Additional dependencies to build


It is highly reccommended one use Anaconda for Python environment

git clone
cd naga-gwas-rest
make install

Running service in development mode

NOTE: Example below runs the REST service and not the task runner.

# It is assumed the application has been installed as described above
export FLASK_APP=nbgwas_rest
flask run # --host= can be added to allow all access from interfaces

# Service will be running on http://localhost:5000

# NOTE: To have tasks processed must be started in
# another terminal

Example usage of service

Below is a small script that leverages the nbgwas_rest service to run NAGA on the compressed nagadata/schizophrenia.txt.gz passed into the script on the command line

#!/usr/bin/env python

import sys
import gzip
import time
import requests

# pass the gzipped schizophrenia.txt.gz
networkfile = sys.argv[1]

# set parameters
data_dict = {}

# set snp file
files = {'snp_level_summary':, 'rb')}
url = ''
r =, data=data_dict, files=files,

# If successful the previous POST will return 202
if r.status_code != 202:
    sys.stderr.write('Submission failed with code: ' + str(r.status_code) +
    sys.stderr.write('Message: ' + str(r.text) + '\n')

# If successful Location will be set to a URL that can
# be polled for result
if 'Location' not in r.headers:
    sys.stderr.write('Expected Location in Header, ' +
                     'but its not there: ' + str(r.headers) + '\n')

resulturl = r.headers['Location']
getres = requests.get(resulturl, timeout=30)
json_res = getres.json()
while getres.status_code != 200 or json_res['status'] == 'submitted' or json_res['status'] == 'processing':
   getres = requests.get(resulturl, timeout=30)
   json_res = getres.json()

sys.stdout.write(str(json_res) + '\n')

Assuming the above is saved in a file named and run from base directory of this source tree

./ nagadata/schizophrenia.txt.gz

Example output:
