Steve, Thanks for your reply. I am trying to create out2 file (the interpolated data). The `outfile' is my input file, which has data on sigma levels. I just tried it again and I'm including the error messgae below:- GDFILE Grid file outfile GDOUTF Output grid file out2 GDATTIM Grid date/time 980608/1200 GVCORD Grid vertical coordinate pres GLEVEL Grid level 500 MAXGRD Maximum number of grids 1000 GAREA Graphics area asia VCOORD Vertical coordinate type PRES Parameters requested: GDFILE,GDOUTF,GDATTIM,GVCORD,GLEVEL,MAXGRD,GAREA, VCOORD. GEMPAK-GDVINT>GAREA = 15;110;25;120 GEMPAK-GDVINT>run [GEMPLT -16] NIPBND - Invalid projection bounds. [GDVINT -11] Subset region is invalid. Please let me know how I can get my data to you.
