Hello Jesper,

Is there a manual for eddy_openmp that describes the optional arguments in more details?

For example, how helpful would be to use the --mb switch? My data is acquired with MB=2 and GRAPPA=2 . Do I have to add --mb 2 to eddy_openmp command line?

Thank you,

Mahmoud

Dear Michele,

this is a known problem for some acquisition schemes. The patch that was released yesterday will address this issue through the --data_is_shelled flag.
