This fix was successfully tested by Shannon Shields on Hera on Jan. 26, 2023.
First, GridStat was run to generate GEFS stat files under the following directories (to mimic EVS subseasonal weekly average stat output structure): atmos.20221221, atmos.20221228, atmos.20230104, atmos.20230111, atmos.20230118. A StatAnalysis_evstest.conf file was then created/run to loop over these dates and gather the stat files under the respective GEFS.20221221, GEFS.20221228, GEFS.20230104, GEFS.20230111, and GEFS.20230118 directories. Setting STAT_ANALYSIS_RUNTIME_FREQ = RUN_ONCE_PER_INIT_OR_VALID in the config file allowed the wrapper to loop over each valid time. If this is not set, then the runtime frequency setting defaults to RUN_ONCE, and the user is reminded to set STAT_ANALYSIS_RUNTIME_FREQ to override.
If LOOP_ORDER=times is set and VALID_BEG is not the same as VALID_END, then a warning message appears telling the user to set the runtime frequency:
"WARNING: LOOP_ORDER has been deprecated. Please set STAT_ANALYSIS_RUNTIME_FREQ = RUN_ONCE_PER_INIT_OR_VALID instead."
