\title{ Calculate Tm }
\description{
  Calculate melting temperature (Tm) using the nearest-neighbor base-stacking algorithm and the unified thermodynamic parameters.
}
\usage{
calcTm(x, ...)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{x}{ characters containing nucleotide sequences (ex: \option{"ATCGGAA"}) or an object of class \code{ExpressionSet} }
  \item{\dots}{ Additional arguments passed to methods:
	\code{\item{strand1.concentration}}{ numeric value specifying concentration of strand 1 (default is 2e-07)}
	\code{\item{strand2.concentration}}{ numeric value specifying concentration of strand 2 (default is 2e-07)}
	\code{\item{method}}{ character value specifying the Tm algorithm to use (default is \option{"nearest-neighbor"}); currently not supported }
  }
}
\value{
  Returns a numerical value indicating the predicted melting temperature (Tm) of the sequence in degrees Celsius. A value of \option{NA} is returned if the function encounters an error that prevents proper Tm calculation.
