Do the GNPS website for Qemistree not works now?

[kechen1984]

hi After finished the study of Qemistree via GNPS, none of data could be available profiled by qiime viewer as above. Is the website not works now ?

Hi, I'm sorry for the late reply.

Currently, the GNPS workflow is not working. You can use the workflow in proteomics2. Please select the workflow option "QEMISTREE (release_31+qemistree-update)".

If you add metadata, make sure that the first column has the name of the files, and that the header is "sample_name". This is because Qemistree is run on Qiime2, and it will only read the metadata correctly if this is the header of the first column.

Best, Helena

Hi everyone,

I hope you can help me. I tried to run qemistree in Proteomics2 platform (as you suggested above). It runs perfectly ok (without any error). However, when I open the results tabs, there is nothing in there. I was wondering if it is still working or I am doing something wrong.

I ran FBMN independently, and then I used the output files to run Qemistree. I made sure that the metadata file matched to what you said above (for that reason I used the metadata file I got from qiime2 output from FBMN).

I attached some screens of the results I got.

Thank you so much in advance for your help.

Cheers, Eber
