Iain Macaulay organised a #singlecell meeting at Norwich’s Earlham Institute earlier this month. The meeting was fun and there were some great presentations during a day of talks and discussion on the development and application of single cell technologies. 100+ #singlecell analysis methods at www.tinyurl.com/mqabyur One that […]
The Genomics England project (a.k.a. UK100k genomes) is known as a whole genome sequencing project. It aims to sequence 100,000 genomes from UK NHS patients with Rare Disease or Cancer. But Genomics England have a very nice tool for people interested in targeted sequencing via […]
Index-swapping appears to be driven by excess adapter/primer (Illumina whitepaper). The take-home messages are 1) to use UDIs (unique dual-indexes), and 2) clean-up your libraries to remove left-over adapter/primer. Later in this post I’m going to work through one solution for getting rid of any remaining adapter/primer in an NGS library; but […]
This is a first for me as I’ve not finished this post at all! Instead I’m going to use this as a space to document my ideas, and experiences, in bringing Oxford Nanopore’s RNA-seq into my core lab at the CRUK Cambridge Institute. I’m hoping […]
Day 2 of London Calling. Keep an eye on Twitter. Watch for more coverage from @Gringer, ONT, NextGenSeek…let me know about other sources and I’ll add them here! ONTs London Calling 2017: Day 1 updates ONTs London Calling 2017: Day 2 updates Keiths OmicsOmics roundup. Gordon’s good morning wake-up […]
When will nanopore sequencing push short-reads (i.e. Illumina) off their pedestal? According to Clive PromethION is the Illumina killer…but this same conversation was going on many times at London Calling. I wanted to highlight two areas that might be about to flip to ONTs advantage […]
I’m excited to be at ONTs London Calling event today and tomorrow. Expect to see lots of coverage on Twitter. Missed the workshop yesterday or want a late preview of what’s coming then head over to Keith’s OmicsOmics blog. Update: coverage from @Gringer, ONT, NextGenSeek (storified […]
Last week I followed up on the index-swapping issue after Illumina released their white paper and also covered what Ethan Linck at The Molecular Ecologist had posted about the Sinha et al BioRxiv paper. In that post I said I’d write a follow-up post about index design over the weekend – here it is! […]
Illumina released a white paper this week describing their efforts to understand the index-swapping issues with the ExAmp chemistry. This story has been covered many times and got lots of Tweets in the days since the BioRxiv paper from Stanford was uploaded. Megan Molteni at Wired wrote a lengthy […]
A paper uploaded to BioRxiv yesterday is the first (almost) published report of index-swapping on Illumina’s Exclusion-Amplification (ExAmp) chemistry. The paper: Index Switching Causes “Spreading-Of-Signal” Among Multiplexed Samples In Illumina HiSeq 4000 DNA Sequencing, by a group from Stanford Functional Genomics Facility published a re-analysis of single-cell […]
