Explosions Detector

To run the explosions detector:

  1. Download the Explosions-Detector and Triton folder and add it to your computer.
  2. Open up MATLAB and add the Explosions-Detector and the Triton folder to your path. Make sure that Triton is in your MATLAB path as well otherwise you will probably get a MATLAB error:

Undefined function 'utFindFiles' for input arguments of type 'cell'. Error in xcorr_explosion_p2_v3 (line 26) [PathFileList, FileList, PathList] =

  1. Open the script "xcorr_explosion_p2_v4.m" from the Explosions-Detector file folder.
  2. Important lines to edit within the script are:
  • Line 18: Selects the input folder with all of the .xwav files to run through the detector.
  • Line 19: Saves and names the detector files to a different folder than the input folder.
  • Line 27: Makes sure that the pathway to the explosion template is correct (this template .mat file is saved in the explosions detector code folder).
  1. Hit run, selecting the df20 folder containing the xwav files.
  2. The detector will begin. Detection mat files are generated in an "Explosions" folder created in the df20 folder.

After running your detections through GPL Review (https://github.com/ScrippsWhaleAcoustics/GPLReview), if you want to convert the detection mat files into times when airguns occurred, use merge_explosions_one_file.m

Note: You will have to convert these times from CVS format to a date format in Excel!
