Description
This program will synthesize a flash acquisition based on previously computed T1/PD maps
Examples
Example 1
fdir = $subjects_dir/$subj/mri/flash
mri_synthesize -w 20 30 5 $fdir/T1.mg* $fdir/PD.mg* $fdir/../orig/orig.mgh
Description: This command takes the T1 and PD volumes (they can be either 'mgh' or 'mgz' (compressed) format), and creates an optimally weighted FLASH image with TR=20ms, flip_angle=30degrees, TE=5ms. The synthetic image is written in the $subjects_dir/$subj/mri/orig directory with 'mgh' format.
