Hello, I just installed the latest version of GMT on my Mac running El Capitan. (5.4.1)

I get an error when trying to calculate PQUANT with a 95 setting. I saw an old issue that said closed, but this is still happening for me.

Perhaps I don't have an environment set up properly? Everything else runs OK.

Fix issue #1102 in grdmath PQUANT

Could you show us a command of what you are doing and ideally upload the grid. if it is too big then tell us the output of grdinfo on the grid.

#2 Updated by Michael 9 months ago

Here is the grid.

I just ran:

grdmath test_grdmath.grd 95 PQUANT = test_grdmath_out.grd

The grid was created with xyz2grd.

I also ran the grdmath command on my Mac laptop and got a similar issue. Perhaps I haven't set my environment up correctly?

I run in tcsh and here is how I set it up:
  1. GMT
    setenv GMT /Applications/GMT-5.4.1.app/Contents/Resources
    setenv PATH ${PATH}:$GMT/bin
    source $GMT/share/tools/gmt_aliases.csh
