how to use "-ori ti_beta2alpha"

[incredible58]

i have installed neper4.9.0.but when i use "neper -T -n 20 -ori ti_beta2alpha", it got "segment fault（core dump)".So how could I use "ti_beta2alpha" correctly? thank you

ti_beta2alpha implies parent-child orientation relations, which requires parents. So, it will work only if there is several scales:

$ neper -T -n 2::5 -ori random::ti_beta2alpha -o 2scale
