Homer这个软件比较强大,主要做ChIP-Seq分析,除此之外,还可以做RNAseq以及microarray的分析
原文:http://homer.ucsd.edu/homer/motif/rnaMotifs.html
Analyzing Co-regulated Gene Lists for RNA motifs
用法:findMotifs.pl downregulated.genes.txt human-mRNA MotifOutput/ -rna -len 8
输入文件:3 mandatory arguments: A gene ID input file, the name of the promoter set (which is tied to an organism), and an output directory for all of the output files.
解释:输入文件downregulated.genes.txt为下调的gene list ,human-mRNA为promoter set,MotifOutput为输出文件夹
例子:

for sample in `ls *txt |cut -d '.' -f1`;do findMotifs.pl ${sample}.txt human ${sample}/ -start -400 -end 100 -len 8,10 -p 16 ;done


结果:

相应的promoter或者genome安装:
查看可以安装的文件:perl /path-to-homer/configureHomer.pl -list
安装或者卸载: "-install <package name>" or "-remove <package name>".
如:
perl /path-to-homer/configureHomer.pl -install human
安装promoter则需要加“-p”,除此之外还有-o:organism -g genome
perl /path-to-homer/configureHomer.pl -install human-p
