General parameters

• pw - high power 90^{o 1}H pulse at power level tpwr
• tpwr - transmitter power
• tof - transmitter offset
• sw - spectral window in Hertz
• hs - homospoil flag, if hs='y', homospoil gradient will be applied during the relaxation delay
• d1 - relaxation delay (may be subject to time limitation if hs='y')

Diffusion-specific parameters

• gzlvl1 - z PFG strength for spatial encoding
• gt1 - duration of PFG
• ledflag - flag that turns on stimulated echo, must be ledflag='y', otherwise sequence is useless
• led - longitudial encode-decode delay
• sedelay - half-echo delay (between 90^o and 180^o pulses
