[gembud] sncross question

hi all,

I got a quick question about using sncross
I am trying to put some sounding files (different locations) together and plot cross section using sncross. I used sncfil to create sounding file, then used sncross. Anyhow, it doesn't work.
Anyone out there has this type of experience,  please give me a hand.

Thanks,

Sen Chiao
