Hi W4M team,

I have this issue when running the 'batch_correction' module (v3.0.0) on usegalaxy.eu:

It is important to notice that on this specific test, I am working only with QC pool, and I have not included my samples neither the blanks. Maybe it might be an explanation of the bug?

Here are the parameters used :

My files were checked using 'Check format' tool and without any error.
My sample metadata file contain the three necessary columns: "batch","injectionOrder" and "sampleType".

Thank you for your help,
Best regards,

Thomas

Hi Thomas,
It seems to be an error from the Galaxy instance side.
Is the problem still topical (if you try to relaunch it)? I have tested the tool yesterday and it ran without problem.

Hi Mélanie.
I tried to relaunch it and the same issue occurs.
I ran another job, this time using a classical dataset (QC pool + samples) and the same error message was present.
I noticed that I always used the version 2.1.2 only in my previous experiments, and it always worked.
