Painstakingly – slow, getting the grayscale values for each nmsq.  Here is a plot for just the CRD for one arm of a dodecamer of SP-D. I will see how it turns out and whether it will be rotatable and altered to look more like it should. I don’t know how to export this as a vector file yet. The image should be inverted (not flipped vertically… but color inverted) so that is a problem as well.
