After four years of development by numerous NMR spectroscopists, the relaxation dispersion analysis in relax is finally ready for release! [Morin 2014] This support is complete and includes almost all analytic and numeric dispersion models in existence. These have been labelled as [[R2eff]], [[No Rex]], [[LM63]] [Luz and Meiboom 1963], [[LM63 3-site]] [Luz and Meiboom 1963], [[CR72]] [Carver and Richards 1972], [[IT99]] [Ishima and Torchia 1999], [[TSMFK01]] [Tollinger et al., 2001], [[NS CPMG 2-site expanded]], [[NS CPMG 2-site 3D]], [[NS CPMG 2-site star]], [[M61]] [Meiboom 1961], [[DPL94]] [Davis et al., 1994], [[TP02] [Trott and Palmer 2002]], [[TAP03]] [Trott et al., 2003], [[MP05]] [Miloushev and Palmer 2005], [[NS R1rho 2-site]], [[MQ CR72]], and [[MMQ 2-site]], mainly named after the authors and publication date. It includes support for single, zero, double, and multiple quantum CPMG data, including combined proton-heteronuclear data, and off-resonance R1rho data. An automated protocol has been developed to simplify the analysis and a GUI has been designed around this auto-analysis. Calculations have been [[OpenMPI|parallelised]] at the spin cluster and Monte Carlo simulation level for speed.
* The [[M61 skew]] R1rho-type analytic model - the Meiboom 1961 2-site equation for all time scales with pA >> pB and with parameters {R1rho', ..., pA, dw, kex} [Meiboom 1961].
* The [[DPL94]] R1rho-type analytic model - the Davis et al., 1994 2-site fast exchange equation extending the 'M61' model for off-resonance data with parameters {R1rho', ..., phi_ex, kex} [Davis et al., 1994].
* The [[TP02]] R1rho-type analytic model - the Trott and Palmer 2002 2-site equation for all time scales with pA >> pB and with parameters {R1rho', ..., pA, dw, kex}[Trott and Palmer 2002].* The [[TAP03]] R1rho-type analytic model - the Trott et al., 2003 off-resonance 2-site equation for all time scales with the weak condition pA >> pB and with parameters {R1rho', ..., pA, dw, kex}[Trott et al., 2003].* The [[MP05]] R1rho-type analytic model - the Miloushev and Palmer 2005 off-resonance 2-site equation for all time scales with parameters {R1rho', ..., pA, dw, kex}[Miloushev and Palmer 2005].
* The [[NS R1rho 2-site]] R1rho numeric model - the model for 2-site exchange using 3D magnetisation vectors with the parameters {R1rho', ..., pA, dw, kex}.
* The [[MQ CR72]] MMQ-type analytic model - the Carver and Richards 1972 2-site model for most time scales expanded for MMQ CPMG data by Korzhnev et al., 2004 with the parameters {R20, ..., pA, dw, dwH, kex}.
