This GitHub repository provides an API and visualization of the cost of sequencing over time. Sequencing cost data comes from NHGRI DNA sequencing costs. It also contains data for the growth of sequence data in SRA, with data from SRA stats.
I like to use these plots showing the rapid decrease in sequencing costs in lectures and presentations, or the rapid growth of available sequences, but it was a challenge to keep the plots up-to-date. The plots and data provided directly from NHGRI was not amenable to be permanently linked in a lecture that would auto update, because URLs would change, new plots would be produced rather than updating old links with new data, etc. To make it more useful, I needed a stable URL for data and visualization. So, I made one and put it here so that anyone can update the data. I have simply reformatted the data to make it more FAIR; instead of an excel spreadsheet and an graphical image, I provide an API to access the data, and a vega-lite dynamic plot that just retrieves that data. This, hosted in a persistent spot, makes it possible to produce presentations that are always automatically up-to-date.
You can get the raw CSV data at:
- Costs: https://databio.org/seqcosts/data/sequencing_cost.csv.
- SRA content: https://databio.org/seqcosts/data/sra_stat.csv.
You can view corresponding vega-lite visualizations at:
- Costs: https://databio.org/seqcosts/cost.html.
- SRA data: https://databio.org/seqcosts/sra.html.
If you want to use the plot in a presentation or web page, you have two options
You can look at how I embedded it in the html pages above and just do something similar to use the underlying data however you want.
You can embed the HTML page using an <iframe> like this:
<iframe src="https://databio.org/seqcosts/sra.html" width="950" height="550"></iframe>
<a style="font-size:0.6em" href="https://databio.org/seqcosts">databio.org/seqcosts</a>
If you use this and notice it's not updated, please add any new rows to data/sequencing_costs.csv via Pull Request.
