Follow-up Comment #2, bug #22008 (project relax): If this is a restriction of only the B14 analytic CPMG model (http://wiki.nmr-relax.com/B14), it would be best if only the B14 is affected. There is no need to restrict the numeric models based on the artificial limitation of an unrelated model. Maybe the best solution would be to check if the model is B14, and if so skip odd interpolation points? _______________________________________________________ Reply to this item at: <http://gna.org/bugs/?22008> _______________________________________________ Message sent via/by Gna! http://gna.org/
