Mining for recurrent long range interactions in RNA structures reveals embedded hierarchies in network families

2018
Nucleic Acids Res
PMCID: 5934684
PMID: 29608773

[…] lows. First all canonical Watson–Crick and wobble base pairs (i.e. A-U, G-C and G-U) were identified. Then, since many structures are naturally pseudoknotted, we used the K2N () implementation in the PyCogent () Python module to remove pseudoknots. Problems arise when a nucleotide is involved in several Watson–Crick base pairs (which is geometrically not feasible), probably due to an error of the […]

Influenza A virus infection impacts systemic microbiota dynamics and causes quantitative enteric dysbiosis

2018
Microbiome
PMCID: 5763955
PMID: 29321057

[…] ples (β-diversity) and relative abundance of bacterial communities were calculated using standard QIIME workflow (core_diversity_analysis.py) with sampling depth of 200, 400, 20,000 OTUs, chosen by a PyCogent algorithm, for the lung, the small intestine, and fecal samples, respectively. Chao1 estimator [, ] and Shannon H-index [] were used to evaluate community richness through alpha diversity (Ad […]

Assessing the utility of metabarcoding for diet analyses of the omnivorous wild pig (Sus scrofa)

2017
Ecol Evol
PMCID: 5756863
PMID: 29321862
DOI: 10.1002/ece3.3638

[…] (Edgar, ) (Edgar, ) was used to create reference databases that correspond to the specific amplicon regions of the trnL and CO1 marker sequences from all downloaded GenBank (Benson et al., ) records. PyCogent (Knight et al., ) was used to extract the full taxonomic lineage using the gi‐to‐taxid mapping files provided by GenBank. All extracted amplicon regions were dereplicated to 100% sequence ide […]

A Critical Review on the Use of Support Values in Tree Viewers and Bioinformatics Toolkits

[…] en rerooting Newick trees. After reporting the issue, a previously undocumented option (–s) has been documented that permits to automatically interpret inner node labels as branch support attributes. Pycogent interprets inner node labels as support values by default and those are correctly handled by the rooting functions. […]

[…] to the OTU table. There are three steps in deciphering the enterotype of stool samples []. The first step is to calculate the distance matrix of β-diversity. R package “vegan” [] and Python software “Pycogent” [] were employed to calculate nine types of matrices, namely Alternative Gower, Bray Cutris, Jaccard, Kulczynski, Chebyshev, Pearson, Horn, Euclidean, and Weighted UniFrac. The second step i […]
