[MSNoise] NameError: global name 'gps2DistAzimuth' is not defined

Dear mailing list, I am facing a problem concerning the cc computation step. Specifically, I have an error message about the coordinates of the stations. I am processing the data of two stations. I have already completed the previous steps without any problem. The following is the error that I have when I execute the "s03compute_cc.py" script: _________________________ Traceback (most recent call last): File "s03compute_cc.py", line 335, in <module> cplAz = azimuth(coordinates, X0, Y0, X1, Y1) File "/localstorage/MSNoise/database_tools.py", line 470, in azimuth dist, azim, bazim = gps2DistAzimuth(y0, x0, y1, x1) NameError: global name 'gps2DistAzimuth' is not defined _____________________________________________ I am going to process R and T components, so the coordinates of the stations are inputted in the station table as it is needed. I think that I did it properly. Did anybody face a similar problem? I also attach a screen-shot of the terminal in order to see when exactly the error appears. Thank you very much in advance. Dimitris
