[Gate-users] Question

[Michael]

Dears Gaters:
I met a problem.
According to the UserGuide, I need install a visualization tool first.
So I creat a macro named 'test.mac' including the following commands:

#  V I S U A L I Z A T I O N
/vis/open OGLSX
/vis/viewer/reset
/vis/viewer/set/viewpointThetaPhi 60 60
/vis/viewer/zoom 1
/vis/viewer/set/style surface
/vis/drawVolume
/tracking/storeTrajectory 1
/vis/scene/endOfEventAction accumulate
/vis/viewer/update

Then I type the command " /control/execute test.mac" in Gate.
It comes to an error as follow:

Idle> /control/execute test.mac                   
parameter value is not listed in the candidate List.
***** Illegal parameter (0) </vis/open OGLSX> *****
***** Batch is interrupted!! *****

What happened?
Please give some advice.
Thank you !!!
