A free web service that allows to study short read data from small RNA-seq experiments. DARIO provides a wide range of analysis features, including quality control, read normalization, ncRNA quantification and prediction of putative ncRNA candidates. The expression data and ncRNA predictions can be downloaded in the standardized BED format. We provide a script to locally convert SAM files and other mapping files to the BED format. The script is optimized to greatly reduce the amount of data that has to be uploaded to the DARIO server.
