rotation in bones

Description

hi! first excuse my english. I have the problem with rotations bones. I am make exercises create bones, but if a reference point has a negative value in the Z axis, the bone creates a rotation. How I can correct this rotation? this is code:
refPoint05 = point pos:[0,0,65] size:3 wirecolor:[246,255,0] name:"refPoint05"
refPoint04 = point pos:[0,0,60] size:3 wirecolor:[246,255,0] name:"refPoint04"
refPoint03 = point pos:[0,0,40] size:3 wirecolor:[246,255,0] name:"refPoint03"
refPoint02 = point pos:[0,-1,20] size:3 wirecolor:[246,255,0] name:"refPoint02" --- negative value
refPoint01 = point pos:[0,0,0] size:3 wirecolor:[246,255,0] name:"refPoint01"
refArray = #(refPoint01,refPoint02,refPoint03,refPoint04,refPoint05)

bonesArray = #()
for i = 1 to 4 do
(
b = boneSys.createBone refArray[i].pos refArray[i+1].pos refArray[i].Transform[3]
append bonesArray b
if i>1 then b.parent=bonesArray[i-1]
b.frontfin=true
b.name = uniquename "Bone"
)

many thanks, I was going crazy. I owe you a beer, when you come to Sevilla : D

Change this:
b = boneSys.createBone refArray[i].pos refArray[i+1].pos refArray[i].Transform[3]

into this:
b = boneSys.createBone refArray[i].pos refArray[i+1].pos refArray[i].Transform[1]

Actually, the third argument on 'createBone'is the upnode axis of the bone, so it does not make sense that you set it to be the axis that points towards the next one but the perpendicullar one.

Hope it helps...
