I’ve been trying to run an example of Chiral perturbation theory
calculation. The notebook is from the PHI examples website
(http://www.feyncalc.org/phi/examples). The notebook is titled
PiN.nb. Every time I run the notebook, the “InsertFields” command
throws up an error the says

loading generic model file $Failed
Get: $Failed is not a string, SocketObject, InputStream[], or OutputStream[].
$Aborted

I’ve tried changing “Nucleon[0,j1]” etc to “Nucleon[0,{j1}]” etc. I’ve also tried removing “Model->“Automatic”,GenericModel->“Automatic””.
Please help!
