Dear all,
For those that are interested, I have found a solution for ROI closing
after run("Create Selection") and prior to Fourier shape analysis. In a
macro:
run("Create Selection"); // requires 1.37j
run("Enlarge...", "enlarge=0");
run("Fit Spline");
run("Fourier ", "fourier=8 output");
Cheers, Andy
