Hi Gabriel.

We're specifically interested in getting the 3-point data (x, y, r) for the minimum bounding circle (MBC) generated by your plugin, then having the macro do a whole host of downstream functions with those parameters.

I was up until ~3am last night playing around. At first, I just opened up a dialog box so the user could enter the values manually. This works fine, but obviously limits the automation of the process. I finally came up with what appears to be a reasonable solution, in that I simply add the MBC to the ROI manager, then pulled the relevant numbers, with a few calculations, from there. Seems to work fine, but I'm sure there are better ways to do it.

Thanks for your help (& your contributions to the community).

P.S. Thanks to the other users that responded - always very good advice.

Hi,
which values do you want to retrieve? Maybe the Particles8 plugin returns
these into the ResultsTable.

CHull: Convex Hull or convex polygon calculated from pixel centres. (This
value is the same as the perimeter only for rectangular particles),
CArea: Area of the Convex Hull polygon,

and some other.

Although thinking about it, that would not work only if you are analysing the
convex disconnected components.
