Changes

This release fixes a number of bugs affecting the creation of Dasha scripts for specific model-free models (two time scale motions but without the tf ''τ_f'' parameter) and the reading of Dasha results for models with motions on two time scales. The [http://www.nmr-relax.com/manual/value_write.html function value.write] which was broken when trying to write out relaxation data (R₁, R₂, or the NOE) has been fixed as well as the out of date generate_ri.py sample script.
