Wig
---

    Input wiggle data can be in variableStep (for data with irregular
    intervals) or fixedStep (for data with regular intervals). Regardless of
    the input, the output will always in bedGraph format. bedGraph format is
    similar to wiggle format and can be converted into BigWig format using UCSC
    wigToBigWig tool. We export files in bedGraph because it is usually much
    smaller than file in wiggle format, and more importantly, CrossMap
    internally transforms wiggle into bedGraph to increase running speed.

Please see `the manual <http://crossmap.sourceforge.net/#convert-wiggle-bigwig-format-files>`__ for more details
