+   abstract = {We present an evaluation of the accuracy and precision of 
relaxation rates calculated using a variety of methods, applied to data sets 
obtained for several very different protein systems. We show that common 
methods of data evaluation, such as the determination of peak heights and 
peak volumes, may be subject to bias, giving incorrect values for quantities 
such as R1 and R2. For example, one common method of peak-height 
determination, using a search routine to obtain the peak-height maximum in 
successive spectra, may be a source of significant systematic error in the 
relaxation rate. The alternative use of peak volumes or of a fixed coordinate 
position for the peak height in successive spectra gives more accurate 
results, particularly in cases where the signal/noise is low, but these 
methods have inherent problems of their own. For example, volumes are 
difficult to quantitate for overlapped peaks. We show that with any method of 
sampling the peak intensity, the choice of a 2- or 3-parameter equation to 
fit the exponential relaxation decay curves can dramatically affect both the 
accuracy and precision of the calculated relaxation rates. In general, a 
2-parameter fit of relaxation decay curves is preferable. However, for very 
low intensity peaks a 3 parameter fit may be more appropriate.},
