Hi, I am interested to do an ideal pulse on the central transition of a nuclei with half integer spin. Since this is not implemeted, I was wondering if I could...
Hi, Can someone give me an example of how to use the new matrixoper command? In particular, may it be used to add two matrices together? Thank you. Robin...
Dear all, I have compiled the new version of simpson for macintosh. As Andy I had problems compiling simplot so I took his old version which works after a...
Dear Thomas, I'm afraid these instructions have no use at all for a MacOSX user. Are you actually using a Mac? In this case, you have to give detailed...
Dear Mac users, Yes, I actually did use a macintosh - but my approach is rather unix-like I realize after Malcolm's mail. Here are more detailed instructions...
Do all of you still get malloc errors? I poked around some today and found that if I comment out the last 3 lines of the readsys function in readsys.c the...
Hello Thomas, after following your instructions, I get the following error messages: [Malcolm-Levitts-Computer:~/Desktop/simpson-1.1.2pre1] mhl% simpson...
Dear Malcolm, It appears as though simpson is looking for the files you put in /usr/ local/lib in /usr/lib The easiest way to fix this should be do the...
Hi, We are trying to use method=gcompute with the REDOR simulation, and get the error that the "acq command can only be used when method is direct". We are...
You don't need the acq command. And you can find an example in the Example 1 in the "simpson" PDF file. Yefeng ... Hi, We are trying to use method=gcompute...
You cannot use g-compute to simulate REDOR spectra since gcompute is only applicable for sequences which are synchronous with the rotor period - and REDOR has...
Hi, I've contacted Dr.Jorn Schmedt and could succesfully do the simulation of R sequnces(18(5_2)and (17_1)) using Simpson. Thank you very much for the...
Hi I am trying to simulate magnetization buildup curves, and the program works when I use ideal pulses, but when I try to use real pulses, simpson gives me an...
Your second propagator isn't rotor synchronous. The duration should be n*tr. I think it should look like that: reset delay $tr22 pulse $t180 0 x $rf x delay...
Thanks a lot! It works! I got two other problems: 1) For the assymetry parameter of the quadrupole, is it right to set like {quadrupole_1_assym 0.0 0.01...
On some points the documentation on SIMPSON and SIMMOL is still not so good. But I can help you regarding passing spinsystem modifications to fsimpson. The...
sir/Madam, I have a small doubt regarding calculation of propagators using direct method in pulse sequence under MAS. When i use direct method in simple 1-d...
My immediate response is that this can't be true - at least I have never experienced any problems with the parser of the par section. If you post your ...
Sir, There may be silly problem in these two progrmas(LISTED BELOW) which i am not understanding. So i want to clarify that problem. Thank you sir, regards ...
Dear Users, 1) I have problem with fit procedure on amd64 (opteron)under linux64 (gentoo). Compilation run without any problems, simpson seems to work fine (...
Your two input files differ in powder averaging. Exc.1 uses ONE gamma_angle since you commented out the line specifying another value for gamma_angles. In...
