Author: tlinnet Date: Thu May 22 14:59:45 2014 New Revision: 23332 URL: http://svn.gna.org/viewcvs/relax?rev=23332&view=rev Log: Merged revisions 23331 via svnmerge from svn+ssh://tlinnet@xxxxxxxxxxx/svn/relax/trunk ........ r23331 | bugman | 2014-05-22 14:52:08 +0200 (Thu, 22 May 2014) | 10 lines Fix for all edge case 'no Rex' failures of the 'NS CPMG 2-site expanded' model. This uses the no exchange checking idea, modified to function in the relax trunk, from http://article.gmane.org/gmane.science.nmr.relax.devel/5847. This is importantly on line 1 of the function. The recently introduced set of 7 unit tests (r23327) comprehensively showing these failures now all pass. This commit is mainly for demonstration purposes. ........
