"""
The TADBit algorithm works on raw chromosome interaction count data.
The normalization is neither necessary nor recommended,
since the data is assumed to be discrete counts.
TADBit is a breakpoint detection algorithm that returns the optimal
segmentation of the chromosome under BIC-penalized likelihood. The
model assumes that counts have a Poisson distribution and that the
expected value of the counts decreases like a power-law with the
linear distance on the chromosome. This expected value of the counts
at position (i,j) is corrected by the counts at diagonal positions
(i,i) and (j,j). This normalizes for different restriction enzynme
site densities and 'mappability' of the reads in case a bin contains
repeated regions.
:param x: a square matrix of interaction counts in the HI-C data or a list
of such matrices for replicated experiments. The counts must be evenly
sampled and not normalized. x might be either a list of list, a path to
a file or a file handler
:param 1 n_cpus: The number of CPUs to allocate to TADBit. If
n_cpus='max' the total number of CPUs will be used
:param auto max_tad_size: an integer defining maximum size of TAD. Default
(auto) defines it as the number of rows/columns
:param False no_heuristic: whether to use or not some heuristics
:param False get_weights: either to return the weights corresponding to the
Hi-C count (weights are a normalization dependent of the count of each
columns)
:returns: the :py:func:`list` of topologically associated domains'
boundaries, and the corresponding list associated log likelihoods.
Depending on the value of the get_weights parameter, may also return
weights.
