How to read provenance in an artifact file?

Life · December 3, 2018, 2:59pm

Hi Bod,

I downloaded .qza file, but i can not understand where i could find commands you used.Then exported classifier-dada2.qza file and get .pkl file, but i could not read it with python pickle. I think i’m doing something wrong. Сould you please explain in more detail how can i find commands within the provenance in the file.

Thank you!

Hi @Life,

To see a file's provenance:

go to https://view.qiime2.org and view the artifact there. Do not export the file — you will lose its provenance.
Click on the "provenance" tab in the upper-right side of the screen
Click on any of the boxes (representing individual commands) to see what command/parameters were used, and other info like QIIME version and system environment. You should see something like this:
