Yet, according to Mokany et al. [20], sampling to what may be deemed an insufficient soil depth to capture the majority of the roots, while not sampling the root collar or fine roots, as well as sampling with inadequate replication, are a few of the methodological pitfalls associated with sampling root biomass, and can lead to underestimation.
Five tomography models were tested, but the obtained sections show common features: paths sampling the CMB region beneath Africa and paths sampling the root of East Antarctica are anomalous.
BEAST does not require an out-group to be specified but instead samples the root position along with the rest of the nodes in the tree.

To assess how good a fit our model is to a set of samples, the root mean square error, RMS, between the model and the data was calculated.
In terms of Ra parameter, for coated cutting tool sample 1 (1CCthe, the root mean square error (RMSE) is 0.023 μm and 0.030 μm for SP and SCLM, respectively.
In terms of Ra parameter, for uncoated cutting tool sample 1 (1UCthe, the root mean square error (RMSE) is 0.053 μm and 0.070 μm for SP and SCLM, respectively.
2 SEM = Standard error of measurement obtained by multiplying the standard deviation of each domain or the total score in the entire sample by the root square of 1 minus the coefficient of reliability (-Cronbach's α).
Measurements of soil NH4+ and NO3- levels confirmed dynamic soil transformations of available N by 53 hrs when we sampled the roots for microarray analysis.
Interestingly, histograms of relative gene expression values taken from samples from the root, leaf, apex, and pollen samples of the plant showed marked differences.
