Usage

gintervals.load_chain(file = NULL)

Details

This function reads a file in 'chain' format and returns assembly conversion table that can be used in 'gtrack.liftover' and 'gintervals.liftover'.

Note: chain file might map a few different source intervals into a single target one. These ambiguous mappings are not presented in the data frame returned by 'gintervals.load_chain'.
