Dear all, I have a series of 3D spectra on a protein and now I need to pick the spectra. The usual way is to move across the planes for each spectrum but this take a lot of time, and is quite boring...Is there an alternative way? It is possible, for example in HNCA, to project the spectrum on a 2D plane and pick everything? I suppose the z information is lost in this case. Alternative ways? Thanks.
