scrnaseq – Integrating scRNA-seq data using raw data

I believe when you say alignment, you mean aligning reads to a genome (sometimes to transcriptome) and count these to get count matrices. In the aforementioned paper, however, what is meant is “bringing different data sets to a level where they can be compared/integrated/…”. Basically scRNA-seq data are heavily prone…

Novel diagnostic biomarkers for keloid based on GEO database

Introduction Keloid is excessive fibrosis of the skin that extends beyond the area of injury and does not regress.1 Keloid can occur in the joints and mouth after several years of severe injury, including burns, chemical injury, wound, and surgical incision.2 Keloids on the joints affect the quality of life,…

SCHNAPPs – Single Cell sHiNy APPlication(s)

Abstract : Single-cell RNA-sequencing (scRNAseq) experiments are becoming a standard tool for bench-scientists to explore the cellular diversity present in all tissues. Data produced by scRNAseq is technically complex and requires analytical workflows that are an active field of bioinformatics research, whereas a wealth of biological background knowledge is needed…

STARsolo –EmptyDrops_CR parameters

STARsolo –EmptyDrops_CR parameters 1 I’m having some issues with the alignment of 10x scRNAseq data to a custom genome and I thought it would be good to do a stricter filtering on the cells so more cells get filtered out as empty droplets. Apparently STARsolo has several filtering algorithms, of…

How to load Seurat Object into WGCNA Tutorial Format

I am really new to programming so it’s probably just my inexperience, but I am not sure how to load my Seurat object into a format that works with WGCNA’s tutorials (horvath.genetics.ucla.edu/html/CoexpressionNetwork/Rpackages/WGCNA/Tutorials/)….
