Hello

Bumping up the thread, as I've discovered an error:
I'm using the macro sent by Tiago (thank you very much again), but there's a
difference between it's output log and ImageJ's results window:
Log says:
1/1 : Measured ROI:  168

ImageJ returns:
1    4f30perc:0008-0169-1039:DSCN9902

The two ROIs are not the same, the log always gives back a ROI number lower
by one. Easy to fix though:

I have to change row 16 of the code:
print(count++ +"/"+sample+" : Measured ROI:  "+rois[i]);

to

print(count++ +"/"+sample+" : Measured ROI:  "+rois[i]+1);

and voila! the two numbers are identical. I've double checked it, it's the
macro that prints out the wrong number, because if I measure the output ROI
manually, I get the same results as the results window returns. I know this
is only a half solution, as it only masks the problem, not really fixes it
(and tbh in science, this is unacceptable), but at least it gives back a
correct value.

Regards,
