Hi Meizhen,

By multi-shot, do you mean multi-echo, or is this different?
Are there multiple EPI volumes collected during each TR
and different echo times?

Hi Rick,

Thanks for your reply, I was new to this forum at that time, and I missed your reply… I’ve already figured it out by doing 3drefit.

Thanks.
