Re: Error in background subtraction plugin after upgrade _NEW ERROR

Pedro J CamelloDr Pedro J Camello
I have found again an error using BG_subtraction_form_ROI plugin in another machine with 1.51 imagej installation. The first lines of the console message are below. There are some differences with my previous error (already fixed; thanks again, Curtis).

Although for java experts this is likely a silly question I think I´ll change my macro to avoid using that plugin. I would like to know if there is any tool to determine the speed of a piece of code, since the procedure (subtract the average value of a background ROI from each frame of a 200-1000 frames stack) will be slower using the macro language.
