Was anyone ever able to find a solution to this issue? I think I am experiencing a similar problem using gradsnc v1.9b4. I have a 13MB netCDF file (samples can be found here, <a href="http://www.cdc.noaa.gov/cgi-bin/db_search/DBListFiles.pl?did=34&tid=20349&vid=1246">http://www.cdc.noaa.gov/cgi-bin/db_search/DBListFiles.pl?did=34&tid=20349&vid=1246</a>) which contains Reanalysis rainfall rate data.<br>
<br>My script - based off of a script I found in the list archives - attempts to loop over all points in the file for all timesteps (366) and at each point (192x94) it will write ASCII output to a file. If I run it for less than 4 timesteps it works like a charm but if I set it to use 4 or more timesteps it will always fail on the 4th one at point 161,69 running the command to display the value. My first instinct was that the data at that particular point/time was somehow corrupted but subsequent tests showed that it doesn't matter what timestep I start at it will always fail the 4th time through at that exact X,Y.<br>
<br>Anyone have any ideas about what the issue might be? Thanks in advance.<br><br>Cheers,<br>Matt<br><br><div class="gmail_quote">On Tue, Apr 1, 2008 at 3:02 AM, Steven Weiss <<a href="mailto:sweiss@iafrica.com">sweiss@iafrica.com</a>> wrote:<br>
