Hi,
There are a number of changes that need to be made to get the loop with the
imageCalculator to work.
Is there some reason you can't do the image calculation right after
creating your mask?
Something like the edits on your script below?
I have it closing the maskfiles and xymaskfiles after the calculation, but
that is up to you.
If you need to run the imageCalculator after creating all of your mask
files, I can probably help you figure it out.
Best,
George
XYRawFileID=getImageID();//get the ID of the image you are analyzing
waitForUser("Draw the cellular outlines with the polygon tool, press <t>.
Press the OK-button subsequently");
for (i=0 ; i<roiManager("count"); i++) {
roiManager("select", i);
run("Create Mask");
MaskFile = fileWithoutEnding + "_Mask_" + i + ".tif";
MaskFileID=getImageID();
saveAs("Tiff", resultPath + File.separator + MaskFile);
imageCalculator("AND create", MaskFileID, XYRawFileID);
XYMaskFileID=getImageID();
XYMaskFile = fileWithoutEnding + "_XY Mask_" + i + ".tif";
saveAs("Tiff", resultPath + File.separator + XYMaskFile);
selectImage(MaskFileID);
close();
selectImage(XYMaskFileID);
close();
}
