Hi Diego,

I didn't get that error message at all.

So when you were trying to follow the beginning of this doc that starts with the X!Tandem Peptide Search:

https://www.labkey.org/home/Documentation/wiki-page.view?name=describeAndSearch

Did you setup the Pipeline Root Override as well as described here?

https://www.labkey.org/home/Documentation/wiki-page.view?name=setupCPASDemo

The section called "Set Up the Pipeline" at the end should be setup so you have a proper pipeline root to use.

Regards,

Jon
