[Freesurfer] multi-echo mprage

Hi All,

I have some multi-echo mprage images from a sequence and protocol set up to emulate Andre's 2008 paper. What's are the "best-practices" for using data from this type of sequence in Freesurfer?

Related side questions: I have used the suggested morphometry protocols on the FS wiki (1mm iso resolution, same FOV, bandwidth matched, etc) 1) are people who are using this method using 4 echoes of alternating polarity, or 4 echoes of the same polarity? 2) for some subjects I have also acquired a 3D T2. Any recommendations on using these data together?

Thanks, Souheil
