Saving ResultsTable as TXT does not work from Python Script when running in headless mode

Hi guys,

I have a strange problem, where I need help. I created a python script for Fiji, which is up-to date on my Windows 10 system. The script works fine when started from Fiji itself.

When I run the script now in headless mode from the commandline i get the output below. There is no error message or something, but the TXT file is just not saved.

The respective part of the python script is shown beloe and works fine when running the script from the Fiji Script Editor, but not in headless mode. But I can still remember seen it working also in headless a while ago.

I could really need help here since I currently have no workaround to save the table otherwise yet.

# run image analysis pipeline
pastack, results = run(imagefile)

    # save the particle stack
    savepath_pastack = ExportTools.savedata(pastack, imagefile,
                                            extension=SAVEFORMAT)'Saving Processed Image to : ' + savepath_pastack)

    # save the result table as file
    rtsavelocation = AnalyzeTools.create_resultfilename(imagefile,
    results.saveAs(rtsavelocation)'Save Results to : ' + rtsavelocation)

    filesaveOK = os.path.exists(rtsavelocation)'FileCheck Result : ' + str(filesaveOK))

Hi guys,

I found it and as expected I was just too stupid… I mixed up min and max particle size for the noe-working approach. That always resulted in zero detections and therefore no results. Consequently this could not be saved.
