+Trinity_ assembles transcript sequences from Illumina RNA-Seq data.
+This tool computes the N50 statistic limited to the top most highly expressed transcripts that represent x% of the total normalized expression data. This requires that you have first performed transcript abundance estimation with 'Align reads and estimate abundance for a de novo assembly of RNA-Seq data by Trinity' tool and that you have built the expression matrix with 'Build expression matrix for a de novo assembly of RNA-Seq data by Trinity' tool. 
+
+**Inputs**
+
+It takes as input a transcriptome assembled with Trinity and the matrix of normalized expression values produced by 'Build expression matrix for a de novo assembly of RNA-Seq data by Trinity' tool.
