R scripts were modified slightly to remove genes which were not actually up and down regulated in the up and down regulation results files. The tables were simply sorted or reverse sorted based on fold change, but, for instance, with down-regulated genes there was previously no cutoff point removing positive fold change values. Also, a new script has been added (Number_of_Reads_BLASTed.py) which outputs the number of reads which are missing from BLAST results which are present in the adapter/primer removed library, indicating how many reads failed to BLAST to the miRNA reference genome.
