  • Cursors can be dragged or set by pressing the "r" and "b" keys (for the red and blue cursors).
  • Tab delimited data can be logged by choosing the "data log" icon or by pressing the "g" key.
  • Frequency at peak spectrum amplitude can be logged or a different peak can be selected.

  • In the Windows OS you must save a *.wav file with sound from each movie you want to analyze. Both files must have the same names (except for the extension)! Select the *.wav file and the movie file (*.mov, *.avi etc.) will open automatically as long as the names are the same. Movie file with sound can be opened directly in Mac OS X.

  • Procedures require BSound2 (latest version), Quicktime, and Igor Pro v5.02 .

  • Place the unzipped "BeakGape.ipf" file in the "User Procedures" folder.
      - Located in the "Igor Pro" folder.
      - The folder containing BSound2 procedures should also be placed here.
  • Open the Procedure window (command-M) and type #include "BeakGape".
      - Type under the line "#pragma rtGlobals=1"
  • Close the Procedure window to compile the procedures.
  • If using the Windows OS, open the 'Settings' panel and enter the extension of the movie file (e.g, .mov, .avi, etc.)
  • Open a movie for analysis using the BeakGape menu.
