Error message help

[Mariana_Gomes]

I’m getting a error message while trying to use Qiime2 and I don’t know how to fix it. I get this message:

Error in read_qza(tree, tmp = tmp) : Input artifact (rooted-tree.qza) not found. Please check path and/or use list.files() to see files in current working directory.

Hi @Mariana_Gomes,

Welcome to the forum!

If you break down the error message, you'll see you get two parts. The first part is the problem:

Error in read_qza(tree, tmp = tmp) : Input artifact (rooted-tree.qza) not found.

The rooted-tree.qza file cannot be found at that path.

The second part is a suggested fix:

Please check path and/or use list.files() to see files in current working directory.

Solution: make sure you're in the right directory and check the files that are there for the rooted-tree.qza file.

My guess is you're not pointing to the correct file from R. Try the full path.

Best,
Justine
