Fixed version (ground truth):

  ImagePlus[] channels=extractChannels(originalImage);
  ArrayList<ImagePlus>[] results=new ArrayList[channels.length];

    final ImagePlus channel=channels[ch].duplicate();
    channel.getImageStack().addSlice("String_Node_Str",channels[ch].getImageStack().getProcessor(channels[ch].getImageStackSize()));
    channel.getImageStack().addSlice("String_Node_Str",channels[ch].getImageStack().getProcessor(1),1);
    Calibration c=channel.getCalibration();
    c.pixelWidth=1.0 / scaleFactor[0];
    c.pixelHeight=1.0 / scaleFactor[1];
    c.pixelDepth=1.0 / scaleFactor[2];
    final ArrayList<ImagePlus> result=ImageScience.computeEigenimages(sigma,integrationScale,channel);
    final ImageStack largest=result.get(0).getImageStack();
    final ImageStack middle=result.get(1).getImageStack();
    final ImageStack smallest=result.get(2).getImageStack();
    smallest.deleteLastSlice();
    smallest.deleteSlice(1);
    middle.deleteLastSlice();
    middle.deleteSlice(1);
    largest.deleteLastSlice();
    largest.deleteSlice(1);
    results[ch].add(new ImagePlus(availableFeatures[STRUCTURE] + "String_Node_Str" + sigma+ "String_Node_Str"+ integrationScale,largest));
    results[ch].add(new ImagePlus(availableFeatures[STRUCTURE] + "String_Node_Str" + sigma+ "String_Node_Str"+ integrationScale,middle));
