\title{
\code{SDFset} to \code{character}
Convert \code{SDFset} to SMILES (\code{character})
}
\description{
Accepts one compound in an \code{SDFset} container and returns the corresponding
SMILES string (Simplified Molecular Input Line Entry Specification). 
The compound is submitted to the ChemMine Tools web service for conversion
with the Open Babel Open Source Chemistry Toolbox. If the input object
contains multiple items, only the first is converted.
}
\usage{
sdf2smiles(sdf)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{sdf}{
  	  A \code{SDFset} object which contains one compound
}
}
\value{
\item{character}{ for details see ?"character"}
