Ian,
Thanks for your note. I am still having trouble with the .m file and so am not needing the xAct way just yet. This is becoming more and more frustrating as I try to get the .m file in a shape more along your Weyl4 example. I am not wanting to whine to the list as I think that is a big waste of people's time. I do like the kranc approach and am convinced of its demonstrated utility relative to having to construct thorns from scratch. Sorry for bothering you and Eloisa about this. I do appreciate your help and do understand that your can't perform miracles...
Hi Comer,
I'm sorry to hear that you are having so much trouble! Some of this is because Kranc's error messages lack a lot of context. I suggest to adopt an incremental approach. Start from a working version of the script, and add features one-by-one. After each feature you add, see if you can generate the thorn, and even compile it. Usually when writing software, it is best not to try to do too much at once.
