hi again, Thank you for your reply. I have used the Python 2.5.X and haven't encountered any problem.But, I changed with='lines' to wl, when I use the Python 2.6 I'm getting the following error,
File "/usr/lib/python2.6/dist-packages/Gnuplot/PlotItems.py", line 146, in set_option raise Errors.OptionError('%s=%s' % (option,value)) Gnuplot.Errors.OptionError: wl=lines so, I have used the Python 2.5. Finaly, I want to ask a question about Band-structure example. I have calculated the Band-structure folder for Exercises-Lyon07->Day-1->Problem-Si in the siesta-tutorials. When I run the "bands.py" file I'm getting the following error, gnuplot> plot "/tmp/tmp_m2JpT.gnuplot/fifo" notitle with lines -1 ^ line 0: ';' expected Then, I changed with='lines -1' to with='lines 1' the 144, 149 and 172 lines. I think that I'm getting the Band-structure without problems. Do these lines changes lead to a problem in the band graphics? Regards.
