Introduction – Refgenie (

An interesting tool to help with downloading references and also pre-built indices.

Refgenie manages storage, access, and transfer of reference genome resources. It provides command-line and Python interfaces to download pre-built reference genome “assets”, like indexes used by bioinformatics tools. It can also build assets for custom genome assemblies. Refgenie provides programmatic access to a standard genome folder structure, so software can swap from one genome to another.

It all started out as a good idea. Have scientists congregate and decide how well software tools work. Alas, it seems it has gone downhill. A 13 tweet thread from Steven Salzberg explains.

A benchmark of batch-effect correction methods for single-cell RNA sequencing data | Genome Biology | Full Text (

We compare 14 methods in terms of computational runtime, the ability to handle large datasets, and batch-effect correction efficacy while preserving cell type purity. Five scenarios are designed for the study: identical cell types with different technologies, non-identical cell types, multiple batches, big data, and simulated data. Performance is evaluated using four benchmarking metrics including kBET, LISI, ASW, and ARI. We also investigate the use of batch-corrected data to study differential gene expression.

Autocorrect errors in Excel still creating genomics headache (

Despite geneticists being warned about spreadsheet problems, 30% of published papers contain mangled gene names in supplementary data.
