Dear all, in the nmrpipe/com directory I have found a peCOSY.tcl that seems to be the script to create the 2D reference spectrum from the 1D spectrum mentioned...

Hello nmrpipe-group, I would like to ask you the following. I am trying to process a HMBC (1H-13C) spectrum which was acquired in the direct dimension in DQD...
Hi All, Is there an easy way to do this? Extract a 1D slice out of a 2D data and append it somewhere, then open another 2D data set and replace one of its 1D...
Hello, I've run some 2D B1 field inhomogeneity experiments on a Bruker spectrometer and am trying extract individual 1D slices of the processed spectrum as...
Pipe2txt.tcl works for 2D spectrum. But if you use it to extract data points from 1D nmrPipe file, you will see data in the first (frequency in Hz) and four...
Right, I'm using Pipe2txt.tcl on a 2D spectrum in order to extract an indirect 1D slice. The first column in the output is for the direct dimension and the...
Hi all I recently used the -zf option with ZF (to a final number of points of 148) before a Fourier transform and got strange results. I think this could be to...

Hi all I reprocessed everything and it seems I was dealing with mixed files and that the -zf option for ZF didn't cause the chemical shift differences I first...

Hi, I've recently acquired some spectra on a Bruker Avance II spectrometer. When processed at the spectrometer using Topspin the spectra have acceptably...
Did you use the convert bruker in NMRDraw ? Sometimes it gives useful suggestions. Bye, Marco ... Dr.Marco Sette, Ph.D. Department of Chemical Sciences and...

Hi Marco, Yes, I'm using nmrDraw and using the parameters as set by the macros within nmrDraw and also trying systematic variations of those parameters in an...
I've found that changing -DMX to -AMX in the default conversion script created by the bruker conversion utility greatly reduces the baseline problems in...
Hi I would like to try projection reconstruction in Varian. E.Kupce and R.Freeman, J. Amer. Chem. Soc., vol. 125, pp. 13958-13959 (2003). E.Kupce and...

Hi I would like to try nonlinear acquisition for recording 3Ds. I thus would like to get some information about how to do that in nmrPipe, if this is something...

Hi Sebastien I have been running these experiments. As much as I would love to use NMRPipe for processing (and I am sure it is possible) I ended up using...
Hi Sébastien, Most of the recent Biopack sequences are set up to do the PR method and in the sequence instructions there are tips to how to process using the...
Dear all, Our group has prepared free package of programs for non-linear acquisition, which gives output also in NmrPipe format. It is based on simple...
Hi, Thanks for that hint - works a charm for me too! Cheers, Keith Keith Cross Senior Research Fellow School of Dental Science University of Melbourne...
Hi Shaheen Thanks for the tips. I also received some other mails and the trend seems to be more on focusing on nonlinear sampling (exponential, radial, etc. +...

Hi Mike ! Thanks for the tips. For nonlinear sampling, I got other people proposing the use of the RNMRTK. Also, I would like to try the NonLinearFT from...

We occasionally use nmrDraw to look at 1-d spectra from a Bruker DMX and I see that the suggestion about setting the -AMX option in the bruk2pipe script does...
Hi all, ... Could anyone explain why? Fourier Transform is natural solution for obtaining spectra. It needs no assumptions (like assumming number of peaks),...
Hi Anna First of all, thanks for your help. A lot of people have answered this thread, which is quite exciting, this means these topics are actively developed,...

Hi, Seb, All sequences may be used for arbitrary sampling, we recommend you the semi-constant ones. What spectrometer do you use? If it's Varian's one, you can...
It's common to nonuniformly sample the constant-time dimension. In this case you want to evenly distribute the samples in the constant time period since there...
Hello All, First, in response to Anna's comment below, the DFT does make some assumptions. It assumes that the frequencies are band limited and it assumes that...
