We'd need to see you control files, but I suspect the TDEF line is
causing problems. I believe this gets set with your first open
file. For example, if you open a file and "set t 1", time will get
set to some date as defined in that control file. If the subsequent
files don't have this date defined you'll get the grid coordinate
error. You could issue a "set dfile" command to re-set the
coordinates.<br>

<div>Thanks a lot for your answer Jeff. I'm not sure how can I
give more clues about the error. There's no problem when I
work with the files separately, only when I operate between
files in a different month. I realized that there's something
wrong about the time vars. When I open consecutive files 24z,
30z, 36z, 42z... the first one has the right time value, but
the next ones shows a change of month, instead of just a 6h
advance:<br>

<div>Perhaps some more information on the specifics of the
problem would help us to troubleshoot. However, if
you're summing precip totals from a single GFS run, I
would just use templates and do the sum over different
time index values.<br>

<div>Hi everyone,<br>
<br>
</div>
I'm stucked in a problem that might be
simple to fix, maybe any of you could help
me. The point is that I can't operate with
files when there's change of month. I'm
working with GFS 0.25, and when I try to sum
the rain of the last file of month with the
rain of the first file of the moth ahead, it
returns and error like this:<br>
<br>
Invalid grid coordinates<br>
World coordinates convert to non-integer
grid coordinates<br>
Variable = apcpsfc Dimension = 3 <br>
<br>
</div>
Has any of you a solution for that? <br>
Thank you very much.<br>
</div>
