Hi,

are numO5open1 and numO5open2 the same as
line1 and line2 ?

With the development version this

line1 = (GSD[l] + m).GAD[\[Mu]].(GSD[l]

• GSD[p] - GSD[k] +
      m).GAD[\[Nu]].(GSD[l] + GSD[p] + m)
  line2 = (GSD[l] + m).GAD[\[Nu]].(GSD[l]
• GSD[k] +
      m).GAD[\[Mu]].(GSD[l] + GSD[p] + m)
  denom1 = FAD[{l, m}, {-k + l + p, m}, {l + p, m}]
  denom2 = FAD[{l, m}, {k + l, m}, {l + p, m}]

OneLoop[l, line1 denom1 + line2 denom2]

works, although I’m not sure if this is your original example.

Cheers,
Vladyslav
