I am embarrassed to be asking this question, but I have exhausted Google
at this point .
I have a number of identically formatted text files from which I want to
extract data, as an example (hopefully, putting these in as quotes will
persevere the format):

At this point, my python script consists of only the following:

import numpy as np
data = []
data = np.genfromtxt("13-7.log", usecols=(1), dtype=None,
skip_header=27, skip_footer=1, encoding=None)
print(data)
np.savetxt('13-7', [data], fmt='%15.9f', header='13-7')
The problem lies in tfe np.savetxt line, on execution I get:

The data is in the data file, but the only entry in '13-7', the saved
file, is the label. Obviously, the error is in the format argument.
Help will be much appreciated.
Thanks in advance.
