Hi everyone,
I am testing release 1.3.1 on Ubuntu 64bit (12.04). Things went pretty smooth for a first
attempt with some CCF being calculated. Except every now and again the msnoise compute_cc
stops working delivering the error message below, apparently linked to sampling rate
issues?
Here’s a link to a SDS data structure with data (two stations/two days) that generated the
error:
https://copy.com/blzIarTs4QrAllNr
I have kept most options in the config default, just for testing purposes, except start
and end date to match my data. I also added a filter in the config window (0.1 (low)- 0.3
(mwcs low)- 0.9 (mwcs high) -1.1 (high) Hz, 100 (RMS threshold), 1 (window), 0.5
(step)).
msnoise compute_cc did not work unless a filter was defined in the configuration. I had 27
days worth of CCF's computed that I could plot, thus, I suppose the general config
was ok? The computed CCF’s were what i expected (matched another workflow I use for
ambient noise).
Any hints? The data files look ok as far as I can tell but there may be something I am
missing?
I am now testing with a different dataset to see whether problems are with data files.
Thank you.
Ciao,
Silvio
