Dear Image J users,

Can someone help me to modify this macro to get pixel by pixel intensity of
a selected circular ROI in all the frames in time lapse series.This macro is
working perfectly fine for a single frame. If this can be modified for a
time lapse series, it will save lot of time running the macro for each
frame.

// list pixels values inside a selection
w=getWidth();h=getHeight();
getSelectionBounds(xmin, ymin, selwidth, selheight);
run("Create Mask");
m=newArray(w*h);
for(x=0;x<w;x++){
       for(y=0;y<h;y++){
               m[y*w+x]=getPixel(x,y);
       }
}
close(); //close mask
for(x=xmin;(x<=xmin+selwidth);x++){
       for(y=ymin;(y<=ymin+selheight);y++){
               if (m[y*w+x]!=0) print (x,y,getPixel(x,y));
       }
}

Thanks in advance,

Runa
