Hello all, I have several 2D and 3D data sets acquired using Bruker spectrometers in the standard uniform sampling fashion and processed with the Fast Fourier Transform as normal. I would now like to subsample the indirect dimensions of these data sets to mimic having acquired them non-uniformly. Does anyone know of a tool that can easily accomplish this? In essence, I want to feed in a sampling schedule containing a list of the indirect increments to keep and have the tool output a data set (preferably in the same Bruker ser format as the original input) containing only the data for the desired increments. I know how to do this using the 'select' command in the Rowland NMR Toolkit, but when I use RNMRTK to do this, the data is already in the specific RNMRTK format and (as far as I know) cannot be output in a format compatible with other NUS processing programs. Any ideas? For example, can this be done directly in TopSpin, or perhaps with NMRPipe? Thanks, Matthew |

Update: I ended up figuring out how to do the FID subsampling I wanted using the QMIX command in NMRPipe. The QMIX syntax is quite tedious when working with the large numbers of increments that would be common with 3D data, so I wrote a Perl script that generates the necessary NMRPipe script automatically based on whatever number of starting increments and whatever number of subsampled increments the user desires. If anyone knows of any other ways to accomplish the same task, I'd still be interested in hearing about them. Thanks, Matthew |
