how to save the data file from an histogram?

[Anthony Combessis]

Hi everyone,

I’m actually editing my first ImageJ macro and I have a little problem:

The purpose of my macro is to generate a 1000bins histogram from a 16
bit grey level image, starting from 0 and ending at 65536. Then I would
like to save the results in a file.

The first part of the macro works, IJ shows a window containing the
asked histogram. But I have to click manually on the “List” button and
save the data file. Which command do I have to write in my macro to make
IJ save the results automatically?


Thanks for your help,
best regards

Anthony

Hi Anthony,
what about something like that?:

        getHistogram(values, counts, nBins);

        d=File.open("Histogram.xls");
        print(d, "Intensity Counts");
        for (k=0; k<nBins; k++) {
                print(d, k+" "+counts[k]);
        }
        File.close(d);

You only have to direct the 'Histogram.xls' file to the folder you want.

I hope it helps. Cheers,
Carles.

Hi Carles,
getHistogram() was the key!
Thanks a lot
