[gradsusr] how to use vint function in GrADS

[sushant puranik]

Hi
I am trying to find vertical integral in GrADS using "vint" command. For
that purpose i opened vwnd and specific humidity file as first and second
respectively. The q file command for both the variable are as

ga-> q file
File 1 : mean daily NMC reanalysis (2008)
  Descriptor: /home/Sushant/Desktop/10may08v.nc
  Binary: /home/Sushant/Desktop/10may08v.nc
  Type = Gridded
  Xsize = 29  Ysize = 25  Zsize = 8  Tsize = 1
  Number of Variables = 1
    vwnd 8 -999 mean Daily V wind

ga-> q file 2
File 2 : mean daily NMC reanalysis (2008)
  Descriptor: /home/Sushant/Desktop/10may08q.nc
  Binary: /home/Sushant/Desktop/10may08q.nc
  Type = Gridded
  Xsize = 29  Ysize = 25  Zsize = 8  Tsize = 1
  Number of Variables = 1
    shum 8 -999 mean Daily specific humidity

after this i used

ga->  d vint(1000,vwnd*shum.2,400)
gxstart=0, gxstop=29, gystart=0, gystop=25.
gzstart=0, gzstop=1, gtstart=0, gtstop=1.
gxstart=0, gxstop=29, gystart=0, gystop=25.
gzstart=0, gzstop=1, gtstart=0, gtstop=1.
Error from VINT:  Incompatible grids.
Contouring: -0 to 2.4e+36 interval 3e+35
Segmentation fault

after showing this message, the grads window gets closed.

Can anyone has solution for this perticular problem.

Thanks in advance
