Hello

I saw this great post about how someone has plotted the growth rate of the trace archive. Given all the articles talking about the bioinformatics data deluge/tsunami/bonanza I was suprised to see the growth curve decreasing. Just in case I was going mad I searched the page for the word 'log' to make sure it wasn't a log plot showing exponential growth. Is there any particular reason why growth rate is decreasing in this archive? I just though this was interesting and wondered if anyone had any comments

thanks a lot

I find that comment snide. Is that in-keeping with the general ethos of the scientific community? I'm not from a biology background and I did not realise the point Daniel kindly elucidated below. I'm not sure why you needed to go out of your way to type a comment to belittle me.

yeah and why aren't more new MIDI ringtones coming out these days?

my apologies. here's the deal though - no archive can really hope to hold 1TBp runs which are coming from present-day NGS sequencers. They will either hold an alignment, or SNP calls, or an assembly, but they cannot store or serve that much raw data.

Perhaps because we don't do as much capillary sequencing anymore? Jeremy was alluding to that there I imagine. The Trace archive only holds data from gel/capillary platforms. Whilst they are still in use they do not constitute (I would imagine) the bulk of modern sequencing output.

I think its policy these days to throw away 'raw' data from Illumina, 454 and SOLiD machines, it takes up too much space. Just bases and qualities please, in a fairly standard text format. That takes up quite enough space as it is..

The SRA/ENA are the repositories for NGS data - so maybe you should look at them to see what the rate of growth is for current sequencing technologies.
