Y-DNA SNP testing chart

bar coding
I've removed the reference to bar coding. I've been told that the Wikipedia article that was linked here actually refers to a different type of bar coding. There is now a new Wiki page for next generation sequencing which includes a link to an Illumina leaflet providing further information on the bar coding process. From what I understand bar coding is an integral part of the NGS method. As both FTDNA and Full Genomes are using the Illumina HiSeq platform it seems that they would both be using this bar coding technology. DebbieKennett (talk) 09:00, 14 November 2013 (MST)

- Thanks Chris. It's an interesting analysis. I'm not quite sure what to do with this as the information was only posted in a Facebook group. Do you have any thoughts? DebbieKennett (talk) 14:56, 12 October 2014 (MDT)
Re-organising the charts
This page was originally set up to compare individual tests from different companies. The range of SNP tests on offer is now so complicated that the format no longer works. If we include YSEQ tests on here we would also need to add columns for FTDNA SNP packs and the new FGC test.
I’m wondering if the solution might be to convert the existing chart into a comparison of the different companies that offer SNP testing. We could have separate rows for each type of test (single SNP, SNP packs/panels, microarrays, Y-chromosome sequencing, whole genome sequencing). We could then have two additional charts for side by side comparisons of microarray and next generation sequencing tests.
