    Hi everyone!

    Is it possible to quantify the intensity of a specific peak in 2 different ROI and do statistics like is possible with the MarkerView?
    In Biomap I found an option called Statistics but I don´t know what you actually see in the histograms. What is the parameter N? Does it represent the different pixel/positions in that ROI?

    I believe the value N corresponds to the m/z. I’ve noticed there may be an error between the value N in the image pane and the statistics pane. It seems the stats pane should be N+1 of the image pane.

    Based on what I observed, N depends on the bin size and your mass range. For example when you convert your raw data files to an image, if your mass range is from 200-400 Da and your bin size is 0.1, then N=1 means m/z is 200, N=2 means m/z is 200.1, N=3 means m/z is 200.2 and …

    Basically its the number of Data points
