[Neuroimaging] [Nipy-devel] [dipy] PIESNO

[Arnaud Boré]

Dear dipy experts,

I try to figure out how to use PIESNO to estimate the noise. In the example
http://nipy.org/dipy/examples_built/piesno.html#example-piesno we don't
know about the grappa factor. Is it 3 so we have N = 12 (number of coils) /
3 (grappa factor) ?

Last question if we don't use grappa then N = 12 ?

Thank you
