Agreed. If you set corr_duration to 1800 and leave analysis_duration
in the standard 86400, this is exactly what you get in the 1-Day
stacks.

As I mentioned, if you set analysis_duration to 3600,
then you only use 1 hour of data each day and leave the rest
untouched… Try it for yourself with the keep_all option enabled and by
looking at the data in the h5 files.

Hi There,

There is actually a test dataset in MSNoise. Just run 'msnoise test' in an
empty folder.

But yes, Julie, You have to populate the database first, right after the
'msnoise install' run.

Cheers,

Aurelien

A tut with small dataset would be useful indeed...Anyway, I think your problem 
is, that you did not populate the station table.

http://msnoise.org/doc/workflow.html#module-msnoise.s002populate_station_table


afaik you will have to do it manualy, since there is a bug in 1.4 version from 
the web interface.

Hi !

I would like to use MSNoise and was wondering if you had, in addition to the 
documentation on your website, a tutorial with a small dataset.
Actually, I’ve installed MSNoise on my Mac with SQLite, see the web interface 
but as soon as I try to create a station list I get an error message :
builtins.TypeError

TypeError: __init__() missing 8 required positional arguments: 'net', 'sta', 
'X', 'Y', 'altitude', 'coordinates', 'instrument', and 'used'


I’m not very familiar with Python so I don’t know if it’s because I’ve missed 
something in the way I use MSNoise (parameters to change/ files to be present 
in the project folder…) or if it comes from the installation itself.

Thanks,

Julie
