[Ifeffit] Ratio of peak amplitudes in R-space

[Christopher Patridge]

Jatin,

If these changes are systematic and you somewhat understand the physical or
chemical process associated with the sample,  then why not just build a
model and do a structural fitting?    A simple peak ratio comparison maybe
helpful but a much stronger argument and interpretation can be made if you
use a structural model to extract these comparisons....

several methods for building a model are available.

buena salud,

Chris Patridge
