cmtk

Computational Morphometry Toolkit

A software toolkit for computational morphometry of biomedical images, CMTK comprises a set of command line tools and a back-end general-purpose library for processing and I/O. The command line tools primarily provide the following functionality: registration (affine and nonrigid; single and multi-channel; pairwise and groupwise), image correction (MR bias field estimation; interleaved image artifact correction), processing (filters; combination of segmentations via voting and STAPLE; shape-based averaging), statistics (t-tests; general linear regression).

atac

genome assembly-to-assembly comparison

atac computes a one-to-one pairwise alignment of large DNA sequences. It first finds the unique k-mers in each sequence, chains them to larger blocks, and fills in spaces between blocks. It was written primarily to transfer annotations between different assemblies of the human genome. The output is a set of ungapped 'matches', and a set of gapped 'runs' formed from the matches. Each match or run associates one sequence with the other sequence. The association is 'unique', in that there is no other (sizeable) associations for either sequence. Thus, large repeats and duplications are not present in the output - they appear as unmapped regions. Though the output is always pairwise, atac can cache intermediate results to speed a comparisons of multiple sequences. This package is part of the Kmer suite.
