gdata.utils.bw_to_w5z#

gdata.utils.bw_to_w5z(input, output, *, zfp=None, compression_level=19, tolerance=0.0, norm_factor=None)#

Convert a BigWig file to a compressed HDF5 file with optional ZFP compression and normalization.

Parameters:

  • input (str) – Path to the input BigWig file or a URL.

  • output (PathBuf) – Path to the output HDF5 file.

  • zfp (Optional[bool]) – Whether to use ZFP compression. If None, it will be determined automatically.

  • compression_level (int) – Compression level for ZFP (1-21). Higher values yield better compression but are slower.

  • tolerance (float) – Tolerance for ZFP compression. Higher values yield better compression but lower precision.

  • norm_factor (Optional[float]) – If provided, the data will be normalized such that the total sum equals this factor.

Return type:

None
