v0.4.0 contains greatly expanded functionality for distilling what models have learned about cis-regulation after they have been trained. This release includes a new seqlet caller that is optimized for speed and simplicity, functionality for mapping seqlets (from the new caller or from the tfmodisco caller) to a database of motifs using TOMTOM, and for calculating statistics about these annotations, and more. Please see the additional tutorials and vignette for concrete examples.
