<br>
Thank you very, very much for all of your assistance this afternoon. Your knowledge about this stuff is very extensive and useful. I will go back and apply your suggestions and see what I can come up with. I guess that part of the solution to a problem is actually
 understanding the problem.<br>
<br>
Also, someone else on the mailing list is currently helping me through the process.<br>
<br>
Again, thank you for all of your help and have a great weekend!<br>

Originally, I was just playing around with it to get multiple variables but, clearly that has messed me up.<br>
<br>
I just used get_grib/get_inv to download only the APCP files in the GRIB2 and then ran wgrib2 sref.t15z.pgrb132.prob_3hrly.grib2 |&nbsp;grep &quot;&gt;0.25&quot; on it and got every timestep through 87hrs.<br>
</div>
</div>
</span></blockquote>
<div>Just piping the output from wgrib2 through 'grep' will not subset the files. Have a look at the wgrib2 documentation to figure out the correct syntax for extracting specific records from a grib2 file.&nbsp;</div>
<div><br>
</div>
<div>But first you must decide if you want probabilities based on 3hr, 6hr, 12hr, or 24hr &nbsp;accumulations.&nbsp;</div>
<div><br>
</div>
<div>For the sake of example, suppose you choose 6-hr accumulations.</div>
<div>You want to extract these records and put them in a separate file:&nbsp;</div>
<div>
<div style="font-family:'Times New Roman'; font-size:16px">308:20541156:d=2014060415:APCP:surface:0-6 hour acc fcst:prob &gt;0.25</div>
<div style="font-family:'Times New Roman'; font-size:16px">580:41728223:d=2014060415:APCP:surface:6-12 hour acc fcst:prob &gt;0.25</div>
<div style="font-family:'Times New Roman'; font-size:16px">892:66095269:d=2014060415:APCP:surface:12-18 hour acc fcst:prob &gt;0.25</div>
<div style="font-family:'Times New Roman'; font-size:16px">1204:91189108:d=2014060415:APCP:surface:18-24 hour acc fcst:prob &gt;0.25</div>
</div>
<div>...and so on for the remaining 6hr periods in the forecast.&nbsp;</div>
<div><br>
</div>
<div>Then you change your DSET to point to the new file you created with the subset of records, and change your TDEF to have a 6hr increment, like this:&nbsp;</div>
<div><br>
</div>
<div>&nbsp;TDEF 15 linear 15z04jun2014 6hr</div>
<div><br>
</div>
<div>Then run gribmap without the -0 (use the end of the accumulation period as the valid time) and with the -v so you can make sure that everything matches. Then if you are still having problems displaying data, you must send the following:&nbsp;</div>
<div><br>
</div>
<div>1. the descriptor file</div>
<div>2. the output from gribmap -v</div>
<div>3. the output from running wgrib2 on your subset data file</div>
<div><br>
</div>
<div>Note that the first time step (initialization time) will not have any data because your first record is valid at 6hrs past initialization. To make sure everything has worked, use 'set t 2' before displaying anything.&nbsp;</div>

This file is not the same as the one you are looking at. That file has 4980 records, and you appear to have only 7. So, how exactly did you create your subset file?&nbsp;</div>
<div><br>
</div>
<div>I ask this because the file being served by NCEP is peculiar in that is has at most 4 records that would match a given ctl entry. For clarity, I will focus on only one varible, with a descriptor file entry like this:</div>
<div>&nbsp; p3 &nbsp; 0,1,0 &nbsp; &nbsp;a1,0.25 &nbsp; &nbsp;0,1,8,1 &nbsp; &nbsp;Probability of accumulated precip above 0.25</div>
<div><br>
</div>
<div>It is easy to find the records for this variable by grepping for &quot;0.25&quot; in the wgrib2 output.&nbsp;</div>
<div><br>

<div>The last four records in this list all have the same valid time, 24hrs from initialization, and they will all MATCH the set of grib codes in the descriptor entry above, yet they are not the same thing. Record 1194 is a 3hr accumulation, record 1204 is
 a 6hr accumulation, record 1214 is a 12hr accumulation, and record 1224 is a 24hr accumulation. If more than one record MATCHES a descriptor file entry, only the final one will be entered in the index file -- in this case, you would be displaying the data
 in record 1224, the 24hr accumulation. If you ran gribmap with the -0 option (to match with the inital time in an averaging/accumulation period) you would still have four records that match the 00hr time step: records 182, 308, 590, and 1224.&nbsp;</div>
<div><br>
</div>
<div>So, some careful examination of the metadata and then subsetting of the NCEP files is required before you can be 100% certain of what you are looking at when it comes to these SREF probability forecasts. I am not surprised that g2ctl is confused.&nbsp;</div>

<div><br>

<div>Hi, Aaron --&nbsp;
<div>You don't need the alias syntax with grib data. The var1.1 syntax is just a dummy variable name that is designed to be unique to the record. You can use use &quot;p1&quot; instead of &quot;var1.1=&gt;p1&quot;.&nbsp;</div>

<div>What is the output from gribmap -v?&nbsp;</div>
