Hi Jorg,
I think the Siemens tfl (MPRAGE) sequence automatically sets the TE to
the lowest possible value consistent with the choosen bandwidth,
gradient mode, and performance of your gradient set.
In all likelihood, I'm guessing that the value was still less than 4 ms
on your system, right?

Hi Jörg
T1-weighted image contrast decreases with increasing TE so you want to
minimize it. Can you really not change it at all? I've never heard of that.
Whas is the default TE?
cheers

Dear freesurfers,
currently the freesurfer single tfl protocol for the segmentation of the cortex

Unfortunately the echo-time (te) could not be set to the recomen
