GRtensor in Linux uses the .mapleinit file found in the user’s home directory. Only the path to the GRlibrary and the metrics need to be specified.
libname:=`/usr/local/maple12/grtensor/lib`, libname:
grOptionMetricPath := `/usr/local/maple12/grtensor/metrics`;
Just need to change the path in libname and grOptionMetricPath
Since version 11 Maple has been using a JAVA IDE which makes the GRtensor inputs to open in a pop-up window, which is very inconvenient. The best bet is to go back to the classic worksheet mode initiated by the command
xmaple -cw
