[gpaw-users] a write problem

[Yuelin Li]

I have this problem:

_______________________________________
Traceback (most recent call last):
   File "testTDDFT.py", line 26, in <module>
     obs.write('bda_fourier.ftd')
   File "/soft/gpaw/gpaw-0.7.2/gpaw/tddft/fourier.py", line 224, in write
     tar = Writer(filename)
TypeError: __init__() takes exactly 3 arguments (2 given)

td_calc.propagate(time_step, iterations, 'bda_dm.dat', 'bda_td.gpw')

obs.write('bda_fourier.ftd')
