drosophila: Tissue type and transcription factor binding data during...

In Evatar/baycn: Bayesian Inference for Causal Networks

Description

Zinzen et al. (2009) measured in vivo transcription factor binding for five key transcription factors using ChIP-chip assays at two hour intervals during drosophila mesoderm development. The five transcription factors are: Twist (Twi), Tinman (Tin), Myocyte enhancing factor 2 (Mef2), Bagpipe (Bap), and Biniou (Bin). Both Twi and Tin were assayed from 2-8 hours, Mef2 from 2-12 hours, Bap from 6-8 hours, and Bin from 6-12 hours. In addition, Zinzen et al. identified six tissue types based on tissue specific expression: mesoderm (Meso), somatic muscle (SM), visceral muscle (VM), cardiac muscle (CM), mesoderm and somatic muscle (Meso&SM), and somatic and visceral muscle (SM&VM). All data are binary and measured at 310 cis-regulatory modules.

Usage

data(drosophila)

Format

An object of class "list" containing tissue type and transcription factor binding data during drosophila mesoderm development. The first element in the list is a matrix which contains the data in the original form. The second element in the list is a matrix that contains the binary data. For this matrix any value greater than zero to changed to a one. For both data sets the tissue type data appears in the first six columns of the data matrix and the remaining 15 columns contain the transcription factor binding data.
