Create MNI-aligned grids in individual head-space
When combining the source-level estimates of activity in multiple subjects, the activity can first be interpolated on the individuals MRI (using ft_sourceinterpolate) and then spatially normalized to a template brain (using ft_volumenormalise).
It is also possible to define the source-reconstruction grid for each individual subject in such a way that all these grids are already aligned in MNI-space. The combination or statistic of source-level data across subjects can then directly be computed within the source-structure without the need to interpolate and normalize each volume.
The content of this page has moved to another location, and is dealt with in context in the tutorial about the construction of different types of source models.
