Even if floats have been normalized, the SNR calcc should be correct as long as you have similarly compensated noise parameters (read noise, dark current, gain) set correspondingly. Do you have an example image that you can provide that is not working? We'd also need corresponding read noise, dark current, and gain that and been adjusted appropriately if the float files have been normalized.
