Python - How to transform counts in to m/s using the obspy module -


i have miniseed file singlechannel trace , assume data in counts (how can check units of trace?). need transform in m/s. checked obspy tutorial , main problem dont know how access poles , zeros , amplification factor miniseed file. also, need calibration file this?

here code:

from obspy.core import * st=read('/users/guilhermew/documents/projecto/dados sismicos 1 dia/2012_130_doc01.mseed') st.plot()

thanks in advance, guilherme

edit: understood how convert data. obspy has different ways achieve this, comes down removing instrument response waveform data. @robert barsch said, needed file instrument response metadata. came following code:

parser=parser("dir/parser/file") tr in stream_aux:     stream_id=tr.stats.network+'.'+tr.stats.station+ '..' + tr.stats.channel     paz=parser.getpaz(stream_id, tr.stats.starttime)     df = tr.stats.sampling_rate     tr.data = seissim(tr.data, df, paz_remove=paz)

im using seissim function convert data. problem output dosen't right (but cant seem post image)

this question should asked seismology community , not @ stackoverflow! how write obspy user mailinglist?

update: still feel answer he/she should ask directly @ obspy mailing list. however, in order give proper answer actual question: miniseed data format not contain meta information such poles , zeros or used unit. yes need file such resp, sac paz, dataless seed, full seed etc in order station specific meta data. apply seismometer correction read http://docs.obspy.org/tutorial/code_snippets/seismometer_correction_simulation.html

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
