Average/Std of All open stacks

[Alex Vaughan]

Hi All,

I'd like to make a macro that will generate two stacks: the average of
all open stacks, and the stdev of all open stacks.  Stacks will be the
same size, type, etc.
The math is simple, but I'm having trouble figuring out how to act on
all open stacks - can anyone point me in the right direction?

Many Thanks,
Alex

Hi Alex,

see the macro documentation - you can loop simply through the
images.

For example:

for (i=1; i<=nImages(); i++)  {
   selectImage(i);
   if (nSlices>1) {
     print(getTitle()+" is a stack"); // or do whatever you like
   }
}
