announcement: ABySS 2.0.0 release

[Ben Vandervalk]

Hi everyone,

I am pleased announce the release of ABySS 2.0.0
Release page: http://www.bcgsc.ca/platform/bioinfo/software/abyss/releases/2.0.0
Source tarball: https://github.com/bcgsc/abyss/releases/download/2.0.0/abyss-2.0.0.tar.gz

Description:

This release introduces a new Bloom filter assembly mode that enables large genome assemblies with minimal memory (e.g. 34 GB for H. sapiens with 76X coverage bfc-corrected reads). Bloom filter assemblies are currently less contiguous than the default (MPI) assembly mode but are still of high quality (e.g. 3.5 Mbp vs. 4.8 Mbp scaffold NG50 for H. sapiens). Bloom filter assembly mode is enabled by adding three 'abyss-pe' parameters (B = Bloom filter size, H = number of Bloom filter hash functions, kc = k-mer coverage threshold). See 'README.md' for an example.

This release also updates several 'abyss-pe' parameter defaults to be more suitable for large genome assemblies with recent Illumina data. In addition, ABySS 2.0.0 includes minor usability improvements for 'abyss-sealer' and removes an unnecessary build dependency on sqlite3.
