SP-D peak widths, heights and valley values for four dodecamers. These are the data for peak 5. (count begins with peak 1 as the N term peak and moves toward the CRD, each for trimers.

When there are peaks which are “not detected” a value of 0 was used, and data were plotted both ways, i.e. with the non-detected and eliminating the non-detected). The pattern was applied to all peaks as one dataset, and to individual dodecamers (N=4) – see bottom image.
