Stack Shuffler Macro

Dear List,

I wanted to shuffle images in a stack into order of severity of
pathology for later rank analysis, so I wrote a little macro to help.

I traverse the slices of the stack with [<] and [>], and decide whether
to promote [l] or demote [j] the slice to a severe position (high slice
number) or mild position (low slice number), based on a comparison
between the image of interest and its neighbours in the stack.

Sometimes I get the error "Image is Locked" and the copied data seems to
get lost - particularly when I'm operating the macro a bit too fast. Is
there a good way around that problem?

Cheers, and a slightly late Happy New Year,

Mike

run("Delete Slice");
setSlice(n);
run("Add Slice");
run("Paste");
setMetadata(name);
}

macro "Demote Slice... [j]"{
n = getSliceNumber();
if (n == 1){exit("Can't demote the first image of a stack");}
name = getMetadata;
run("Select All");
run("Copy");
run("Delete Slice");
setSlice(n-2);
run("Add Slice");
run("Paste");
setMetadata(name);
}
