Inparanoid是一个寻找物种间直系同源基因的软件,同时相应的网站目前包含了100 organisms, 1687023 sequences。
Inparanoid单机版程序是一款非常优秀的寻找直系同源基因(orthologs)的工具,目前已经开发到4.1版本,可以在线获取(http://software.sbc.su.se/cgi-bin/request.cgi?project=inparanoid)。
软件的基本用法:
1. 输入数据:
两个物种的全部蛋白序列,分别以fasta格式存储,A.pep, B.pep
2.准备工作:
该软件需要调用系统中其他程序,如BLAST,使用前需要修改程序开头部分的BLAST路径设置。
该软件的相关参数也在程序源文件中修改
3.运行方法:
perl inparanoid A.pep B.pep
4.程序输出:
# Output options: #
$output = 1; # table_stats-format output #
$table = 1; # Print tab-delimited table of orthologs to file "table.txt" #
# Each orthologous group with all inparalogs is on one line #
$mysql_table = 1; # Print out sql tables for the web server #
# Each inparalog is on separate line #
$html = 1; # HTML-format output #
