Number of identified peptides c. posterior error probability (PEP) estimates the probability of wrong assignment of a spectrum to a peptide sequence Among quantified phosphoproteins, we then considered specific phosphosites in selected target proteins, such as Cdc2, stathmin, and cofilin as analyzed by mass-spectrometry (Table 3).
From a large sample of such observations we can estimate the co-assignment probability of any set of individuals.
This model, which allows the number of subpopulations to be estimated alongside the assignment of individuals during the progression of a single Markov chain [22], has been implemented in the software STRUCTURAMA (available at http://www.structurama.org).structurama.org
The copy number of the 16S rRNA gene from each genus thus determined was in good agreement (Pearson correlations >0.90, P-value <0.01) with the relative abundance of the corresponding genus that was estimated by the assignment of 16S rRNA genes from the Roche 454 reads.
Multivariable regressions were used to estimate the effect of assignment to a roommate with a history of mental health treatment on a brief measure of stigmatizing attitudes.
Our study provides a benchmark to estimate the confidence in assignment of functions purely based on sequence similarity.
On the other hand, genes with both lower gene expression estimates and the assignment of zero values by EDASeq led to an increase in outliers on a per-gene basis in our eQTL analyses (see Additional file 1: Figure S2A), whereas CQN did a better job handling these genes (see Additional file 1: Figure S2B).
However, for technical reasons discussed in [ 20], it is better to proceed in two steps: a first run to infer K, and a second run with K fixed at the modal value to estimate the other parameters (mainly the assignment of individuals to the inferred populations).
We also applied Canonical Variates Analysis (CVA) in CVAGen6 [76], [76] to determine if we could assign specimens to morphotype based purely on the measured shape of the specimens when considering all morphotypes simultaneously, and we estimated the rate of correct assignments with a jackknife-test of assignments based on the CVA axes.
