Hi, I am trying to precheck my design and I get an xor error stateting that the GDS-file has non-conforming geometries. Any idea how to fix it?

The precheck tool will generate a xml file, which the log points to. The xml file can be opened using klayouts marker browser. This should point you to the location of the problem in the gds.

I don't see any reference to a xml file, and searching my folders for xml files have yielded no results as well
