Snippet for loading a gnuradio data file into python

gnuradio_data.py

import scipy
import re

data = scipy.fromfile(datafile, dtype=np.float32)

a = re.compile("ra(.*)dec(.*)time(.*).dat")

bandwidth = 4e6
centre = 1420.4e6

filepath = datafile.split('/')

s_ra = float(a.search(filepath[-1]).group(1))
s_dec = float(a.search(filepath[-1]).group(2))
s_time = a.search(filepath[-1]).group(3)

frequencies = np.linspace(centre - bandwidth/2, centre + bandwidth/2, 256)/1e6
data = np.reshape(data, [-1,256])
