序列拼接软件velvet 1.1.01发布

2011-3-29日发布了velvet最新版本1.1.01，在这一版本中终于支持多线程运行了！！
速度可以提高4-10倍，还有一些另外的修改，附上作者的原话：

Dear Velvet users,

it is my pleasure to announce the release of Velvet 1.1.01!

Sylvain Forêt from ANU did a excellent job multithreading Velvet, 
meaning that it can use multiple CPUs on the same computer, thus freeing 
up the computer that much faster. 4 to 10 fold accelerations have been 
reported. He also reduced the memory footprint, and improved the use of 
mate-pairs, filtering out paired-end contamination.

Also in this new version Yasubumi Sakakibara and colleagues shared their 
MetaVelvet code, which is designed to analyze metagenomic data.

Regards,

Daniel

  3. velvet 1.1.04发布，作者声明：
    ”Velvet 1.1.04 is now available on github or
    http://www.ebi.ac.uk/~zerbino/velvet/velvet_latest.tgz. In it:

    – Matthias Haimel found a potentially serious bug which would affect
    paired-read assemblies since v. 1.1.01 (released March 30) – you might
    want to double check your latest assemblies.

    – Sylvain For?t found a bug in the output of gaps within long node sequences
    – A typo was corrected in the Manual
    – As pointed out by several users, the correct coverage of nodes is now
    output in the contigs.fa file
    – Compilation warnings for k < 32 were corrected
    – Adrian Platts suggested that velveth no longer squashes the Log file,
    – Adrian Platts suggested that TourBus display how many nodes are to be
    visited

    Best regards,

    Daniel

  7. 请问一下：有没有什么工具可以结合已知的基因组序列作为参考来对转录组数据进行拼接啊？？

    • @wufawfua velvet有columbus扩展可以进行有reference的拼接，另外有Oases扩展可以进行转录组的拼接，你可以试试把这两者结合起来使用~
