One more question about CC-s. I want to create a cc, that checks if the given compound is below it's specification limit or not, less than LOQ and etc... with named compound it works like a charm, i give all the required parameters in compound CFs, but for the unknowns it does not work. I've created a timed group for them (peaks calculated individually), but the OL can not use the values given to the unknown group. What is the solution? Right now, i use the sample_label for adding extra parameters for the whole seq, like loq for unkowns.. but it's not so elegant. Any idea?
