If condition for registration parameter

[luiztauffer]

The values for the parameter registration are usually strings:

voluseg/voluseg/_tools/parameter_dictionary.py

Line 6 in 2c4d935

'registration': 'medium', # quality of registration: 'high', 'medium', 'low' or 'none'

So this if condition will always be satisfied, the code under else will never run:

voluseg/voluseg/_steps/step1.py

Lines 92 to 96 in 2c4d935

	if p.registration:
	save_volume(fullname_volume+ori+nii, volume, p.affine_mat)
	else:
	volume = volume.T
	save_volume(fullname_volume+ali+hdf, volume)

In which cases the else condition should run?

[mikarubi]

correct. the idea would be to pass None, which is currently done as a string for consistency.
