Hi there,

Scenario: TPH run with no clean-up, in the result run we observe humics and fatty acids.

Issue: Using the template to cover all C8-C40, we are considering undesired hydrocarbons.

Can we subtract a region from a template? Or we need to create a new template and manually subtract main template from the region with humics and fatty acids?

Thank you for the help,

Depending on how undesired compounds mix with others, you may be able to add a polygon to subdivide the region or exclude the blobs of these compounds.
