fastSTRUCTURE, errors when run distruct.py

[zhangd...@126.com]

I am using fastSTRUCTURE, it performs quite well. But I got troubles in the last step for generating a Distruct plot.

Here is my command:
python distruct.py -K 3 --input=plink_simple --popfile=pop --output=plink_simple_distruct.svg

and here is the program reporting error:

File "distruct.py", line 169, in <module>
figure = plot_admixture(admixture, population_indices, population_labels, title)
File "distruct.py", line 15, in plot_admixture
figure = plot.figure(figsize=(5,3))
File "/home/yin/bin/anaconda/lib/python2.7/site-packages/matplotlib/pyplot.py", line 435, in figure
**kwargs)
File "/home/yin/bin/anaconda/lib/python2.7/site-packages/matplotlib/backends/backend_qt4agg.py", line 47, in new_figure_manager
return new_figure_manager_given_figure(num, thisFig)
File "/home/yin/bin/anaconda/lib/python2.7/site-packages/matplotlib/backends/backend_qt4agg.py", line 54, in new_figure_manager_given_figure
canvas = FigureCanvasQTAgg(figure)
File "/home/yin/bin/anaconda/lib/python2.7/site-packages/matplotlib/backends/backend_qt4agg.py", line 72, in __init__
FigureCanvasQT.__init__(self, figure)
File "/home/yin/bin/anaconda/lib/python2.7/site-packages/matplotlib/backends/backend_qt4.py", line 68, in __init__
_create_qApp()
File "/home/yin/bin/anaconda/lib/python2.7/site-packages/matplotlib/backends/backend_qt5.py", line 138, in _create_qApp
raise RuntimeError('Invalid DISPLAY variable')
RuntimeError: Invalid DISPLAY variable


Am I install something wrong?

Thanks a lot for your attention, looking forward to your reply very much!
sincerely,
Zhang

First try with the example data provided with the script.  If you can't get that working, there is a problem with the Python installation.

Almost the same errors when input example data.

You said there maybe some problems with python,

Is there any preconditions for running distruct.py? because I only installed fastStructure followed the manual page.

You may be missing some python modules.  Check the github page for all things that need to be properly installed.
