Hi- Does anyone know what the "host is down" error means? I issued this command to read an ascii data file maybe 50 lines long. file/var="nam,q,dcape,cape,pres" ENV_cape.dat then when I try to plot the data, it gives me the error: yes? plot/vs pres,cape **TMAP ERR: Host is down Last or next-to-last record read: ENV 1 746.328 5.024 974.400 Data set: ./ENV_cape.dat Data file: ./ENV_cape.dat I can read the file outside of Ferret, just not in Ferret. Thanks for any insight jimmyc
