[Freesurfer] acceptable T1 input sequences

Dear all, I am a new FreeSurfer user, and have a quick question before beginning to process T1 data: on the beginners guide (entitled 'Cortical Reconstruction with FreeSurfer'), it says that the input ought to be from MPRAGE or from SPGR sequences. 1) Are these the only sequences that FreeSurfer can process? I have data obtained using a MDEFT sequence, with fat-insensitive excitation pulses and a FLASH-EPI hybrid readout. 2) Also, I only have one structural run per brain - but the tutorials / set-up pages seem to suggest that it is necessary to have 2 structural runs per brain. I would appreciate more information on the type of T1 input sequences that FreeSurfer can process. thanks, Narly.
