[pymvpa] Concatenate datasets

[Chris Johnson]

I have multiple nifti files I want to combine into one dataset. I
think I have figured out how to do this, and I just want to verify:

e.g. If I want to drop the first two volumes in images 5-12, but
concatenate the remainder of the volumes, I would do:

dss = [fmri_dataset('%03d/fmc.nii.gz' % i) for i in range(5,13)]
ds = dss[0][2:]
for ds_ in dss[1:]:
    ds.append(ds_[2:])

Cheers,
