Similar to [[roi_wts|roi_wts]], the position of the cortical normals can be used as the orientation of the sources. Note that this option should only be used if sam_coreg has been run. Alternatively, the user can request that the orientations remain unconstrained and are solved for in the typical fashion. ROIs are specified using a target file, giving not only a centroid coordinate, but also an extent. Also, like [[roi_wts|roi_wts]], the activity from a patch of cortex is represented by a set of basis functions, likely resulting in a higher signal to noise than an analysis where the mean activity over the patch is calculated. Note that if a target file is not specified, the program will treat every voxel on the cortical surface as an individual patch. This would be very computationally intensive. Currently, weights are saved as NIFTI files, where the beamformer is only evaluated for voxels on the surface of the cortex. Future extensions of this program will utilize the GIFTI format instead.</div></td>
