Maximum likelihood phylogeny based on the core genome alignment of 616 Streptococcus pneumoniae isolates

Newick format maximum likelihood phylogeny generated using the 106,196 polymorphic sites in a core genome alignment of 616 Streptococcus pneumoniae isolates. The tree was produced by RAxML using the general time reversible substitution model with a four category gamma distribution to correct for rate heterogeneity.本数据集为基于616株肺炎链球菌（Streptococcus pneumoniae）分离株的核心基因组比对中106196个多态性位点构建的最大似然系统发育树，以Newick格式(Newick format)存储。该系统发育树由RAxML软件基于一般时间可逆替换模型构建，并采用四类别伽马分布校正进化速率异质性。
