Hi Mark, look if are you loading the nc file with gradsNC module and using version 1.9b or higher for grads? <br>I
don't have the manual here, i will check out at the office but
'vint' i think that is station function and doesn't work with 2D grid.<br>
The grads script files are txt format you can use extension .gs to difference but not necesary to run a script.<br>
<br>
good luck.<br>

Hello all<br><br>I am new to GRADS, and I am working with files that I downloaded from the<br>NCEP reanalysis page that are in .nc format. If I type something like...<br><br>sdfopen <a href="http://shum9495.nc">shum9495.nc
</a><br>set lat 60<br>set lon 250<br>set t 1<br>d vint(1000.,shum,350)<br><br>I will get the vertically integrated water content at that point which is<br>great, but I am more interested in the spatial distribution (contour plot),
<br>so I make the lat and lon vary. So if I type<br><br>sdfopen <a href="http://shum9495.nc">shum9495.nc</a><br>set lat 50 70<br>set lon 230 250<br>set t 1<br>d vint(1000.,shum,350)<br><br>I get an error about incompatible grids, and I get the error box "this
<br>program has performed an illegal operation and will be shut down". I have<br>no idea why I don't get a contour plot, as the data I downloaded is within<br>the grid that I specify. I am sure that it is probably a very simple thing
<br>that I am totally unaware of that I am doing wrong since I am new to grads.<br><br>Also, for creating scripts, do I just type it up in notepad, and type run<br>script in the grads window? Extension is suppose to be .gs, but if you
<br>type it in notepad, it has a .txt extension.<br><br>Many thanks!<br><br>Mark<br></blockquote></div><br>
