The Fourier transform seems to reverse the rows and columns of the data.
In the CG-SENSE reconstruction I get flipped data in rows and columns.
I think the problem is the default isign parameter of the nonuniform Fourier transform.
I get the right reconstruction when I change the default for nonuniform_fourier_transform_adjoint to isign=-1 and for nonuniform_fourier_transform_forward to isign=1.
However, given the definition of the Fourier transform, it should be the other way around.
