I have around 30 images and use ImageJ macros to analyse the particles (area, circularity, etc.) in the batch. From the macros script that I'm using, I'm not able to save the results separately, I mean one results.csv file per image. Script:
fileName = getTitle();
run("Set Scale...", "distance=231 known=200 unit=um");
//setTool("rectangle");
run("Select All");
makeRectangle(0, 0, 2560, 1856);
run("Crop");
run("8-bit");
setAutoThreshold("Default");
run("Threshold...");
setThreshold(0, 116);
setOption("BlackBackground", false);
run("Convert to Mask");
//run("Close");
run("Analyze Particles...", "size=80-Infinity display exclude summarize add");
selectWindow("Results"); //activate results table
saveAs("Results", "C:/folder/Results.csv");
