Tutorial added	Tutorial for sorting data stored as numpy to on-resonance R1rho analysis
Version 4 of relax	With the latest relax release merging in years of developments in the frame order analysis, the major number has been incremented to relax 4.
Tutorial added	Tutorial for manual regarding the relaxation dispersion auto-analysis in the GUI
Tutorial added	Tutorial for R1/R2 Relaxation curve-fitting analysis on varian recorded as fid interleaved
Matplotlib example added	Matplotlib example

%PAGE% Open MPI is a Message Passing Interface (MPI) used in relax for parallalised calculations. mpi4py OpenMPI This package provides Python bindings for the Message Passing Interface (MPI) standard. It is implemented on top of the MPI-1/2/3 specification and exposes an API which grounds on the standard MPI-2 C++ bindings. relax manual on Multi processor usage If you have OpenMPI and mpi4py installed, then you have access to Gary Thompson's multi-processor framework for MPI parallelisation. Gary has achieved near perfect scaling efficiency: https://www.nmr-relax.com/mail.gna.org/public/relax-devel/2007-05/msg00000.html Dependencies Python 2.4 to 2.7 or 3.0 to 3.4, or a recent PyPy release.
