MeanI = find(( s.MeanIntensity>154) & (s.MeanIntensity <243 ) & (s.Perimeter>100) & (s.Area>500));

[Stephen23]

Most likely s is a non-scalar structure, and so s.MeanIntensity is a comma separated list.

Tell us what this prints:

 size(s.MeanIntensity)

MeanI = find(( [s.MeanIntensity]>154) & ([s.MeanIntensity] <243 ) & ([s.Perimeter]>100) & ([s.Area]>500));

Could be using bwpropfilt() though.
