Hi. I have a file of spherical particles saved by function of pack.SpherePack().save(). It has the format as follows, 

0.000919246 0.000859971 0.000602774 1.20067e-05 -1
0.000959836 0.00055149 0.000975021 2.11065e-05 -1
..... 

I want to translate all the particles in x direction and conduct it by the following python code,  
=======================================
=======================================
import numpy as np 

data = np.loadtxt('initial_spheres.txt', delimiter=' ', skiprows=0)

with open('initial_spheres_translate_x.txt','w') as fd:
    for i in range(len(data)):
        fd.write('%.9f %.9f %.9f %.5e %d\n' % (data[i,0]+0.5e-3, data[i,1], data[i,2], data[i,3], -1))
=======================================
=======================================
 and i got the data as this, 

0.001919246 0.000859971 0.000602774	1.20067e-05 -1
0.001959836 0.000551490 0.000975021	2.11065e-05 -1

The format seems the same, however, there is an format error when reading the file by pack.SpherePack().load() function.  
By the way, i have tried the delimiter as space and tab and both don't work. 

Thanks.
