Multi-channel measurement

[Hanna_SN]

Dear Image J users,



I have a very basic question concerning measuring intensity. I have  ImageJ
2.0.0-rc-8/1.49c and I would like to measure mean intensity in a roi in
multi-channel images so that each channel would be displayed in different
column in Results window. Could you please suggest me whether it is
possible and if yes how can I execute it.



Best regards,

Hanna

Here is a macro that does this:

  Stack.getDimensions(width, height, channels, slices, frames);
  row = nResults;
  for (c=1; c<= channels; c++) {
     Stack.setChannel(c);
     getStatistics(area, mean);
     setResult("C"+c+"-Mean", row, mean);
  }
  updateResults;

Instructions on how to run macros can be found at
