Talairach Coordinate to VOI:
You can use this plugin to generate a spherical VOI for which you can choose the radius and the talairach coordinate.
To create multiple VOIs you can run the plugin several times with diffferent output filenames and then get all VOIs in the VOI analysis dialog (Ctrl-R) by using the Add-button instead of the Load-button.

VOI to POI:
With this plugin it is possible to convert your VOIs into POIs. A small introduction might be helpfull in order to understand how this conversion works and what the limitations are.
VOIs are a number of points (voxels) in 3D space that together form a region in a volume.
POIs are a number of points (vertices) in 3D space that together form region of interest on the surface.
So in both cases we have points with coordinates in a common 3D space, but these coordinates are not precisely coinciding.
The way the plugin works is by looking for surface coordinates that are close enough to the volume coordinates of the VOI. All surface coordinates that are within a user defined distance from any VOI coordinate are included in the corresponding POI.
The POI names and colors will be copied from the corresponding VOIs. It can of course happen that no surface points are close enough to a VOI to create a corresponding POI (e.g. for a region in the middle of the white matter). In that case the POI name will inlcude "(empty)" to let the user know the VOI was processed, but the corresponding surface region does not exist!
Before you start the plugin you should make sure that you have loaded:
1. A VMR with VOIs
2. The Corresponding Surface.
