["sphsmooth-sess"] will smooth an analysis on the surface. The results of the analysis must have been resampled onto the sphere using ["func2sph-sess"].

The amount of smoothing is controlled by the number of smoothing steps (-smoothsteps). A single smoothing step is when each vertex is averaged with its neighbors. This will be performed iteratively as many times as specified. This is ROUGHLY equivalent to a gassian kernel with StdDev of nsmooth/(pi/2). The FWHM = 2.35*StdDev. The StdDev and FWHM are in mm. I emphasize that this is a rough equivalence; the actual StdDev will probably be a little more. |

Description
["sphsmooth-sess"] will smooth an analysis on the surface. The results of the analysis must have been resampled onto the sphere using ["func2sph-sess"]. By default, the input directory will be sph (as created by ["func2sph-sess"]). The user must supply the output directory. To access the smoothed data in subsequent calls (eg, ["isxavg-re-sess"] or ["isxavg-fe-sess"]), add -spacedir followed by the name given to the output directory.
The amount of smoothing is controlled by the number of smoothing steps (-smoothsteps). A single smoothing step is when each vertex is averaged with its neighbors. This will be performed iteratively as many times as specified. This is ROUGHLY equivalent to a gassian kernel with StdDev of nsmooth/(pi/2). The FWHM = 2.35*StdDev. The StdDev and FWHM are in mm. I emphasize that this is a rough equivalence; the actual StdDev will probably be a little more.
