Why are you using uint16 when you have a negative number?????

Anyway,...

S = -5;
Cw1=dec2bin(typecast(int16(S),'uint16'),15)
S_recovered = bin2dec(Cw1)
maxUint16 = intmax('uint16')
maxInt16 = intmax('int16')
if S_recovered > maxInt16
  S_recovered = int16(S_recovered - double(maxUint16) - 1)
end

S_recovered will be -5 as a signed 16 bit integer, which is what I assume you want.

MATLAB: 32bits save as int32

If you look at imfinfo() of the file, you can see that the headers say it is a collection of nine images with 32 bit signed integer. If it is intended to be single instead, then the metadata is wrong.

for IDX = 1 : 9
    imgint32 = imread('lh.average.CURVATURE.tif','index',IDX);
    imgsingle{IDX} = reshape(typecast(imgint32(:), 'single'), size(img32));
end
