Tool for Subsampling Uniformly-Acquired Data to Mimic NUS Spectra

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
