Addresses #2791

[skoudoro]

Nice! Thank you for this @pcamach2!

it is missing the part to check if it is a list of int or just a int. You can look at this example:

dipy/dipy/workflows/denoise.py

Line 310 in 976217e

if isinstance(patch_radius, list) and len(patch_radius) == 1:

.

Also, it would be great if you could update the test :

dipy/dipy/workflows/tests/test_denoise.py

Line 43 in 976217e

def test_patch2self_flow():

Thank you!
