I'm interested in automating and verifying results in chiral perturbation theory (and some cousins thereof...) with Mathematica.
Thankfully, it looks like a lot of time has already been invested in the package Phi, which seems to be a really nice-looking suite of tools for just that purpose!
I've successfully installed FeynCalc using the automated installation procedure outlined on the wiki. Everything that came bundled with this installation seems to work right of the box. The notebooks I've tried in /FeynCalc/Examples work like a charm. So far so good!
Following the advice in FeynCalc/Phi/ReadMe.txt, I went to look for examples using the Phi package at
I downloaded several of the notebooks (mostly from /phi/examples/ChPT/Pions - I can provide more details if necessary).
The notebooks I've looked at do not seem to run successfully without modification, at least on my system.
After some initial debugging, my understanding is that the import/load line
is deprecated. After modifying this line to the now standard
I am able to load Phi successfully. Unfortunately, I'm unable to reproduce the saved output in the notebooks, which brings me to my question.
--> Are there other known modifications necessary to run the Phi's example notebooks with the current version of FeynCalc / FeynArts / etc ?
I'm happy to provide more details about the discrepancies I encounter when trying to reproduce results, if they would be helpful. It seems to me that the issue might be a slightly higher-level one of backward compatibility (but I am new to FeynCalc, so might be missing something painful obvious).
Maybe you have some guidance?
My system specs are:
macOS Sierra 10.12.3
