t2prhd

t2prhd is a Perl script which generates simple diagrams that highlight relationships of sequence repeats detected by using a profile HMM in two sequences. Homology relations are identified on the basis of the phylogeny of repeats.

The approach is described in: Sipos, B., Somogyi, K., Pénzes, Zs., Andó, I. (2008) t2prhd: a tool to study the patterns of repeat evolution. - BMC Bioinformatics 9: 27 [doi:10.1186/1471-2105-9-27].

Manual page: Text PDF The manual page is embedded in the script in POD format, readily available by issuing "perldoc t2prhd". Due to resource limitations, the script is no longer accessible as an online tool.
