Dear Stefano,

Looking at the code snippet it seems you are using the ROI manager and probably have to check if the ROI manager is empty and not if the Results table is empty

If (roiManager("count") > 0) {
                     ... (statement)
}

Subject: Analyze Particles: "the list is empty"

Dear All,

within a macro I need to execute "Analyze Particles..." by using a predefined size threshold (I call it "myDim") (command line = run("Analyze Particles...", "size=myDim-Infinity display exclude include add");). The macro analyzes an array of single images.

When the macro encounters an image with no particles having size > myDim (and hence the Results table is empty), the macro stops and the window appears "The list is empty". This happens even if I write a conditional statement

if (nResults > 0) {
                     ... (statement)
}

I am using ImageJ 1.49v on a PC (Windows  7, Lenovo).

I thank all that can help.


Yours
Stefano
