Dear Ashton, Possible: yes... Built-in MSNoise: not yet.... But I will also need it for this project: http://seismologie.be/large-mem/index.html so it's going to be included soon. Let me know if you need help on "hacking" that in the meantime, I'd say the best would be to use jupyter notebooks & the msnoise.api Cheers Thomas Le 16/05/2018 à 02:05, Flinders, Ashton a écrit : > Is it possible to do moving stacks of less than 1 day?

Dear Thomas， Is there any method in “MSnoise” package to remove the average value and linear trend of seismic signal? Best regards, Xi Chaoqiang

two channel types one station

by Flinders, Ashton

I have scanned a database of three stations. One of those stations has two instrument types, HN* and HH*. I wanted to try and use both the seismometer data and the accelerometer data. In my station table I have that station twice, once with the instrument type "HN*" and again with the instrument type "HH*" When calculating the CC, I get an error related to to this section of api.py (1430-1441); if len(st) == 2: mask = np.logical_or(st[0].data.mask, st[1].data.mask) elif len(st) == 3: mask = np.logical_or(st[0].data.mask, st[1].data.mask, st[2].data.mask) # apply the mask to all traces for tr in st: tr.data.mask = mask # remove the masks from the stream st = st.split() return st The error is because st = 4, (HHN, HHE, HNN, HNE). To try and work around, it seems like I can not just tell it in the station conf to not use the HN* station - it still tries to and fails. (1) am I doing something wrong here in general (2) how do I reset the scan archive if I remove this instrument, or do I just have to delete the database and start over?? -thanks -- Ashton F.

Single Station Correlation Issue

by Sergio Morales Méndez

Help! I have 1-station with 3 components following this structure: VERA/HHZ.D/files VERA/HHN.D/files VERA/HHE.D/files and the files have the correct name for the SDS structure, but when i want to make the "ZN, ZE, NE" correlation, i can't get new jobs! only if i want to do AC the software get the jobs for the ZZ correlation. =( -- —— ——— Sergio Morales Méndez Coordinador Área Sismología - Observatorio Volcanológico de los Andes del Sur (Ovdas) www.sernageomin.cl Servicio Nacional de Geología y Minería (56)45 2270701 - Anexo 3328 - @profesergiom Avenida Rudecindo Ortega 03850, Temuco, Chile

instrument code

by Flinders, Ashton

in msnoise admin, configuration > station, what is the correct format for the "instrument" field, and where should I take this from. my responses are not being removed and I have tried using obspy inv, resp files, XMLs and pazs. apologies for the rudimentary question. -a -- Ashton F.
