bad result in vcgrappa when R=3

yes, I got the same result as you. Thank you for the hint.
But why vcgrappa is so sensitive to the center line? I don't remember the paper mentioned about it...
I can't say why it's so sensitive, that's an interesting result. Do you know of any other reference VC-GRAPPA implementations that we could test against? Might also be worth attempting the experiment on real data, simulated data is not always representative of how algorithms perform on real datasets.
I will try more data later. thanks again.
There could be some other solution, i.e. generating calib data away from center. But it seems another topic than virtual coil.
