[pymvpa] How to export neighborhood relationships of NiftiDataset?

[冯璐]

Dear Matthias and Thorsten,

	Thank you for helping me~~ I have check the voxel coordinates and
MNI coordinates in FSLView, but not quite sure about it. Your words confirm
my postulation. And I'll try the codes later.
	Thank you so much.

Best wishes!

...or speaking in code

from nifti import *
ni = NiftiImage('my_data')
voxel_coords=(12,23,34)
mni_coords=ni.vx2q(voxel_coords)


Best,
