qCLIC & ExactMassList

Post by sennin » May 6th, 2019, 10:00 am

I want to use a CLIC expression I made for alkylbenzenes in combination with a crude template that covers my alkylbenzenes and some other groups. I then want to apply the CLIC expression to the template as a qCLIC so that it only picks up the alkylbenzenes. However, whenever I try to use an expression that contains the function "ExactMassList" as a qCLIC it will not match the blobs that should pass the qualifier. If I use the CLIC expression alone to select blobs it will highlight all of my alkylbenzene blobs, but not when used as a qCLIC.

Is it possible to use the ExactMassList as a qCLIC? It is mentioned in the User's Guide that a qCLIC can include match factors, retention bounds, and base peaks as constraints. Are these the only functions available for Qualifier CLICs?

Which version of the software are you using?

It might be related to a bug fixed in v2.7r3 and v2.8r2:

I am currently using version 2.6b0 version of GC-Image, so I have to get the latest version to make this work then. Thank you very much for pointing this out!

Another possible workaround is to replace ExactMassList with pre-calculated exact masses. Of course, it would not be as convenient as the function.

In any case, you may want to update at least to v2.6b4.
