adding to Results table zeros out the line above

[jmarks]

Hello All,
Using IJ v1.48v,  I am trying to write custom fields to the Results table, using setResult, using nResults as the current line number.

run("Set Measurements...", "redirect=None decimal=6");
setResult("Membrane area", nResults, MembraneArea );
setResult("FRET area", nResults-1, areaFRET);    // nResults is now increased by 1, so must write to previous line to stay on the same line  as the entry above.
setResult("mean FRET", nResults-1, meanFRET );
setResult("Std Dev", nResults-1, stddevFRET );
setResult("FRET Area percent", nResults-1, FRETperAreaPercent );
normFRET = FRETperAreaPercent  * meanFRET ;
setResult("Normalized FRET", nResults-1, normFRET );
updateResults() ;

Everything works fine on the first pass. For each subsequent loop, the new line gets written to the next line of Results window correctly. The problem is that the results on the line above have all been changed to zeros.

What am I doing wrong?

thanks for any suggestions!

The value returned by nResults() can change so it is better to assign the value it returns to a variable. The following example does this and it works as expected.

-wayne

  macro "Measure Area and Mean [m]" {
     List.setMeasurements;
     area = List.getValue("Area");
     mean = List.getValue("Mean");
     row = nResults;
     setResult("Area", row, area);
     setResult("Mean", row, mean);
     updateResults;
  }
