[Gate-users] problem with online plotter

[lhj8503]

Dear users,
In the vgate, I execute the benchPET, the file "benchmarkPET.root" generated, I refered the gate manual and attempted to use the online plotter to analyse the root file, but when I type the command "/gate/output/plotter/enable" in the manual, the error "command <"/gate/output/plotter/enable> not found" appears, other commands have the errors too. I wonder if others have same experience and what's the reason? If other output format （sinogram, lmf ,etc）is better for quickly analysis ?
Thanks a lot
