Minimal Package for computing SARA

Install

pip install bottleneck
pip install https://github.com/ThomasLecocq/minimal_sara/archive/master.zip

Operation

Create a project folder
Create the config.ini file containing:

# This is a template msara config file
[ "msara" ]
data_folder = "C:\Users\thlec\Desktop\testSDS"
data_format = SDS

network = YA
location = "00"
channel = HHZ
stations = UV05, UV06, UV10
startdate = 2010-01-01
enddate = 2011-01-01

bandpass = 5,15
env_sampling_rate = 1
smoothing = 600, 86400

run "msara init"
run "msara scan_archive"
run "msara envelope"
run "msara ratio"
run "msara plot"

Alternatively, if the archive is not properly structured (bad file naming, etc), you can replace step 4. with a direct call to a path:

msara scan_archive --path C:\Users\thlec\Desktop\VOLCANO\IDDS

This path will be scanned, recursively (all folders will be read) and files will be read, and if the tr.stats.station match what is configured in config.ini and if the tr.stats.sampling_rate is larger than twice the freq_max of the badnpass (in the config.ini above, it's 15, so traces with sps > 30 Hz will be accepted).
