Hello,

I was trying to compute an Amplitude which contains pseudoscalar particles. I tried to use $LoadPhi=true and PseudoScalar class. In the Model I gave “Automatic”. I am getting an error message
“Cannot open “Automatic.mod”

Here is the line that I was trying to execute
diags = InsertFields[
   CreateTopologies[0,
    2 -> 2], {F[2, {1}], -F[2, {1}]} -> {PseudoScalar[0],
     PseudoScalar[0]}, InsertionLevel -> {Classes},
   Model -> “Automatic”];
