\title{stand alone function to generate a scaffold containing only ncRNA location from ENSEMBL}
\description{
   The scaffold contains chr stand start and end position of ncRNA. ENSEMBL retrieved spicies are 
   miRNA,Mt_rRNA,Mt_tRNA,rRNA,snoRNA,snRNA
}
\usage{ncScaffold(genome, fasta)}
\arguments{
\item{genome}{The genome code for H sapiens is hg19, for M musculus is mm9 and for R norvegicus is rn4}
\item{fasta}{If fasta is TRUE a fasta file with the sequences retrieved by ncScaffold will be produced}

}
\details{
  The scaffold is used to map reads data into regions only associated to ncRNAs
