smallWig

SmallWig is a software tool that offers a new lossless compression method for WIG data that features random access functionalities, making it suitable for visualization, summary statistics analysis, and fast queries from the compressed files. It offers order of magnitude improvements in compression rates compared to bigWig and cWig and uses statistical data analysis and a combination of source coding methods to ensure high flexibility for different applications. SmallWig offers up to 18-fold compression rate improvements, up to 2.5-fold compression time improvements, and 1.5-fold decompression time improvements when compared with bigWig.
