\name{LinearNet} \alias{LinearNet} \title{Dynamic Bayesian Network Inference Using Linear Interactions} \description{ Run Bayesian inference of linear interaction network. The function generates MCMC chains that can later be analysed. } \usage{ LinearNet( resultsFolder, timeSeries, ParamVec = NULL, chains = 2, user.seeds = NULL, Regulators = NULL, fixMe = NULL) } \arguments{ \item{resultsFolder}{Name of output folder. The folder will be created and the output of the run will be placed there.} \item{timeSeries}{Data matrix containing gene expression time series. Where genes will be placed in rows and time points in columns. Gene names may be included as row names.} \item{ParamVec}{A parameter vector created using "mcmc.defaultParams_Linear". If none is given, default parameters will be used. The vector contains parameters associated to the priors as well as MCMC run length. (See mcmc.defaultParams_Linear)} \item{chains}{Number of MCMC chains to run.} \item{user.seeds}{An optional vector with seeds to use for MCMC chains.} \item{Regulators}{An optional vector with the indices of which genes are regulators. If provided, all non-regulator genes will not be allowed to regulate.} \item{fixMe}{An optional matrix of size genes x genes, where columns represent regulators and rows regulated genes. The matrix informs the model of network connections known to be present/absent. For each position use either 0 (no regulation, fix off), 1 (known regulatory interaction, fix on) or NaN (no information, do not fix).} } \value{ For each chain run, a folder (chain1, chain2, ...) will be created and the output of the MCMC run will be placed there. The files will be B_mcmc (the coeffcients of the linear regression), Gamma_mcmc (the indicator variables of Gibbs variable selection), Lambda_mcmc (the precision of each regression), Mu_mcmc (the intercept of each regression) and Rho_mcmc (the network connectivity parameter). } \references{ Morrissey, E.R., Juarez, M.A., Denby, K.J. and Burroughs, N.J. 2010.
