<br>
Here's the problem.� Your first file TDEF is:<br>
<br>
tdef 1 linear 18Z30sep2015 1mo<br>
<br>
and the second file TDEF is:<br>
<br>
tdef 1 linear 00Z01oct2015 1mo<br>
<br>
So, when you open the first file, the first time value will be set
to 1800 on Sept. 30, 2015.� The increment is define as one month
(1mo), so t=2 would presumably be 1800 Oct. 30, 2015, t=3 same for
Nov., and so on.� The combined file has:<br>
<br>
tdef 30 linear 06Z29sep2015 6hr<br>
<br>
Here, the initial time is 0600 on Sept. 29, 2015 and the increment
is 6 hours, so the next time step should be 1200 on Sept. 29.� I
suspect that your files either have too many, or too few, time
steps.� Maybe the files contain forecast information that overlaps?�
It looks like the names of the files are f066 then f072, so maybe 6
time-steps in each, which means (complete speculation here) that
they have 6 time-steps in each for a total of 36 hours?� If true,
the first file starts at 0600 Sept 29, the next file should start
1200 Sept 30?<br>

<div>As James mentioned and I suspected, doing this one
file at a time is harder than using templates. What I
would do is download all the GFS data files, then use
one single control file to open all of them. Use
templating, as described <a moz-do-not-send="true"

the control file accordingly. The last thing to do is to

I've pasted here a pair of my .ctl file

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>
