Computational biology and genomics
As you may have learned in school, ribosomes are cell organelles that can be thought of as protein factories because they aid in the synthesis of proteins. The eukaryotic ribosome is made up of ribosomal proteins and ribosomal RNA (rRNA). This post is about ribosomal protein gene expression and not non-coding rRNAs. I was interested…
The Chromium Single Cell 3′ Solution is a commercial platform developed by 10x Genomics for preparing single cell cDNA libraries for performing single cell RNA-seq. In addition, 10x Genomics have developed an entire software suite called Cell Ranger that can process the raw BCL files produced by an Illumina sequencer and output a final gene-barcode…
I was going to write a post on using the Seurat alignment method as a batch correction tool but as it turned out the two datasets that I chose didn’t seem to have strong batch effects! I heard about the alignment method sometime last year but was motivated to try it out after listening to…
Monocle is an R package developed for analysing single cell gene expression data. Specifically, the package provides functionality for clustering and classifying single cells, conducting differential expression analyses, and constructing and investigating inferred developmental trajectories. The toolkit provides various alternative approaches for each analysis, hence your workflow may differ from the approach I’ve taken in…
This post is outdated; please refer to the official Seurat vignettes for more information. This post follows the Peripheral Blood Mononuclear Cells (PBMCs) tutorial for 2,700 single cells. It was written while I was going through the tutorial and contains my notes. The dataset for this tutorial can be downloaded from the 10X Genomics dataset…
