  Initial Request
----------------------------------------------------------------

Hi MET Help,

I'm having a problem with pcp_combine in using the "-sum" option (or any options for that matter with the GEFS member I'm using).
I'm running an embarrassingly old version of MET right now (v6), as I'm trying to do some additional verification for a paper using the same version I ran for generating the original verification stats using WRF model output.  So hopefully my question transcends through versions of MET/METPlus.

FYI, pcp_combine works fine on hourly WRF output, but is having trouble with the 6-hourly GEFS output.

A sample command is as follows: (I have also tried simply withholding the -field entries, but same problem) pcp_combine -sum 20180301_120000 6 20180302_000000 12 ./forecast_APCP_12_modelGrid -pcpdir ./temp -field 'name="APCP"; level="A6";' -name APCP_12 -v 2

The error I'm receiving is:
DEBUG 2: Performing sum command: Init/In_Accum/Valid/Out_Accum Times = 20180301_120000/060000/20180302_000000/120000
DEBUG 2: Searching for 2 files with accumulation times of 060000 to sum to a total accumulation time of 120000.
ERROR  :
ERROR  : sum_data_files() -> Cannot find a file with a valid time of 20180302_000000 and accumulation time of 060000 matching the regular expression ".*"
ERROR  :

And the contents of my ./temp folder for summing is simply 2 different GEFS model members with only APCP 6-h accumulation fields in them:
(base):=> ll ./temp
total 112
-rw-r--r-- 1 casejl ghcc 57052 Nov 12 21:24 GEFS4_1803011200_wrfout_arw_d02.grb2f060000
-rw-r--r-- 1 casejl ghcc 54994 Nov 12 21:24 GEFS4_1803011200_wrfout_arw_d02.grb2f120000

Wgrib2 on second file that is valid at 20180302_000000:
(base):=> wgrib2 GEFS4_1803011200_wrfout_arw_d02.grb2f120000
1:0:d=2018030112:APCP:surface:6-12 hour acc fcst:ENS=+4 (base:=> wgrib2 -vt GEFS4_1803011200_wrfout_arw_d02.grb2f120000
1:0:vt=2018030200

Your help is much appreciated!!

Most Sincerely,
Jonathan
