Anatomical spatial: 3dFWHMx ValueError

[sgiavasis]

A QAP user was getting this error when running anatomical spatial:

ValueError: operands could not be broadcast together with shapes (8,) (4,)
Interface Function failed to run.

He proposed this fix in spatial_qc.py, as 3dFWHMx now produces 8 values instead of 4:

vals_full = np.array(retcode.split(), dtype=np.float)
ind_pos = np.array([4,5,6,7])
vals = vals_full[ind_pos]
