parallel's Issues

New pattern not working well for grappa3.m

Hi Mark,

I'm using your grappa3.m for my project. It works well and fast for 2x2 acceleration. However, I have data that 3x for ky and 2x for kz, when I pass this 'pattern',{[1 0 1;0 0 0;0 0 0 ;1 0 1]}' into the function, the function seemed to run, but the image result still have severe aliasing. I'm not sure how to use it well. Could you give me a hint?

Thanks for your time.
