Detailed Description

Class to identify noise region and compute noise SD in spectra. Uses average magnitude spectrum to first identify region with smallest SD. This region is likely to be noise rather than signal. Once the region is defined, the noise SD is computed as an average value of noise SD computed at each voxel over the identified frequency range.
