I would like to create working shaped pulse files in one step starting from mathematical expressions - one for amplitude, another for phase vs. time. Does anyone know software that can do it? |

For Varian systems you can use Pbox to create the shaped pulse. This can be done in a variety of ways,form using cursors on the screen, to macros, to integrating in the sequence, to using a shell to create the shape. Pbox uses basic mathematical equations but they integrated in the compiled program. You can specify a set of fourier coefficients and Pbox will produce the shape. So if you can characterize your new shape by a set of fourier coefficients you can do it with Pbox. -George Gray NMR Applications Lab Varian, Inc. |

Doesn't Bruker's Topspin 2.1 pl4 have an option for this in the shapetool? Bernie, Thanks. Does it? I can't check. If it does - could you be more specific? - Evgeny Fadeev (Aug 15 '09 at 22:06) Evgeny, Try the command 'stdisp'. I don't know if you can put in a direct math formula, but there is an included manual with the TopSpin distribution that might be worth a look! - TJCarruthers (Apr 11 '11 at 23:12) |

Hi, Here is an article, maybe contact the authors: http://www.springerlink.com/content/avdb1q1xbpp0gdqv/ Genetic Programming Optimisation of Nuclear Magnetic Resonance Pulse Shapes Or contact Magnus: http://www.bpc.lu.se/qsim |
