Re: [MSNoise] Stuck in Compute_cc step

Hi Thomas, before talking about my problems, I’d like to introduce my data, and the configurator’s “configuration” I use. I study mining data. The scale is totally different from the initial purpose of Msnoise, and I think is one of the reasons of a lot of problem I’m facing.. There are 3 stations, which are around 200 meters away from each other, and at the same altitude. They record data with a 200 Hz samplerate. In my database, I’ve chosen for each station 2 days of recording (the end of the first day does not correspond exactly to the beginning of the second day), with X,Y,Z channels. The length of each records is approximatively 24 hours. Here’s the structure of my database folder (all files are SAC files) : LF1.AN..X.2011.003 LF1.AN..Y.2011.003 LF1.AN..Z.2011.003 LF1 LF1.AN..X.2011.004 LF1.AN..Y.2011.004 LF1.AN..Z.2011.004 LF2.AN..X.2011.003 LF2.AN..Y.2011.003 LF2.AN..Z.2011.003 AN LF2 LF2.AN..X.2011.004 LF2.AN..Y.2011.004 LF2.AN..Z.2011.004 LF3.AN..X.2011.003 LF3.AN..Y.2011.003 LF3 LF3.AN..Z.2011.003 LF3.AN..X.2011.004 LF3.AN..Y.2011.004 LF3.AN..Z.2011.004 The configurator I use (only the inserts which are (I guess) important for compute_cc : startdate : 1970-01-01 enddate : 2100-01-01 analysis duration : 86400 cc_sampling_rate : 200 resampling_method : Decimate decimation_factor : 2 preprocess_lowpass : 1 preprocess_highpass : 80 maxlag : 120 corr_duration : 1800 windsorizing : 3 crondays : -1 autocorr : N keep_all : Y keep_days : Y ref_begin : -100 ref_end : 0 export_format : BOTH sac_format : doublets The filter configuration I use : low : 10 mwcs_low : 10 high : 80 mwcs_high : 80 rms_treshold : 0 mwcs_len : 10 mwcs_step : 5 My problems : The folder CROSS_CORRELATIONS is created, as well as the STACK folder. Problem 1 : When I plot the mseed files in CROSS_CORRELATION, i get nothing… the files are not empty (324 Kio), but there’s nothing in the plot window. Problem 2 : When I plot the SAC (or MSEED) file in STACKS/00/001_DAYS folder, here is what I get : It’s indeed a symmetric signal… which looks more like an autocorrelation, doesn’t it ? Here’s what I get if I zoom on it : Thanks for your help Thomas. Sébastien. PS : I had to change for each file in its header, the name of the station, and the component, which were false (thanks to the mining data). Do you think it can be the source of any bug ?
