功能简介

分析模块，默认输入Fasta格式的细菌完成图和草图组装结果。采用RNAmmer程序进行rRNA预测。封装了Software：rnammer-1.2。

RNAmmer  predicts ribosomal RNA genes in full genome sequences by utilising two levels of Hidden Markov  Models:  An  initial  spotter  model searches  both  strands.  The  spotter model is constructed from highly conserved loci within a structural alignment of known  rRNA  sequences. Once  the  spotter  model  detects  an  approximate position of a gene, flanking regions are extracted and  parsed  to  the  full  model  which matches  the  entire  gene.   By  enabling  a  two-level approach it is avoided to run a full model through an entire genome sequence  allowing  faster predictions.
