Tdf

TDF is a binary file format that contains preprocessed summary information for display in a genome browser.

This format is an alternative to wig and the bigwig formats and is typically used for data that has a value per chromosomal position, like for example coverage data.

You can create TDF files directly from BAM files or from wig files.
