Could Someone help me? Thanks!
When I run the python program,the console shows: 
  File "Report.py", line 163, in <module>    ProcessEnergy(infiles,summaryDoc,detailedDoc,StartCut)  File "/home/darwin/simulation/analysis/Energy.py", line 83, in ProcessEnergy    (mean,var,error,kappa)=stats.Stats(data[StartCut:-1])  File "/home/darwin/simulation/analysis/stats.py", line 68, in Stats    mean=sum(x)/(N+0.0)  File "/usr/local/lib/python2.7/dist-packages/numpy/core/fromnumeric.py", line 1453, in sum    return _wrapit(a, 'sum', axis, dtype, out)  File "/usr/local/lib/python2.7/dist-packages/numpy/core/fromnumeric.py", line 37, in _wrapit    result = getattr(asarray(obj),method)(*args, **kwds)TypeError: cannot perform reduce with flexible type

Could someone tell me what's wrong with that?
