Centergram representation

The centergram representation is a superposition of the base peak profile and a line graph representation of the peak list. The line graph is a Matlab stem plot of the peak centre in the x-axis and peak maximum intensity in the y-axis. The example bellow was obtained using the CE-TOFMS urine dataset. The peak list was obtained after the following transformation

1. myFinnee = myFinnee.filterDataset(1, 'RemoveNoise:5:5:100');
2. myFinnee = myFinnee.BaselineCorrection(2);
3. myFinnee = myFinnee.filterDataset(3, 'RemoveNoise:5:5:100');
4. myFinnee = myFinnee.doCentroid(4, 'LocalMax:2:0');
5. myPeakList = PeakList(myFinnee.Datasets{5}, 100, 0.1, 5);

The centergram representation is simply obtained using

myPeakList.Centergram

or after zooming in

The superposition of the stem plot with the BPP allows to easily notice coeluting species. Using the Data cursor, individual stem line can be selected allowing to attach to the graph a datatip with key FOMs. A new figure will also pop in with the corresponding PIP.
