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?

I have used the suggested morphometry protocols on the FS wiki (1mm
Hi Souheil
we usually compute the RMS across echoes and give that to recon-all as a
normal mprage. It's a reasonable (although of course not optimal) weighting
since the earlier echoes have more signal and more contrast.
For the T2s, there's a new post-hoc procedure for deformaing the surfaces
Hi Souheil
I would run the two sets of scans separately; I would expect a T2 bias in
the sample if they are run together with ones that have no T2. Perhaps see
how T2 images influence the output (maybe have a .fsgd file with T2/noT2
as two levels) to see if there are significnt differences- no?
Dear FreeSurfers,
Does anyone know if a GE implementation of MEMPR (as described in van der Kouwe
et all '08) exists anywhere?
Thanks,
Shane Kippenhan
