Error with psconvert on Example 2 Profilling

[LoboNegro79]

Description of the problem

I started using the GMTMEX on a windows computer. I start by running the examples from The GMT/MATLAB Toolbox 2017 paper. They all run as described except, for example 2 . When running the following line of code

I = gmt ('psconvert -TG -P -E300 -A', P);

I get the following error.

Full error message

psconvert [ERROR]: System call [@"C:\Program Files\gs\gs10.01.1\bin\gswin64c.exe" -q -dNOSAFER -dNOPAUSE -dBATCH -sDEVICE=bbox -DPSL_no_pagefill -dMaxBitmap=2147483647 -dUseFastColor=true "C:\Users\pdq\AppData\Local\Temp/psconvert_stream_13184.ps" 2> "./psconvert_13184c.bb"] returned error 1.
GMT: Module return with failure while executing the command
psconvert -TG -P -E300 -A
Error using gmtmex
GMT: exiting

I install the latest gs version, before I had the 9.2 version and I had the same error.

System information

• Operating system: Windows 10
• Version of GMT: GMT 6.4
• Version of GMTMex: Not sure of this, but I am assuming the latest from the GMT 6.4 version

Will have a loot into this when find some time but the easiest is to just create the postscript file on disk and pass that file name as argument to psconvert.
