Hi Andre, Thanks for the suggestion. I'm happy to look into it if you provide a [reproducible example](https://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) and output of `sessionInfo()`.

Sorry - no, I have only provided code examples and illustrated how to access the posteriors for plotting. My rationale is that people are always going to have to modify...

Yes, you are correct, `run_model` normalizes the tracer data so they do not need to be normalized beforehand. For details, see [lines 211-254](https://github.com/brianstock/MixSIAR/blob/master/R/run_model.R#L211) and comment on [30-38](https://github.com/brianstock/MixSIAR/blob/master/R/run_model.R#L30).

Hmm, sorry I've never actually seen that warning before, and I don't know what it means... Does it run if you use the same files but only include 1 factor...
