"lb -1" (The more negative lb - the more resolution enhancement)
"gb 0.4" (gb is a value between 0 and 1. The larger the number, the more resolution enhancement)
"gm" (This command calculates the Gaussian weighted FID)
"ft" (This command carries out the Fourier transform)
"apk" (This command calculates the proper phase correction. You may have to phase the spectrum manually)
Try it on your own data with different values of "lb" and "gb" to get a feel for what it can do for you.
