==General parameters==
*'''pw''' - {{hard90|1H}} 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 <b>ledflag='y'</b>, otherwise sequence is useless
*'''led''' - longitudial encode-decode delay
*'''sedelay''' - half-echo delay (between {{90}} and {{180}} pulses
