Dear everyone, I am the beginner of GMT, and have trouble with connceting the remote data from the data server.
Specificlly,I usually run my code,it goes nothing:
gmt begin chinaterr pdf
gmt grdimage @earth_relief_30m -JM10c -R70/138/13/56 -Ba10f5g10
gmt end show
every scripts with @xxxx ,it does not work

Need more info. Error messages? File created?

It would be possible that you need a proxy? If so, see Remote data set and proxy

there is no error or warning displayed,just run and nothing appeared,and thank you all!

Please add -Vd and post the full output listing.
