your account access to this file so that the command will run.

Alternatively, you could use this tutorial to install qiime yourself (so that you own all the files and don't have any issues!)

Let me know if this works for you!
Colin
