I'm new to protein backbone assignment by NMR, and my protein is about ~37kDa (about 400 residues). We've acquired a series of triple resonance spectra: HNCA, HNCACB, HNCOCACB, HNCOCA, and HNCACO. I also have an HQCS spectrum. While I know how magnetization is transferred in the above mentioned experiment, how do I start assigning my protein? I use NMRpipe to process the spectra and Sparky for assignment.
Thanks a lot!

Have you tried using PINE-SPARKY? I haven't used it myself (I do metabolomics, not protein structures), but I've come across it a few times looking for software. It seems to help you by doing semi-automated assignments.
Hope this helps!

Also, here is a tutorial that goes through the basics, as well as whatever software that you might need.
