The Peak Picking algorithm
automatically detects peaks in any 2D data objects. Resulting peaks will
be shown in a peak table on
the peak table
tab. Peaks are also colored in the data view to show the peak areas.
Finding peaks is performed as follows:
To find peaks using the menu command, please follow the instructions
2D data object you would like to find peaks in.
From the Mathematics
menu, select the Peak Picking
(Optional) Enable Auto Detect and enter your desired amount of peaks. Proceed to step 7.
In the Mathematics
tab, adjust the find peaks parameters.
the horizontal threshold line
to a new position (Optional).
The line can be easily moved by a fixed distance using the Arrow
Up and Arrow
Down buttons in the mathematics
What is the horizontal line good for?
The horizontal line indicates the threshold for peak detection. The
minimum required intensity with respect to the data baseline is shown.
The line can be moved by drag and drop:
Move the mouse pointer close to the horizontal
Push and hold the
Move the mouse
upwards or downwards.
The line follows the movement.
The peak picking results will be automatically update
when modifying the horizontal threshold
If you manually edited the parameters or enabled auto detect click the Calculate
button to update the results.
The following parameters can be adjusted:
Please refer to the Baseline
Correction parameters for details.
