Regional fMRI signal coverage Web20 Aug 2011 · When smoothing images and functions using Gaussian kernels, often we have to convert a given value for the full width at the half maximum (FWHM) to the standard deviation of the filter (sigma, ). This happens because the implementation generally is in terms of sigma, while the FWHM is the more popular parameter in certain areas. bates idaho

WebThe matlab-related problem is that your script references a variable named matlabbatch without having defined it. If this is really a matlab script, and not part of a function, then you should load this variable earlier (from a .mat file) to have it in your base workspace, or construct it in some other way..
