The BiomolecularStructures package provides several Bioinformatics-related modules for Julia.



Build Status Coverage Status Documentation Status


The BiomolecularStructures package provides several Bioinformatics-related modules:

  • WebBLAST - A module to communicate with the NCBI/EBI BLAST servers.
  • Kabsch - Superimposing protein structures
  • PDB - Utility functions for parsing PDB files
  • Plot - Rudimentary plotting of matrices of atomic coordinates
  • Mafft - Julia API for multisequence alignment with MAFFT
  • Modeller - Functions and scripts to use MODELLER with Julia

Documentation is available here: BiomolecularStructures

Binary Dependencies

The build script should take care of the BioPython dependency. Install MAFFT with sudo apt-get install mafft (or equivalent for other package managers) Modeller needs to be installed manually.

As the available MAFFT version may be different from the one we have tested with and we can't guarantee reproducibly working tests, the tests are disabled by default. You can reenable them by uncommenting the corresponding line in test/runtest.jl:

include(Pkg.dir("BiomolecularStructures", "test", "mafft.jl"))

Troubleshooting julia v0.5-dev

Package fails to build

ERROR: Build process failed.

when building MbedTLS, download the file manually (change home directory) and then build the package:

wget --no-check-certificate -O /home/vagrant/.julia/v0.5/MbedTLS/deps/downloads/mbedtls-2.1.1-apache.tgz https://cache.julialang.org/https://tls.mbed.org/download/mbedtls-2.1.1-apache.tgz Pkg.build("BiomolecularStructures")

Note: This a workaround, not a fix for MbedTLS

cmake command not found. installing cmake is required for building from source.

Pkg.test("BiomolecularStructures") failing

ERROR: LoadError: LoadError: LoadError: LoadError: Failed to precompile PyPlot to /home/vagrant/.julia/lib/v0.5/PyPlot.ji

This seems to be an issue of how precompilation of dependencies is handled (see this issue: https://github.com/JuliaLang/julia/issues/14193) and does not happen reliably. Try running julia with --precompiled=yes or try precompiling the failing modules manually, e.g. Base.compilecache("Colors"), Base.compilecache("HttpCommon") and run Pkg.test("BiomolecularStructures") again ### MAFFT test fails under Ubuntu 12.04 LTS If mafft does not work (e.g. the mafft.jl test) and you get this output: `` html correctly installed? mafft binaries have to be installed in $MAFFT_BINARIES or the /build/buildd/mafft-6.850/debian/mafft/usr/lib/mafft/lib/mafft directory.

... you have a broken package. This is fixed in newer Ubuntu LTS releases.

### Note about mafft tests

The mafft tests are disabled for v0.5 as i cannot get them to run reliably (tests fail or pass depending on unknown conditions).

## Changelog

### [0.2.3]

- fixes a bug in the Kabsch module (generated wrong RMSD values). See [#19](https://github.com/hng/BiomolecularStructures.jl/issues/19) for details.

### [0.2.0]

- julia v0.5 compatibility - note: unstable, using the package with v0.5 may require manual fixes, see troubleshooting

### [0.1.0]

- julia v0.4 compatibility

### [0.0.1]

- initial release

A [Bioinformatics WS 2014/15](https://www.uni-due.de/zmb/members/hoffmann/overview.shtml) course project by Simon Malischewski, Henning Schumann. Supervision by [Prof. Dr. Daniel Hoffmann](https://www.uni-due.de/zmb/members/hoffmann/overview.shtml).
