Author: semor Date: Mon Jan 12 19:32:24 2009 New Revision: 8426 URL: http://svn.gna.org/viewcvs/relax?rev=8426&view=rev Log: Started to implement a function for calculating the effective transversal relaxation rate (R2eff).
Now, the good file has been modified, contrary to what happened in r8418 (which was corrected in r8420). This follows a thread at: https://mail.gna.org/public/relax-devel/2009-01/msg00067.html (Message-id: <[email protected]>) Modified: branches/relax_disp/specific_fns/relax_disp.py Modified: branches/relax_disp/specific_fns/relax_disp.py URL: http://svn.gna.org/viewcvs/relax/branches/relax_disp/specific_fns/relax_disp.py?rev=8426&r1=8425&r2=8426&view=diff ============================================================================== --- branches/relax_disp/specific_fns/relax_disp.py (original) +++ branches/relax_disp/specific_fns/relax_disp.py Mon Jan 12 19:32:24 2009 @@ -195,6 +195,22 @@ # Return the correct peak height. return results[result_index] + + + def calc_r2eff(self, exp_type='cpmg', id=None, delayT=None, int_cpmg=0, int_ref=0): + """Calculate the effective transversal relaxation rate from the peak intensities.
