Problem in sst plot

[Filipe]

Hello all,

I'm trying to plot sst data from ftp://polar.ncep.noaa.gov/pub/sst/ophi/ ,
but for some reason I get a white strip at longitude 0º when using nps
projection, as you can see from this pic:

When using any other projection, grads only draws from lon > 0º, as you can
see from these pics:

I don't know what I'm doing wrong, hope someone can help me. I'm using
latest grib2ctl.pl, wgrib v1.8.0.12x and grads 2.05a (I also tested v1.9 and
opengrads 2.05). I used the script http://pastebin.com/f3dc65253

Best regards.
