so we are talking about 0.4.x series of pymvpa (in 0.6 AKA mvpa2 voxel
indices are explicitly stored in feature attributes of a dataset): so I
guess you are looking for:
In [10]: from mvpa.tests.tests_warehouse import datasets
In [11]: datasets['3dsmall'].mapper.getInId(0)
Out[11]: array([0, 0, 1])
?
