For the assemblies I've been using this on however, my paired end reads are all Sanger reads where the distribution of fragment lengths is expected to vary widely, and I was happy to just look at the read placement in the assembly. Hmm. I wonder if Tablet could show the inferred fragment size (insert size) when the two reads are on the same fragment and the SAM/BAM field is not populated (i.e. left as zero).
Hi, Peter.We use Hawkeye to look for misassemblies, where mate-pairs are in AMOS nomenclature 'unhappy' (i.e. stretched or compressed in comparison to the expected insert length). It would be very useful to have a similar function in Tablet, and I've already mentioned comparison with Hawkeye to Iain Milne. I think Tablet is getting more useful as it develops, but Hawkeye is popular for a good reason: Detection of misassemblies.
The problem with Hawkeye is that it is difficult to install and run. That, in my opinion, is a major advantage of Tablet over Hawkeye but without mis-assembly metrics, Tablet is not as useful for my work. Despite this, I'm now starting to use Tablet because it's good :-)
