Concaterpillar
Concaterpillar is a hierarchical likelihood-ratio test for phylogenetic congruence. The most recent version of Concaterpillar, implementing MPI-based distribution of subprocesses, can be downloaded here. You can also get the users' manual.
Features added:
Concaterpillar versions 1.7.2 - 1.8a:
- These versions and subsequent versions will be hosted at Jessica Leigh's site here.
Concaterpillar 1.5:
- Removed -a and -r steps... these are now integrated in -t
- Support for RAxML 7.2
- Uses the subprocess Python module (availble in Python 2.5 on: for older Python installations, you'll need Concaterpillar 1.4)
- Fixed some MPI cleanup problems
Note to MPI users: We will be migrating to mpi4py shortly, rather than
pyMPI, as pyMPI has not been updated in several years
A Windows version of Concaterpillar v1.4 is available upon request from the author by emailing jessica{dot}w{dot}leigh{at}gmail{dot}com.
While windows is not officially supported a poorly tested version is available due to user requests.
Concaterpillar 1.4:
- support for nucleotide alignments
- pre-screening to make sure that all alignment pairs have enough taxa in common
- added a debug flag (-d, --debug) to print out all output from RAxML in case users are experiencing problems
- added a cleanup step to remove old RAxML output files that might cause subsequent runs to crash (user will be asked before files are deleted)
- added an optional flag to allow Concaterpillar to old RAxML output files without asking (-n, --noask)
- support for "relaxed" Phylip alignment format (not strictly 10 characters per sequence name)
Concaterpillar 1.3:
- fixed some bugs that might be encountered if some of your alignments have extremely different true phylogenies (thanks to Haruo Suzuki for finding this)
Concaterpillar 1.2:
- trees are inferred and evaluated using RAxML (faster and more accurate)
- an improved algorithm for resuming interrupted runs has been implemented
- an installation script has been added to locate programmes on which Concaterpillar depends
- support for more substitution models has been added
