indeed we seems to be missing explicit instructions on that, so look
into
http://www.pymvpa.org/modref/mvpa.mappers.base.html?highlight=getinid#mvpa.mappers.base.Mapper.getInId
so, for a mapped dataset ds, try:
ds.mapper.getInId(10)
e.g:
n [4]: print dataset
------> print(dataset)
Dataset / int16 1452 x 530 uniq: 12 chunks 9 labels labels_mapped
In [5]: print dataset.mapper.getInId(1)
------> print(dataset.mapper.getInId(1))
[ 0 1 17]
Thank you very much!
Now I remember that this is used in a similar way in the
eventrelated_example.py... so it seems to be documented (but users are
lazy) :-)
In [10]: coor=dataset.mapper.getInId(1)
In [11]: coor
Out[11]: array([ 0, 1, 17])
In [12]: coor_reverse=np.array([coor[2],coor[1],coor[0]])
In [13]: coor_reverse
Out[13]: array([17, 1, 0])
In 0.5 the world becomes simpler -- arbitrary feature attributes allow to embed
original coordinates from the beginning:

look for voxel_ids
Cool - this is a great improvement.
Best,
