The Search Rectangle Group
The method for peak picking uses a moving rectangle. If a peak is to be found inside a rectangle, the difference in height between the local data maximum inside the rectangle and the data values at both rectangle ends has to be no less than the rectangle height. The height of the rectangle is the percentage, as specified in the Height text box, of the total amplitude of the data in the range (the amplitude is defined as the difference between the maximum and the minimum of the data). The width of the rectangle is the percentage, as specified in the Width text box, of the total number of points in the data range.
Generally, the smaller the Height and the Width text box values, the more peaks are likely to be found. The width should not be too small, however, since the rectangle must include at least a few points.
The Minimum Height Text Box
The minimum height is the percentage, as specified in the Minimum Height text box, of the total amplitude of the data in the range, that the peak must have, as determined relative to the minimum of the data. The smaller the Minimum Height text box value, the more peaks are likely to be found. |
