There are several good tutorials for macromolecular NMR.

We particularly recommend those of Vicky Higman on both Solution and Solid State NMR, that are based on CcpNmr software.

Another good tutorial is Structure Determination of Proteins with NMR Spectroscopy by Horst Schirra. This covers from NMR spectra to structure determination, and is not tied to a particular program,

For the structure generation part, there is this tutorial from Alexandre Bonvins group in Utrecht, which uses CNS.
