HASE

Framework for efficient high-dimensional association analyses.

Speed test

run_ExampleStudy.sh script runs example of association study with 20.000 SNPs, 1000 phenotypes and 1000 subjects. It runs analysis by chunk of 5000 SNPs (which you can define in config.py file). Standard output looks like this:

START regression mode...

There are 1000 ids and 1000 columns

Installation HASE

Navigate to directory where you want to install HASE and clone this repository: git clone https://github.com/roshchupkin/hase.git

Update HASE

You can update HASE to newest version using git. Navigate to your HASE folder (where you cloned git repository):
git pull

Installation requirements

Your system might already satisfied requirements, we suggest first try to run test example from Testing header below.

  1. HDF5 software (python packages tables and h5py require this installation). If it is not installed on you system, you can download to your home directory the latest source code hdf5.

    tar -xf ~/hdf5-1.8.16.tar.gz
cd ~/hdf5-1.8.16/
./configure 
make 
make install

    Then you need to add one line to your .bachrc or .bash_profile file in your home directory.

    export HDF5_DIR=~/hdf5-1.8.16/hdf5/

  2. BLAS and LAPACK linear algebra libraries for scipy and numpy.

    sudo apt-get install gfortran libopenblas-dev liblapack-dev

    If this does not work or raise errors, then you might need to follow instruction from scipy website.

  3. You need to install python. You can download python from official website python or install one of the python distribution for scientific research, such as Anaconda, Enthought Canopy or Python(x,y). And then you need to install (or first uninstall) scipy and numpy python libraries.

    pip install scipy 
pip install numpy

    To check linkage in numpy:

    python
>>> import numpy as np
>>> np.__config__.show()

    And you should see something like this:

    lapack_opt_info:
  libraries = ['openblas', 'openblas']
  library_dirs = ['/cm/shared/apps/openblas/0.2.9-rc2/lib']
  language = f77
blas_opt_info:
  libraries = ['openblas', 'openblas']
  library_dirs = ['/cm/shared/apps/openblas/0.2.9-rc2/lib']
  language = f77
openblas_info:
  libraries = ['openblas', 'openblas']
  library_dirs = ['/cm/shared/apps/openblas/0.2.9-rc2/lib']
  language = f77
blas_mkl_info:
NOT AVAILABLE

  4. Install python packages listed in requirements.txt file. (you can use package manager which comes with your python pip or conda to install packages):

    • bitarray
    • argparse
    • cython
    • matplotlib
    • scipy
    • numpy
    • pandas
    • h5py
    • tables

Testing

  1. Navigate to HASE directory and type python hase.py -h, you should see help message.
  2. Navigate to HASE directory and type sh run_ExampleStudy.sh, it should start running toy example of high-dimensional GWAS.
