Dear Vinko,

A paper was published last year in Cytometry Part A giving algorithms and
metrics for evaluating a cell sorting service, this might be very useful
for you.

Petrunkina, A : 'Algorithm and metrics for a Standardized Evaluation of
Cell Sorting Service Delivery'.  Cytometry  Part A: Vol 83A, 7, 602-607

I can email you a PDF copy if you can't get hold of one.

Best Wishes
