Hi Lachlan,

This is very  helpful.

Are you a researcher?

Hi Dave,

A simple for loop is what you're looking for:

for(N=0;N<roiManager("Count");N++){
   roiManager("Select",N);
   run("Copy");
   newImage("Untitled-"+N, "RGB black", 400, 400, 1);
   run("Paste");
   saveAs("Jpeg", PATH);
    close();
}

Subject: help write macro for saving each ROI in ROIManager as separate file

Hi all,

Could someone help me write a macro to save each ROI in an ROIManager as a
separate file?



Here are the variables:

TotalNumROI = this is inputted by the user, which is different for each
image that has many ROIs in it.

N = an integer: 0, 1, 2, etc., up to TotalNumofROI


Here are the core steps:

roiManager("Select", *N*); run("Copy");
newImage("Untitled-*N*", "RGB black", 400, 400, 1);
run("Paste");
saveAs("Jpeg", PATH);
close();

I want to be able to open the an image and it's ROI manager, then input the
total number of ROIs into the macro script, and run the macro such that each
ROI is saved as a separate jpeg.

How do I create a loop that changes the integer N by increments of 1 until,
and including, the last ROI is saved as a separate jpeg?

Thanks,

Dave
