Hi,
Thanks,
I fix it, it works.
SAC is nice because of the metadata coming with the data. For a correlation
file, the possibility to have the event coordinates as well as the station
coordinates in the header is very convenient because you can fill the event
coordinates with STA1 coordinates and station coordinates with STA2
coordinates. So distance, azimuth and back-azimuth are easily (and
automatically) computed.
And I developed a code to automatically compute group velocity dispersion
curves from CC, which reads the distance between the stations in the
header, without the need of other metadata file. ;)
Cheers,
Aurelien

Hi Thomas,
Great job for the 1.3.1 MSNoise version!
Thanks!
I have however encountered a problem when computing the MWCS: the function
only takes Miniseed files as input, which is no compatible with the fact
that you can save the CC as SAC files.
Aha ! Indeed... Why would one still work with SAC anyway :-)
Until I provide a bugfix, hack the code at two places:
https://github.com/ROBelgium/MSNoise/blob/master/msnoise/
s05compute_mwcs.py#L109
and
https://github.com/ROBelgium/MSNoise/blob/master/msnoise/
s05compute_mwcs.py#L115
Let me know,
Tom
Here is the error below.
Cheers,
Aurelien
