Gg-13-8-99-nb-classifier.qza is not a QIIME archive

[Jia (Jia Zhou)]

Hi,

I am trying to use Naive Bayes classifiers, but got the following error messages. Could you please help me to solve this error?

There is something wrong with that file, it is probably corrupted. where did gg-13-8-99-nb-classifier.qza come from? Did you make it yourself or did you download it from the pre-trained classifiers on the website? If you downloaded it, please try again — the file must have become corrupted, e.g., due to an incomplete download.

Hi, Nicholas

You are right. It works after re-download the file from the pre-trained classifiers. I tried to use the following command to download but two files would be downloaded and I got previous showed error message. It works fine when I downloaded the classifier file to my computer first.

wget
-o “gg-13-8-99-nb-classifier.qza”
“https://data.qiime2.org/2018.11/common/gg-13-8-99-nb-classifier.qza”

Thanks,

Jia
