It seems likely that one of the reasons that the tiny peaks on either side of the N termini junction of a surfactant protein D dodecamer when employing signal processing is that with the enormity of the N termini peak the requirements for an adjacent peak are too great.  I think in some kinds of image processing this might also be a factor, maybe those which “sharpen” in particular, but it surely must happen in some comperable fashion.  I really noticed it more in the signal processing algorithms than image processing.

Also missing is the splitting of the N termini junction peak into two (sometimes with a very small peak in the center) using the signal processing algorhythms. Maybe for similar reasons.

It is a little distressing to watch the signal processing algorithms continually pass over a peak that I have seen many times in many molecules, and then say there are 4 peaks in a short span ot distance where there are literally “no peaks to be seen”.
