Quantification of small molecules anne  2018-05-23 05:11
 

Hi,

I watched the webinar 16, which is about small molecule quantification. They showed how to get values of accuracy after building up a calibration curve, but is it also possible to visualize the values for mean, standard deviation and realtive standard deviation for replicates of each transition of one precursor within the table? I could not find it in the results grid.

Best regards,
Anne

In Skyline 4.1 we introduced a feature called the "Pivot Editor" which lets you group rows in the Document or Result grid and calculate CVs etc.

Here's the page with new 4.1 features:

And here's a PowerPoint which walks through the steps of calculating the CV of peak area across sample groups:

I think you could go through similar steps to get the information you want displayed in the Results Grid.

Hi Nick,

thank`s a lot for responding. I found the pivot editor and calculated CV`s. But I could only calculate for all Replicates. In one batch I normally work with three to five replicates per sample or calibration standard. (see in my file e.g. three replicates His1-His3) I want to group those and calculate mean area and CV´S. How can I manage that?

Is it possible to see the ratio of transtions of one precurser. I mean it is visualized in plots, but can I also see it in my result table.

Best regard,
Anne
