Hi Troels, I had an idea and was wondering what you think about it. The idea is to update the relax wiki (http://wiki.nmr-relax.com) to have all of the text and equations for the relaxation dispersion models as currently found in the relax manual. It shouldn't be too hard to go from LaTeX to MathML, as they are related. For reference, the relevant relaxation dispersion model pages are: All data types: http://wiki.nmr-relax.com/R2eff http://wiki.nmr-relax.com/No_Rex CPMG-type data: http://wiki.nmr-relax.com/LM63 http://wiki.nmr-relax.com/LM63_3-site http://wiki.nmr-relax.com/CR72 http://wiki.nmr-relax.com/CR72_full http://wiki.nmr-relax.com/IT99 http://wiki.nmr-relax.com/TSMFK01 http://wiki.nmr-relax.com/NS_CPMG_2-site_3D http://wiki.nmr-relax.com/NS_CPMG_2-site_3D_full http://wiki.nmr-relax.com/NS_CPMG_2-site_star http://wiki.nmr-relax.com/NS_CPMG_2-site_star_full http://wiki.nmr-relax.com/NS_CPMG_2-site_expanded R1rho-type data: http://wiki.nmr-relax.com/M61 http://wiki.nmr-relax.com/M61_skew http://wiki.nmr-relax.com/DPL94 http://wiki.nmr-relax.com/TP02 http://wiki.nmr-relax.com/NS_R1rho_2-site MQ CPMG-type data: http://wiki.nmr-relax.com/MQ_NS_CPMG_2-site You will see that some pages do not exist yet, some are very basic, and some more complete (and, in the future, if the model name changes some links will be redirects). But none have equations yet. These pages might help users performing a web search to quickly find out that relax can optimise these relaxation dispersion models. What do you think? It might really help relax to come out at the top of most web searches on 'relaxation dispersion'. I do believe that the descriptions in the manual are far too short, but the text would be a good start for the wiki. Both the wiki and manual can be expanded together. On a related note, do you know a good way of handling paper references in a wiki? Is there a template for that? Cheers, Edward
