Hi Chung-ke. You will be fine with numpy 1.6.2, as long as you stay in the analytical models + "NS 2-site expanded" If you would like to do the numerical models, "NS 2-site 3D plus NS 2-site Star", you should try to get numpy 1.8. This is because, that numpy 1.8 can handle linear algebra in 5 di

Dear Edward and Troels, Thank you for the additional info. So it seems that although cpmg_fit has the choice to use different R20’s, current literature is still limited to the R20A = R20B assumption. I actually have a copy of Korzhnev’s paper in my computer; will certainly take a closer look. I

Dear Edward, Thank you for the thorough explanation. Yes, I now see why having the “full” models would be useful. I will try to track down the references you mentioned - I hope they are indexed in PubMed, I really have little idea on how to search for “pure” chemistry papers - and take a look a

Hi Chung-ke, The aim of relax is to support absolutely every NMR dynamics theory in existence! For the relaxation dispersion analysis section of relax, this means supporting all published models for the dispersion data, and all parametric restrictions of these models. Many of the dispersion mode

Hi Chung-ke, The only way to find out about new relax releases is the relax-announce mailing list (http://news.gmane.org/gmane.science.nmr.relax.announce). Some relax users were signed up for the freecode announcements (http://freecode.com/projects/nmr-relax), but freecode has unfortunately shut

By the way. You can start a new analysis from the old results. I would do this. 1) Upgrade relax 2) Make backup with previous data 3) Start relax in GUI 4) Start a Relaxation dispersion analysis 5) Create the pipe 6) Then go to "user functions" -> results -> read 7) Point to the file "results.b

Dear Troels and Edward, Thank you for the pointers. I was not aware that a new version was out last week, so I’ve asked the IT people to install it on our cluster. Below is the output from ‘relax -i’: [chungke@nmrc10 onc_dAUGA_MES_310K]$ relax -i relax repos

Hi Chung-ke. Can you put the information about which version of relax you use? You can in terminal do: relax -i and write it here. And then there is the question if you used data from one field or two spectrometer fields. Fitting to one field, can give problems. This is described here: """Fai

Hi Chung-ke, Welcome to the relax mailing lists! Thanks to the hard work of one of the relax developers - Troels Linnet - this long calculation time should now be much, much shorter. Have a look at the following release announcement: http://wiki.nmr-relax.com/Relax_3.3.0 For the 'CR72 full' mo

Dear all, This is my first post here, and I have a question regarding the time it takes for a relaxation dispersion clustering process to finish. I have one clustering calculation that has been running for ~ 20,000 min on a single Xeon 2.66 GHz core. The cluster consists of 13 residues being fi
