When I run julia_assignment.jl , I have a problem

[Min-Zer0]

I follow pipeline.py until the 05 step, julia_assignment.jl reports an error:
UndefVarError: g_create not defined

There seems to be a problem with line 526 of julia_assignment.jl :
'''
g = Dict((i, g_create(f, string(rsite))) for (i, f) ∈ out_counts)
'''
How do I fix it ?

When julia_assignment.jl is run at the same time, some errors will also be reported:
UndefVarError: SAM not defined
UndefVarError: GFF3 not defined

I've solved the problem by adding
'''
using XAM
using GFF3
'''
to julia_assignment.jl

But I still don't know how to solve problem : UndefVarError: g_create not defined
I hope you can solve my question. Thank you very much
