Does the Analyze function in imageJ have an option for Equivalent Circular Diameter (ECD)? I know it outputs Ferret diameter by selecting shape descriptors, but I haven’t found an option for ECD. I’m trying to find the ECD for some protein particles to use along an equation for protein volume that uses ECD. I haven’t had luck finding an equation to convert from Ferret to ED (if it exists). Anyone encountered this and found a solution?
