Batch-effect detection, correction and characterisation in Illumina HumanMethylation450 and MethylationEPIC BeadChip array data | Clinical Epigenetics

Experimental design and processing steps For the EpiSCOPE study [20], DHA supplementation and gender were balanced as much as possible across the 12 450K BeadChips on each glass slide, with these factors also randomly distributed over the 6 rows and 2 columns of 31 slides (Additional file 1: Fig. S1). Blood…

Petabase-scale sequence alignment catalyses viral discovery

Serratus alignment architecture Serratus (v0.3.0) (github.com/ababaian/serratus) is an open-source cloud-infrastructure designed for ultra-high-throughput sequence alignment against a query sequence or pangenome (Extended Data Fig. 1). Serratus compute costs are dependent on search parameters (expanded discussion available: github.com/ababaian/serratus/wiki/pangenome_design). The nucleotide vertebrate viral pangenome search (bowtie2, database size: 79.8 MB) reached processing rates…

Transcription Factor Functions

Transcription Factor Functions 1 I have been wondering if there is a database that contains information about whether a transcription factor has a repressive or an activating or a context-dependent function. factor database transcription • 71 views If you performed a whole-genome FIMO scan, selecting those hits that match your…

Frontiers | DNA Methylation and RNA-Sequencing Analysis Show Epigenetic Function During Grain Filling in Foxtail Millet (Setaria italica L.)

Introduction Gene expression is not only controlled by DNA sequences but also by epigenetic marks in eukaryotes. DNA methylation as one of the important epigenetic modifications has been demonstrated as closely related to gene expression in biological processes, such as transcriptional activity, developmental regulation, and environmental responses (Maunakea et al.,…

SRA splitting for each metagenome-assembled genome

Job:SRA splitting for each metagenome-assembled genome 0 Hi everybody, we obtained viruses from water and sequenced them with Illumina. we formed different metagenomic-assembled genomes and get a Bioproject number and Biosample numbers (for each of them). Now, i should do SRA submission. But i cannot submit for my all genomes…

Python fast way to get ONLY MAIN metadata for GSE ? (not walking through thousands underlying GSM-samples : slow or even endless)

  Not Python but using EntrezDirect you can get: $ esearch -db bioproject -query “GSE118723” | esummary | xtract -pattern DocumentSummary -element Project_Description Quantification of gene expression levels at the single cell level has revealed that gene expression can vary substantially even across a population of homogeneous cells. However, it…
