Probabilistic 3D Peak Lists and Their Corresponding Spin System Indexes

 

 

 

 

ADAPT-NMR provides probabilistic 3D peak lists for all the experiments collected in 2D:

HNCO, HN(CO)CA, HNCA, HNCB, CBCA(CO)NH, and HN(CA)CO

 

The example shown here represents a portion of the CBCA(CO)NH peak list from the RI-Brazzein protein.

The first column is the 3d_peak_id that are used to link the 3D peak with its projection in 2D orthogonal and tilted planes.

w1, w2, and w3 column represent the chemical shift value for 1H, 13C, and 15N respectively.

The Probability column represents the probability that the peak is a real NMR peak vs. noise or artifact. ADAPT-NMR reports the peaks with at least 12% probability of being real; however, it does not take into account any peak with less than 25% probability in the assignment process unless no suitable peaks can be found in the 25%-100% range.

Spin_System_id represents the index of the most probable corresponding spin system. These are particularly useful for any post-processing. ADAPT-NMR Enhancer, a comprehensive visualization and edition tool for ADAPT-NMR will intensively use these attributes.
