#bioinformatics people:

What tools would you use to visualize #syntheny between two #eukaryote #genomes ?

Please share!
#genomics #dataviz

What RNA-Seq datasets are everyone using for RNA-Seq differential analysis workshops, using {DESeq2} or {limma} #RStats?

Two or three categories, and ideally a good (4 or 5+) number of replicates, human or mouse?

We have some new methods in ontology enrichment, and we really could use some more datasets to try them on.

I've found the {airways} dataset, and lung adenocarcinoma from {recount3} (as an easy pull). Looking for others. TIA.

Looking for some suggestions - I'm working with Archaeal genomic regions whose optimally fitting model seems to be Tamura-Nei (https://doi.org/10.1093/oxfordjournals.molbev.a040023).

Would it be too much to suspect the Archaeal region is under similar types of evolutionary pressure?

At my workplace, we're looking into how we can support the processing of very large datasets in R. It would be wonderful if some bioinformaticians could answer a couple of questions to direct us to the problem points.

We're hoping that we can publish something out of this that will be helpful to everyone in the field: https://forms.office.com/r/jNd2cbEZkh

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.

After months of work I'm so happy that our new preprint is online!

Profiling the expression of #transportome genes in #cancer: a systematic approach.
https://www.biorxiv.org/content/10.1101/2023.07.18.549498v1

It's a bit unfinished but it's by design! We want and need #feedback from #bioinformatics and #physiology people to move forward. I've tried to follow #openscience principles, so the pipeline is completely autonomous, containerized and the code for the paper is there, included in the repos!

Profiling the Expression of Transportome Genes in cancer: A systematic approach

The transportome, the -omic layer encompassing all Ion Channels and Transporters (ICTs), is crucial for cell physiology. It is therefore reasonable to hypothesize a role of the transportome in disease, and in particular in cancer.

I wanted to share with you a new thing I'm working on: https://biohandbook.me/

It's a resource for practical best practices and tips to use in bioinformatic analyses. The idea is to work together to define standards and workflows and write them down. I love the open science, FAIR data and FAIR code philosophy but there are not many easy-to-use and direct resources around to actually tell you how to do things in the bioinformatics world.
