Average region length	86.73
Description	This dataset contains samples of miRNA-Seq: miRNA quantification (i.e., the calculated expression for all reads aligning to a particular miRNA).<br>
	It is directly derived from data available on the old TCGA portal and transformed into GDM format through the TCGA2BED pipeline.<br>
	Documentation is available at http://bioinf.iasi.cnr.it/tcga2bed/data/TCGA2BED_format_definition.pdf.<br>
	<br>
	miRNA-Seq data are derived from the sequencing of micro RNAs (miRNA); they contain information about both nucleotide sequence and expression.<br>
	<br>
	The dataset includes tab separated BED files, in which the miRNA-seq Mirna quantification file is converted, with the following fields:<br>
	<ol>
	<li>chrom (retrieved from miRBase database9, according to the miRNA id provided in field 5, e.g., "chr9")</li>
	<li>chromStart (retrieved from miRBase database9, according to the miRNA id provided in field 5, e.g., 94175957)</li>
	<li>chromEnd (retrieved from miRBase database9, according to the miRNA id provided in field 5, e.g., 94176036)</li>
	<li>strand (retrieved from miRBase database9, according to the miRNA id provided in field 5, e.g., '+')</li>
	<li>mirna_id (retrieved from the 1. field of the TCGA miRNA-Seq file, e.g., "hsa-let-7a-1")</li>
	<li>read_count (retrieved from the 2. field of the TCGA miRNA -Seq file, e.g., 29726)</li>
	<li>reads_per_million_miRNA_mapped (retrieved from the 3. field of the TCGA miRNA -Seq file, e.g., 12429.699816)</li>
	<li>cross-mapped (retrieved from the 4. field of the TCGA miRNA -Seq file, e.g., 'N')</li>
	<li>entrez_gene_id (retrieved from HUGO Gene Nomenclature Committee (HGNC)10 starting from the mirna_id provided in field 5)</li>
	<li>gene_symbol (retrieved from HUGO Gene Nomenclature Committee (HGNC)10 starting from the mirna_id provided in field 6)</li>
