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

Hi Silvio,
I have noticed this error too... I haven't had time to check it, but it
happens when we try to merge two traces that need merging...
it's definitively a bug :-)

Hi all,
I observed the same error from time to time to, and I think it has already
been rised in previous discussions.
My guess (but I never checked) is that it is a rounding error which leads
to have 1 extra or missing sample when merging or resampling. You then
obtain a sampling frequency which is not exactly the expected one, and
obspy refuses to merge the traces.

Aurélien,
actually, there shouldn't be any rounding involved when merging... but
an issue could come from the sample alignment procedure, when samples
are not aligned on the sampling grid (a file starting at 0.005 seconds
for a 100Hz data)..

(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.

Aurélien,
actually, there shouldn't be any rounding involved when merging... but
an issue could come from the sample alignment procedure, when samples
are not aligned on the sampling grid (a file starting at 0.005 seconds
for a 100Hz data)..

Hi all,
I observed the same error from time to time to, and I think it has
already
been rised in previous discussions.
My guess (but I never checked) is that it is a rounding error which
leads
to have 1 extra or missing sample when merging or resampling. You then
obtain a sampling frequency which is not exactly the expected one, and
obspy refuses to merge the traces.

http://mailman-as.oma.be/mailman/listinfo/msnoise Hi Silvio,
I have noticed this error too... I haven't had time to check it, but it
happens when we try to merge two traces that need merging...
it's definitively a bug :-)

http://mailman-as.oma.be/mailman/listinfo/msnoise 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.
