Metagenomics technology and microbial community diversity analysis methods
A large number of microorganisms in nature cannot be cultivated under laboratory conditions by pure culture methods, and the technical methods of traditional microbiology limit the research on environmental microorganisms. The rapid development of high-throughput omics technology has enabled humans to have an unprecedented understanding of the complex microbial communities…
r – phyloseq: Discrepancies in otu counts before and after using tax_glom
Maybe I missed something in how tax_glom works but as I did not find any info here nor elsewhere on the web, maybe someone here can help. I do not provide data but I can on request. Here is the code highlighting the issue I have CYANO_gen <- CYANO %>%…

Using mothur toolsuite on Galaxy to analyze microbial datasets : bioinformatics
Hi all, I am using the mothur toolsuite on Galaxy to attempt to process duodenal microbiome samples in humans. The datasets I am using are paired reads generated by WGS. I am directly following this guide: training.galaxyproject.org/training-material/topics/metagenomics/tutorials/mothur-miseq-sop/tutorial.html I’m stuck on the OTU Clustering section for my data samples, specifically the…
How to pool phyloseq data?
How to pool phyloseq data? 0 @688ee615 Last seen 1 day ago United Kingdom I hope someone can help. I am trying to carry out some differential abundance analysis on some microbiome data that has come from a metabarcoding experiment using 16S illumina sequencing. I have processed my data using…
ggplot2 – Fail to plot by group on a phyloseq object generated by R package Divnet
Once you already have your phyloseq object df_family, you can use the function estimate_richness from phyloseq. You can then join the sample meta data to this data frame of alpha diversities. Finally, you can use ggplot2 directly to customize your plot accordingly, e.g. to put different sample groups (here SampleType)…
r – RC Bray function not accepting phyloseq otu_table as argument
I am using James Stegen et al’s code here to calculate an abundance-weighted raup-crick value for my 16S dataset. I load in my phyloseq object then extract the otu_table. I then use the otu_table as the spXsite argument in the function raup_crick_abundance(). My otu_table is available as a dput() below…
Issues removing unwanted taxa from phyloseq object
Hi everyone, I am currently in the process of removing unwanted taxa (Kingdom=”Eukaryota”, Family=”Mitochondria”, and Order=”Chloroplast”) from a phyloseq object I created. This phyloseq object was created using my outputs from DADA2 (OTU table, taxonomy table, and metadata file). I have saved a taxonomy table in CSV format at every…

The choice of OTUs vs. ASVs in 16S rRNA amplicon data analysis has stronger effects on diversity measures than rarefaction and OTU identity threshold
Advances in the analysis of amplicon sequence datasets have introduced a methodological shift in how research teams investigate microbial biodiversity, away from sequence identity-based clustering (producing Operational Taxonomic Units, OTUs) to denoising methods (producing amplicon sequence variants, ASVs). While denoising methods have several inherent properties that make them desirable compared…

combine OTU and tax table and replace actual sequences with OTU ids (Phyloseq/dada2)
This is to the part of the question “replace actual sequences with OTU ids (Phyloseq/dada2)?” I contacted the phyloseq/dada2 developers and based on Susan Holmes’ reply (github.com/joey711/phyloseq/issues/1030) I came up with this piece of code to replace the amplicon sequences with a numbered OTU header. Further discussion can be found…
