Conversion to double from struct is not possible with bwconncomp

So have this code but it keeps giving me an error at the bwconncomp line that says, Conversion to double from struct is not possible
for l=1:256 for m=1:256 for n=1:50
if (IMG(l,m,n) > 0.001)
if (( IMG(l,m,n) > 0.001)&&(IMG(l,m,n) < 0.19))
IMG(l,m,n)=1;
else
IMG(l,m,n)=0;
end
end
end
end
end
cc = zeros(256,256,50);
IMGT = zeros(256,256);
for ii = 1:50
IMGT=IMG(:,:,ii);
cc(:,:,ii) = bwconncomp(IMGT);
end
Any idea where the problem can be?

That's not a good way to binarize if you're simply comparing to a threshold.
Explain exactly what "didn't work for me" means. Do you get an error message?

That's not going to turn it into a structure. Anyway the whole thing (triple nested for loop) can be done a lot faster simply by doing this single line
IMG = IMG > 0.001 & IMG < 0.19;
No for loops needed at all. You should learn how to write vectorized code.
