MddNMR is a program for processing uniformly and non-uniformly sampled (NUS or sparse) NMR spectra. Potentially any pulse sequence can be run in the NUS mode. In the NUS acquisition, only a fraction of full data set is recorded. MddNMR works by replenishing (interpolating) missing data points up to the full matrix. After that regular spectra processing with FFT, LP, etc. is applied conventionally. Besides, it can be used for decomposition of sparse (or complete) data into single (or multiple) peak components in order to estimate frequencies, amplitudes and other spectral features.

In this manual, usage of the software is described by several examples (Tutorials). In addition, complete set of parameters and formats of essential files are given in Appendix (Details). Description of underlying mathematical algorithms and processing protocols can be found in (Method) and in our papers listed (Reference) and in the materials sections/references cited therein. XML format (USF3) is used storage of processed data.
