I want to thank the users for their invaluable help.
My final error concerns the plotting:
<ipython-input-157-043a2bfb8704> in <lambda>(x, pos)----> 1 formatter
= FuncFormatter(lambda x, pos: "%d" % x/10) 2 3 fig, ax =
plt.subplots() 4 ax.yaxis.set_major_formatter(formatter) 5
a= plt.plot(D.dtrajs[0])
TypeError: unsupported operand type(s) for /: 'str' and 'int'
