\title{Plot expression changes of top features along a TSCAN pseudotime path}
\usage{
plotTSCANPseudotimeGenes(
  inSCE,
  pathIndex,
  direction = c("increasing", "decreasing"),
  topN = 10,
  useAssay = NULL,
  featureDisplay = metadata(inSCE)$featureDisplay
)
}
\arguments{
\item{inSCE}{Input \linkS4class{SingleCellExperiment} object.}

\item{pathIndex}{Path index for which the pseudotime values should be used.
Should have being used in \code{\link{runTSCANDEG}}.}

\item{direction}{Should we show features with expression increasing or
decreeasing along the increase in TSCAN pseudotime? Choices are
\code{"increasing"} or \code{"decreasing"}.}

\item{topN}{An integer. Only to plot this number of top genes that are
increasing/decreasing in expression with increasing pseudotime along
the path in the MST. Default 10}

\item{useAssay}{A single character to specify a feature expression matrix in
\code{assays} slot. The expression of top features from here will be
visualized. Default \code{NULL} use the one used for
\code{\link{runTSCANDEG}}.}

\item{featureDisplay}{Specify the feature ID type to display. Users can set
default value with \code{\link{setSCTKDisplayRow}}. \code{NULL} or
\code{"rownames"} specifies the rownames of \code{inSCE}. Other character
values indicates \code{rowData} variable.}
}
\value{
A \code{.ggplot} object with the facets of the top genes. Expression
on y-axis, pseudotime on x-axis.
}
\description{
A wrapper function which visualizes outputs from the
\code{\link{runTSCANDEG}} function. Plots the genes that increase or decrease
in expression with increasing pseudotime along the path in the MST.
\code{\link{runTSCANDEG}} has to be run in advance with using the same
\code{pathIndex} of interest.
}
\examples{
data("mouseBrainSubsetSCE", package = "singleCellTK")
mouseBrainSubsetSCE <- runTSCAN(inSCE = mouseBrainSubsetSCE,
                                useReducedDim = "PCA_logcounts")
terminalNodes <- listTSCANTerminalNodes(mouseBrainSubsetSCE)
mouseBrainSubsetSCE <- runTSCANDEG(inSCE = mouseBrainSubsetSCE,
                                   pathIndex = terminalNodes[1])
plotTSCANPseudotimeGenes(mouseBrainSubsetSCE,
                         pathIndex = terminalNodes[1],
                         useAssay = "logcounts")
