However, due to the variability of number of reads in different samples, it is important to adjust all samples to a common number of reads, ideally to at least 1000 reads, since both UniFrac distances were highly influenced by the number of reads.
Each sample in a study was normalized by aligning the median of each sample to a common reference.
For example, based on an observational study of a nationally representative sample of schools, a common weakness in observed science lessons was the opportunities for student sensemaking (NASEM, 2015; Weiss et al. 2003).
Pick up only one small sample of a very common and plentiful item for smaller children only, such as an orange leaf.
This is essential if we hope to contextualize the many strands of investigation, otherwise limited by virtue of selected samples, within a common denominator.
Suppose a majority of the samples contain a common metabolite A, which has ionized to N ions, then there would be N bins that are well correlated.
Both data sets used a pool of normal samples as a common baseline sample, respectively derived from human and dog samples (see Methods).
On the one hand, we recover the existence of a CpG island methylator phenotype (CIMP) with prognostic value in a subset of breast, colon and lung cancer samples, where a common subset of promoter CGIs hypomethylated in normal samples become hypermethylated.
The epidemic curve and the results of the AFLP analysis of Campylobacter positive samples suggest a common source outbreak.
Researchers and fieldworkers discussed the complexities of explaining the rationale for multiple uses of samples and data, a common feature of genomic research: " The other difficulty is when you want to talk about data access.
