12 dodecamers of SP-D: peak 6., just before the coiled coil neck peak – this peak occurs much of the time, but not 100pc.  number of missing (undetected) peaks in the area of peak 6 is shown in the line for mode… with a zero and parenthesis of the number of absences).  In several cases a dodecamer would show a peak in the area of peak 6, 100% of the time. These columns of statistics will NOT have an adjacent column of statistics (top is yellow) correlating with the values MINUS the undetected peaks (e.g. the first two and the fourth dodecamers on the second row of data have no column with a yellow header, thus all measured hexamers had peak 6 on each plot.
