Macro Language | select all masks from ROI Manager

[Rainer M. Engel]

Hey everyone.

Playing around with selections I had difficulties selecting all masks
from ROI Manager in one step. De-selecting all is easy ;-(

I hope I haven't overlooked the obvious.

Best Regards,
Rainer

Hi Rainer,

I had to think a moment about this but assuming you don't want to use "Show All" you could use the snipped below to select all items in the ROI manager:

array1 = newArray("0");;
for (i=1;i<roiManager("count");i++){
        array1 = Array.concat(array1,i);
        Array.print(array1);
}
roiManager("select", array1);

Best wishes

Obviously after deleting the "Array.print(array1)" line

"Deselect" in the ROI Manager is the same as "select all" since all ROIs are processed if none are selected.

Hi Rainer,

This might be the answer to your question:

count=roiManager("count");
array=newArray(count);
for(i=0; i<count;i++) {
        array[i] = i;
}
roiManager("Select", array);

-----------------------------------------------------------------
A further possibility to do operations on consecutive selections using the ROI manager would be:

{
 counts=roiManager("count");

 for(i=0; i<counts; i++) {
    roiManager("Select", i);
    run("....whatever you want to do with the selected item....");
 }
}


Hope this addresses your question and helps,
Kind regards,
Jan

P.S. if my last mail reached you forget about it, I didn't read your headline properly.

Thank you Kees, Jan and Wayne.

I was already trying something like that. But I got lost and now I know
why. I missed to hit..

roiManager("Combine");

..to be able, making a "global" enlarge of that combined mask.

roiManager("Select", 0);
run("Enlarge...", "enlarge=15"); -> enlarges that mask

roiManager("Select", newArray(0,1));
´run("Enlarge...", "enlarge=15"); -> only enlarges Mask 0

Same for selections of more ROIs. I forgot/missed to combine them first
and thought the selection process itself "failed".

Thanks again.

Rainer
