4.2 Point set selection

Figure 6 Point set selection dialog

The point set includes the brain locations that are used as a source space in the calculations and the parameters of the conductor model used in the forward cal- culations. Each point set is related with a certain BEM model (p. 8) and a cer- tain subject.

From the Point set dialog you can select an existing set from the list and accept it by pressing the [OK] button. After this you can proceed by making the full calculation (p. 11).

You can create a new point set by pressing the [Add new] button and setting appropriate values to the properties of the point set. If you modify the Origin, Lattice, or Min dist properties, the point set is recalculated and the number of points is show. If you accept the new point set by pressing the OK button, it will take a while to calculate the projection from the point set to the BEM. You can remove the point sets by pressing the [Delete] button. If several people are using the point set, it will be deleted only when it is deleted by all its users.
