I've just finished an intensive course on NGS data analysis where command line based soutions where of course the best reported way to manage and make sense of data.
Playing with scripts, unix code and R language make you feel a sort of bioinformatic power. You start to blame all those wet-lab collegues spending hours on excel spreadsheets. You are amazed by the results of your last programming trick and effectivness of your command-line skills. Even if this make you proude, keep in mind that a screen full of symbols and over-a-million-row tables have to most og biologist and geneticists the same appeal of the flowing characters of The Matrix...As in the famous movie, not everyone can see the meaning behind the code, most of them will just see a bunch of chars and number, doubting that this is The real world!
A good visualization of genomic data from NGS experiments would make your results nicer to see, easier to explain and explore. Moreover, a colorful alignments of reads in genome browser style or a circos graph sure make a better impact when you show them in your presentations! The scientific community constantly ask for visulization tools that simplify the task of explaining and exploring NGS data, so that they became accessible to everyone, even to the old-school ones.
The last special issue of Briefings in Bioinformatics make an extensive review of the main visualization tools, with an overview on their peculiar advantages and main features. Web-based browsers, UCSC Genome Browser, IGV, Tablet, Bamview and GBrowse are all covered, making this issue the ideal answer to the collegue asking you: "I've just received this great NGS data, but what are all these bam and vcf files? I want to see them nicely placed on my favourite chromosome!".
