Dear all,

I apologise for the basic questions, but something I've yet to get
accustomed to is ROI management in ImageJ.

In essence, I have an image with a particle of interest in. I segment
the foreground/background using the 'Mixture Modeling' plugin
(http://rsb.info.nih.gov/ij/plugins/mixture-modeling.html).

How do I eliminate smaller ROIs? (Or select the largest one, presuming
it's the particle I am after?)
How do I delete the background from my original image?
How do I select my particle with a bounding box and save as a new
(smaller) image?
Can I save the ROI as well for future reference?

I would then like to do some morphological analysis on the ROI.

I hope someone can point me in the right direction?

Many thanks, Andy
