Parkinson tutorial: Invalid value for '--i-taxonomy': './taxonomy.qza' is not a QIIME 2 Artifact (.qza)

Hi
I am attending the Qiime2 workshop (Parkinson tutorial), but I got stuck while doing the taxonomy barchart section:
I ran the first command to obtain the Output artifacts: table_2k.qza (DONE correctly I got the qza file)

here is the problem
the second command to obtain the visualization: taxa_barplot.qzv as the output, I got the following message:

(1/1) Invalid value for ‘–i-taxonomy’: ‘./taxonomy.qza’ is not a QIIME 2
** Artifact (.qza)**

I copied directly from tutorial so I do not know what happened I got this:
$ qiime taxa barplot \

–i-table ./table_2k.qza
–i-taxonomy ./taxonomy.qza
–m-metadata-file ./metadata.tsv
–o-visualization ./taxa_barplot.qzv
Usage: qiime taxa barplot [OPTIONS]

Feature table to visualize at various taxonomic
levels. [required]
–i-taxonomy ARTIFACT FeatureData[Taxonomy]
Taxonomic annotations for features in the provided

have a corresponding taxonomic annotation. Taxonomic
annotations that are not present in the feature table
will be ignored. [required]
Parameters:
–m-metadata-file METADATA…
(multiple The sample metadata.
arguments will be

Thanks in advance

Hi @Brtzabe_Atencio,

Welcome to the :qiime2: forum!

You need a \ character to wrap your commands. (This is a really common error!)

You only wrapped one like here.

So, try adding a \ after --i-table and the rest of your arguments.

Best,
Justine
