And did it work?

I'm not sure about the policy regarding attachements on this list but I 
think it would have been better to provide a link than attach it.

Anyways, I've reduced your original script, did a test run and it works 
as expected (at least it shows a plot):

import numpy
import matplotlib.pyplot as pyplot

with open("ourtest_out.list", "r") as f:
     z = numpy.array([float(v) for v in f.readline().split()[1:]])

a = numpy.loadtxt("ourtest_out.list", skiprows=3)
N = 100
Conc = a[1:, N+1:]

print len(Conc[0]) == len(z)

pyplot.figure()
pyplot.plot(Conc[0], z)
pyplot.show()

Do you still get an error?

Bye, Andreas
