Hi Gabriel,

It's true that the Particle Analyzer restricts the analysis to the ROIs
but it doesn't give me the data for each individual ROI.

Therefore, I can put the individual ROIs into the ROI Manager but then
have to go to Analyze - Analyze Particles.

This gives me data for each particle and only measures the particles
within the ROIs.

However, it does not give me particle results within each ROI, e.g. ROI
1 contains 2 particles, ROI 2 contains 5 particles, etc.

Cheers,

Jacqui.

Doesn't the particle analyzer already restrict the analysis to inside
the ROI?
