[Met_help] Problems running grid_stat

[John Halley Gotway]

Hi Ellen,

So it sounds like your Grid-Stat run just hangs and never actually
completes.  I took a look in the configuration file you're using and saw
that you have "n_boot_rep = 0;" which is good.  That means we won't
bootstrap the stats, which for 462116 pairs would sure take a long time.

Here's what I'd recommend though - try doing the following 2 things:
(1) Turn off the rank correlation flag.  So set "rank_corr_flag = 0;".
(2) Try just using the "FULL" domain and not using the WEST polyline.  So
set "mask_poly[] = [];"

Give that a shot and let me know if it runs OK for you.  If so, try adding
back in the WEST polyline.

Thanks,
John
