something about qpGraph

[bighawkin]

i am confused about this command
qpGraph -p parfile -g graph [-o outgraph] [-d dotfile]

i want to know how i can do with -g graph . it semms to need a tree structure, but how to write the note.

From read the expamle , i see above , but i have no idea to write my own messages , the lable and edge ....

root R
label Out O

label lables populations (leaf nodes) here population is "Out" vertex is "O"

label A A
label B B
label C C
label X X
edge q R Q

edge name q R -> O

edge o R O
edge cc Q CC
edge ab Q AB
edge c CC C
##edge ca CC CA
edge a AB A
edge bb AB BB
edge b BB B
##edge ba BB BA
admix XX BB CC 70 30

XX is admixture node BB , CC ..> XX with mixing proportions .7 .3

qpGraph normalizes weights to sum to 1

edge x XX X
