What is RP error?

[KY]

I am using Mtex version 3.3.1. When taking difference between two ODFs using calcError, Mtex describes in the help to be using RP error as default. Can you please describe what RP error means in Mtex?

This is a bug in the documentation. When computing the error between two ODFs - odf1 and odf2 the default error is the integrated difference, i.e.

error = 0.5 * integral(abs(odf1 - odf2))

I hope this helps.

Ralf.
