The biobambam package contains a tool called bammarkduplicates. It produces results which should be quite similar to those of Picard's MarkDuplicates tool while avoiding the sometimes high memory requirements of the Java implementation. The source code is available on github at https://github.com/gt1/biobambam, binaries for some versions of Linux are at ftp://ftp.sanger.ac.uk/pub/users/gt1/biobambam and also on launchpad https://launchpad.net/biobambam . It was developed at the Sanger Institute because the Java tool failed with out of memory type errors for a number of (at least locally high depth) BAM files, which required manual intervention (rerunning compute jobs with higher memory settings, which blocks otherwise free CPU cores because a single one is using all the RAM). If someone is interested in the algorithmic background, there is a preprint at http://arxiv.org/abs/1306.0836 .

The immune system’s power comes from its genetic diversity, allowing myriad threats to be neutralized through first recognizing foreign antigens. That diversity is also what makes the immune system so difficult to study. Recent advances in sequencing technology and computational biology, however, are giving researchers new tools to understand immune responses and immune-related diseases in greater detail.
