[MSNoise] error in pws

[孙杰]

Hi, Thomas
   I'm Sun Jie , very sorry to sent you email twice due to some problems in my first email system.
Following your suggestion, I have solved the autocorrelation plotting problem ,many thanks!
  However, i have another question about pws stacking. I 'config' the stack_method=pws ,pws power=2 , pws_timegate=10.0,autocorr=Y,ZZ=Y....,
There is following error when I 'compute_cc'. How can i solve this problem? many thanks!

$ msnoise compute_cc
result in
