Are there any answer? Or are there any mistakes in my question? I want to make MAS NMR spectrum. But I couldnt get such a spectrum as absorption shape. How can...
In your simulation you make a 90 degree pulse between every sampling point. I believe you want to make a 90 degree pulse prior to sampling. Thomas _____ From:...
--Thank you for your replying! How is this input file? Collect or not? I couldnt get proper result. spinsys { channels 23Na nuclei 23Na quadrupole 1 2 40000...
Hi, collegues, I am a new guy in this group. I like simpson simulation very much! it is very powerful! I made the static DFS file for 23Na. the result looks...
Are there any answer? I made another script for calculating MAS NMR Please help me. spinsys { channels 23Na nuclei 23Na quadrupole 1 2 9000000 1 30 30 30 } ...
Could you be more specific about what kind of problems you are experiencing. Your input file seems correct although there are several things that will cause...
Thank you for your replying! Im just a begginer user. So I want to learn how to use simpson. But I couldnt found example for MAS NMR (simplest?). I want to...
With the direct method you need to specify how to acquire data points - this is implicit in gcompute, so in the direct method you need to make a loop over the ...
Hello, sorry by a begginer question, but I'm going to linux nowadays and my fyrst target is use SIMPSON in this sistem. So, some one have SIMPSON on fedora...
Hello, Would like to know if it's possible to minimize parameters through Simpson/Minuit, using more than one spectrum. For example: If I have three spectrums...
Is possible load three spectrums (recorded with diffrenet spinning) for minimize 6 parameters using simpson/minuit at once time ??? Thanks all Fábio...
Hi Fabio Yes, it is definitely possible. You can make a minuit procedure with the following structure proc minuit {} { global mn par set rms 0.0 for {set i 1}...
Istalling Simpson in Linux.... after ./configure I receive Cannot find GTK: Is gtk-config in path? What i have to do? Sorry by this stupid question, but I...
you need to find the gtk+1.2 development packages -they are probably no longer supplied with fedora, so try looking at rpmfind.net. Otherwise, try to download ...
Thanks Thomas by the hints... Other question about Minuit. I have followed your script to to minimize perameters using two espectrums. Below is my code. I...
Fabio, I'm not sure why your loop isn't working, but I do see a problem you will have. When I use multiple lineshapes fit simultaneously (using simplex) I have...
If you want to change the spin rate in the minuit procedure you can easily do so, but you need to do it like proc minuit {} { ... set par(spin_rate) 500 set...
Thanks Thomas and Andy, the code below seems to work. I change to direct method. FAB spinsys { nuclei 1H channels 1H shift 1 5p 13p 0.25 0 0 0 } par { ...
Hi everyone, Is it possible to switch the angle between the rotor and the laboratory frame during an experiment? I tried to switch the angle value with the...
Hi If you download the latest version of the simpson source code (1.1.2pre30) http://bionmr.chem.au.dk/download/simpson/1.1.2preXX/ I have implemented a...
Hi Thomas, Thank you for your help. Do you have the compiled version of latest version of the simpson source code? I'm using MacOs X tiger and I'm unable to...
Dear all, I am running Gentoo linux on a dual core laptop and would like to use simpson in the server mode. However I can't get it to work and wonder whether...
Hello is it possible to simulate a 2 site exchange process with the latest version of SIMPSON? I know that the answer was NO some 2 years ago, but I wonder if...
