Today I learned how to store gene expression data in (multiple) parquet files, and query them as a single dataset from R with the {arrow}, {duckdb} or {sparklyr} packages. I am amazed by {duckdb}'s speed ๐ - even on my laptop! Here's a blog post with what I learned: https://tomsing1.github.io/blog/posts/parquet/ #TIL #RStats #duckdb #parquet #spark #compbio #rnaseq

MicroRNA Gene Reports now display high-throughput RNA-Seq expression data from FlyAtlas2 (Leader et al 2018 http://flybase.org/reports/FBrf0237746) & meta-analysis of Lai lab experiments (http://flybase.org/reports/FBrf0230987).
These datasets are presented in the High-Throughput Expression Data sub-section of the gene reportโs Expression Data section; data for any given microRNA gene can be downloaded.

What is an industry-academia gap? It's when every 5th presentation in a conference is about a new method for #RNAseq to stratify #cancer patients, but only 0.0X% (!) of patients ever get RNAseq test (and even those are to support a proposal to develop yet another RNAseq method)

For #RNA sequencing results data analysis, a rich alternative to Cluster3 (http://bonsai.hgc.jp/~mdehoon/software/cluster/software.htm) and the no longer maintained Java TreeView (https://sourceforge.net/projects/jtreeview/) is #Phantasus.
An evolution of Morpheus (https://software.broadinstitute.org/morpheus/), Phantasus can be used online (https://artyomovlab.wustl.edu/phantasus/) or as an R package via Bioconductor (https://bioconductor.org/packages/release/bioc/vignettes/phantasus/inst/doc/phantasus-tutorial.html)

And this simulation #rstats code, shows why one must use use very short seeds when using #blast to map #nanopore #transcriptomic #RNAseq data (Q10 quality scores are not unheard of, in such datasets).
Take home message, one has got to work for their database searches for long read platforms

A substantial base calling quality improvement observed beta testing the #nanopore RNA004 direct #rnaseq protocol.
This is empirical data from commercial, multi-tissue RNA after poly(A) selection, aligned to hg38 with miminap2 -a -x splice --secondary=no.
Alignments (especially at splice junctions) look exceptional; I could see potential RNA modifications directly from basecalling output as mutations in IGV
Can confirm the Snapchat AI chat can provide basic #RNASeq analysis code ๐คฃ
