Introducing robustness to maximum-likelihood refinement of electron-microsopy data
收藏 引用
ACTA CRYSTALLOGRAPHICA SECTION D-BIOLOGICAL CRYSTALLOGRAPHY 2009年 第7期65卷 672-678页
作者: Scheres, Sjors H. W. Carazo, Jose-Maria Ctr Nacl Biotecnol CSIC Madrid 28049 Spain
An expectation-maximization algorithm for maximum-likelihood refinement of electron-microscopy images is presented that is based on fitting mixtures of multivariate t-distributions. The novel algorithm has intrinsic c... 详细信息

MOLECULAR BIOLOGY AND EVOLUTION 2009年 第2期26卷 473-480页
作者: Cartwright, Reed A. N Carolina State Univ Dept Genet Bioinformat Res Ctr Raleigh NC 27695 USA
Insertions and deletions (indels) are fundamental but understudied components of molecular evolution. Here we present an expectation-maximization algorithm built on a pair hidden Markov model that is able to properly ... 详细信息
