When I run ./Bin/GradsPrepare *.nc, I get the *.ctl and *.coord. But the *.ctl file has something wrong(vectorpairs u,v s01u10m,s01v10m).

ga-> open Con_ATM.1985010100.nc.ctl
Scanning description file: Con_ATM.1985010100.nc.ctl
Warning: VECTORPAIRS variables u,v were not found
Warning: VECTORPAIRS variables s01u10m,s01v10m were not found
Segmentation fault (core dumped)
But If del the sentence "vectorpairs u,v s01u10m,s01v10m", I can use the Grads to plot and it is true.

So what wrong with the sencence "vectorpairs u,v s01u10m,s01v10m"?

And another thing how can I get the precipitaion rate (mm) and 3 layer soil moisture? Need I rectify the Main program?

Thank you very much!
