<div dir="ltr"><div><br></div><div>There seems to be a bug in gmtconvert in grind. It's used to paste together</div><div>pga, pgv, etc. columns into grid.xml, rock_grid.xml, grid.xyz, and uncertainty.xml.</div>The problem is that it's used with the option "-f0x,1y" which seems to treat every column into a degree measurement. (You'd think it should only affect the<div>
first two columns, 0 and 1, which are usually latitude and longitude.)</div><div><br></div><div>The upshot of this is that, in the above output files, any pgm value above</div><div>360 gets decremented by 360, just like a degree value.</div>
<div><br></div><div>Fortunately those files are output files and not really used by any subsequent</div><div>processing, which is I think why the bug hasn't been caught (unless this is</div><div>specific to a GMT version?)</div>
<div><br></div><div>I removed the -f option from gmtconvert in grind for those four files, and that</div><div>seems to do the trick, but I'm not sure if it affects anything down the line.</div><div><div><br clear="all">
