1. 概述

• 这个数据包中含有6个列表，分别是：ENCODE，ITFP，Marbach2016，Neph2012，TRED，TRRUST，他们包含了不同数据来源的转录因子和靶向基因对应关系。
  • ENCODE的数据来自(http://hgdownload.cse.ucsc.edu/goldenpath/hg19/encodeDCC/wgEncodeRegTfbsClustered/)
  • ITFP的数据来自(http://itfp.biosino.org/itfp)，但该链接已失效，这里放一个这个数据库发表的文章链接(https://academic.oup.com/bioinformatics/article/24/20/2416/259750)
  • Marbach2016的数据来自(http://www.regulatorycircuits.org/)
  • Neph2012的数据来自(http://www.regulatorynetworks.org/)
  • TRED的数据来自(https://cb.utdallas.edu/cgi-bin/TRED/)，可能是网速问题，这个链接我也打不开
  • TRRUST的数据来自(http://www.grnpedia.org/trrust/)
