Measuring continuously through a dodecamer from one CRD of a hexamer to another (a node-rich line adjusted for the slighly bent shape of the arms) in terms of length show that over 116 molecules that there is no significant difference in each hexamer’s length (diameter).
137.47+11.4 (n=16) 136.23=10.47 (n=116) The t-value is -0.84948. The p-value is .198249. The result is not significant at p < .05.

All measures from AFM from Arroyo et al provides me a mean of about 135 nm from tip of CRD to the CRD top on the other side of the hexamer. Nice round number to use to measure distance in peaks.

First new measurements which will be the basis for the remaining 350+ molecules. Y axis is brightness values (0-255, x axis is nm) molecules are adjusted at the N term peak to half of the total 135nm mean from 349 measuremens just from Arroyo et al’s images.
