The next release of cellAnalyst due in May will have one especially nice feature. The hardest part new users find about getting the best from cellAnalyst (and Pixcavator) is discovering good analysis settings - size, contrast etc. Trial and error takes too long, expecially for larger images. Now the user will have the ability to analyze a small rectangle to find the measurements of objects - cells - he is interested in and then apply these settings for the analysis of the whole image. In more detail, this is described in the wiki under Analysis Strategy.
