This sounds dangerously like removing particles "because they don't look
good". I strongly suggest finding a way to filter the particles by
appropriate ways (see e.g.
http://www.uab.edu/researchintegrityandimages/guidelines/list.html). That
way, the particle analyzer will just take those particles into account
that you want to analyze, your image analysis will be proper, and the
summary *will* be correct.

If you cannot come up with a way to filter the images globally (i.e.
non-biased) you are entering very dangerous terrain, ethically.

Ciao,
Johannes
