Try using the expression =compound_areasum instead of =peak_area
What software (OpenLab CDS, OpenLab ChemStation, etc...) and what revision (found by going to Help>About or File>About) are you running?
The software is OpenLab CDS version 2.3.0
Thank you for the information.
The easiest way to add timed group results to a report template would be to add the Tables>Peaks and Compounds>Summed Peaks table to the template. This is a pre-built table that is setup to report results for both timed and named groups.
If you want the groups results to report in the same table as other peak results, then you will need to make sure that there are no filters on the table preventing the group results from populating. Timed groups correspond to a compound_type = 3, so check the table filters to make sure that there is not a filter for Compound_Type <> 3, and if there is then remove the filter.
Yes, I want to put the timed group (summed peaks) result in the same table, for example:
Is it possible? Thank you!
Yes, it is possible. Have you checked the filters on your results table like I mentioned in my last reply? Some tables will by default have filters applied to prevent group results from being reported. These filters will look like those in the below screenshot:
Timed groups have a compound_type of 3, so you will need to get rid of the =Compound_Type <> =3 filter if you want to report timed group results in the table.
Yes, the problem was indeed the filters applied that prevented the timed group from being reported, so kind of problem solved.
However, it does not appear the value of the (summed) area for the time group (only for the isomers individually) in the box of the report. When I tick in the data analysis to include the peaks indentified and quatify peaks individually the timed group does appear in the data analysis, but it does not appear in the box of the report. Any ideia? Thank you again.
If the "Compound used for quantitation (Main Peak)" option is checked in the Peak Filters section of your table's properties that might be what is causing the problem:
You can also play around with the Remove Duplicate Peak(s) peak filter. In older revision of the software this did not work perfectly though.
I've tried both options, but the problem seems to be in the box. When I double left-click in the (blank) gap of the area (tha was supposed to be the value of summed area) the option that is placed is "=peak_area", maybe that's the problem?
That's it! It worked for named group! Thank you very much!
One last question: what's the diference between timed and named group?
A named group is a group comprised of compounds that you have already identified in your processing method while a timed group is comprised of any integrated peak that falls within the time range in the group definition.
