Can you give us more information about the error that you are encountering?
If you could post the entire text of the error message including the programming call stack where it occurred that would give us more information about where the bug is and whether the mistake is in Skyline or in the PRM Conductor external tool.
For bugs in external tools, we recommend posting your question in the support board of the individual tool because then your message will be received by the tool authors.
The support board for PRM conductor is here:
https://skyline.ms/project/home/software/Skyline/tools/Support/PRM%20Conductor/begin.view
With bugs like this it is often helpful if you can send them your Skyline document.
In Skyline you can use the menu item:
File > Share
to create a .zip file containing your Skyline document and supporting files including extracted chromatograms.
Files which are less than 50MB can be attached to these support requests.
You can always upload larger files here:
