Dear users, long time from my last mail.. I have this small issue ( I hope) when I run the CCs: 2017-01-17 13:04:50 [INFO] *** Starting: Compute CC *** 2017-01-17 13:04:50 [INFO] Will compute ZZ 2017-01-17 13:04:51 [INFO] New CC Job: 2010-01-02 (1 pairs with 2 stations) Process Process-1: Traceback (most recent call last): File "/home/carmelo/anaconda/lib/python2.7/multiprocessing/process.py", line 258, in _bootstrap self.run() File "/home/carmelo/anaconda/lib/python2.7/multiprocessing/process.py", line 114, in run self._target(*self._args, **self._kwargs) File "/home/carmelo/anaconda/lib/python2.7/site-packages/msnoise/s03compute_cc.py", line 430, in main basetime, tramef_Z = preprocess(db, stations, comps, goal_day, params, tramef_Z) File "/home/carmelo/anaconda/lib/python2.7/site-packages/msnoise/s03compute_cc.py", line 355, in preprocess return basetime, tramef_Z UnboundLocalError: local variable 'basetime' referenced before assignment Before modify the code to find a solution by myself I would like know if someone already had the same issue and if yes what can be the easy solution. cheers and thanks, ----------- Mr Carmelo Sammarco MSc BSc FGS PhD Student in Geology and Petroleum Geology The University of Aberdeen is a charity registered in Scotland, No SC013683.

multiprocessing CC error

by 王力伟

Dear Thomas, Thanks for your replay. There are just a few errors like that. It is rare, I checked those sac data with error, picked them out , and rerun, It seems all right. However, There are many gaps, pulse calibration and earthquake signals in those sac data. Bellow is the link to the access of those data mentioned before. OneDrive share links: https://1drv.ms/f/s!ArWfPHWmchfDlWAgc2ho7BDgMbvP Best wishes! Wang Liwei.

multiprocessing CC error

by 王力伟

Thomas and msnoise users, Have you ever across the multiprocessing CC error when you calculate the CC functions? When I just use the ZZ components, Sometimes this error happen, Sometimes it's not. I checked the SAC file and modified the Calibration factor to 1.0, but it's still happens, So it should not the problem of the data and SAC header. I appreciate in advance for any help.
