[New preprint] Direction-aware functional class scoring enrichment analysis of Infinium DNA methylation data
#Genomics #Epigenetics #Bioinformatics
In this article we outline a refined method for pathway enrichment of infinium array data that is more sensitive and precise as compared to existing over-representation approaches. Feedback welcome.

My latest preprint exploring transposable element (TE) activity in the genomes of sparrows.

https://biorxiv.org/cgi/content/short/2023.10.26.564301v1

We found remarkably high levels of repeat content in the newly generated genomes of
Bell's, Song, and Savannah Sparrow. 31% of the Bell's sparrow genome is spanned by repetitive elements.
This is ~3x as much as previously reported in most songbirds.

Thanks to all my co-authors for their contributions to this project!

PhylteR: efficient identification of outlier sequences in phylogenomic datasets.

PhylteR can automatically identify sequences likely to be hidden paralogs or horizontally transferred genes in very large datasets. Removing those sequences therefore reduces noise in downstream analyses.

Available as an R package on CRAN or as docker and singularity images.

'Both genomes had been analysed before, but the fragmented assemblies had scaffold sizes comparable to the length of long reads prior to assembly. Our new assemblies illustrate how long-read technologies allow for a much better representation of species genomes. We are now able to conduct more accurate downstream assays based on more complete gene and transposable element predictions.'

Preprint from Salzberg team questioning a 2020 Nature paper from Rob Knight 😮

"the raw read counts were vastly over-estimated for nearly every bacterial species, often by a factor of 1000 or more."

"Our conclusion after re-analysis is that the near-perfect association between microbes and cancer types reported in the study is, simply put, a fiction."

Major data analysis errors invalidate cancer microbiome findings

If I were to repeat mask a bunch of genomes (closely related) would the best option still be a home made pipeline of RepeatModeler + RepeatMasker these days (basically what I did there https://doi.org/10.1101/2022.09.02.506387)?
Or is there a ready to go solution here?
i.e. give all genomes and get them back soft-masked.

#introduction
Hello everyone!
I’m an associate prof at Virginia Tech studying viral diversity. Lately my group has been focusing on giant viruses, but we are also interested in other protist viruses, and the role of viral endogenization in host genome evolution.

Recently we have been examining the strange and complex genes encoded in giant virus genomes!
https://doi.org/10.1093/femsre/fuad053


Studying some phage genes with scattered, partial alignments in varying degrees (40~+90%) of ID against closely related cousins (~93% ANI).

I'm thinking intragenic insertion/shuffling - but what kind of signals could I look for here? Common scars? Models to reference? #phage #bioinformatics #genomics


Looks interesting, Heng Li proposes a faster #BUSCO: "miniBUSCO achieves a 14-fold speedup over BUSCO. Furthermore, miniBUSCO reports a more accurate completeness of 99.6% than BUSCO’s completeness of 95.7%, which is in close agreement with the annotation completeness of 99.5% for T2T-CHM13"
