\usage{
getTxDb(file = NA, organism, release = NA, tx_attrib = "gencode_basic", ...)
}
\arguments{
\item{file}{File argument for \code{\link{makeTxDbFromGFF}}
(see help page for \code{\link{makeTxDbFromGFF}}).
If \code{NA} (default), function will return a \linkS4class{TxDb}
object from Ensembl using \code{\link{makeTxDbFromEnsembl}}.}

\item{organism}{String specifying genus and species name
(e.g. "Homo sapiens" for human). Required if \code{file} is not
provided. If \code{file} is provided, this value can be set to \code{NA}
to have organism information as unspecified.}

\item{release}{Ensembl release version; passed to
\code{\link{makeTxDbFromEnsembl}} when \code{file} is not specified.
See help page for \code{\link{makeTxDbFromEnsembl}}.}

\item{tx_attrib}{Argument passed to \code{\link{makeTxDbFromEnsembl}}
when \code{file} is not specified. See help page
for \code{\link{makeTxDbFromEnsembl}}.}

\item{...}{Additional arguments passed to either
\code{\link{makeTxDbFromGFF}} (if \code{file} is specified) or
\code{\link{makeTxDbFromEnsembl}} if \code{file} is NA.}

\value{
A \linkS4class{TxDb} object.
}
\description{
Convenience function for constructing
    a \linkS4class{TxDb} object.

    # To obtain a TxDb from a GFF file:
