File

Open: Open file. Browse Windows directories to select and open a waveform file. Multiple files can be opened simultaneously. Select files for viewing, analysis and editing by clicking on tabs at base of Waveform Interface.

Save Peak Info: Save data output from waveform shape analysis. This comprises: 1, Summary data (EOD, Sample Rate, Bits, Trigger); 2, Timing, Duration, Amplitude and Area of each Segment of each Phase; 3, current settings for General Preferences and Set Constants. See Analyze Waveform Shape for further details.

Save As: Save file (with all modifications since opening) in the same format as it was opened. PC99 Files are saved in original format as .prn files. Sound Files are saved in original format as .txt files. See Compatible File Formats for further details.

Save EOD Plot: Save waveform data for plotting from a spreadsheet program. The Data Array is modified to begin 0.5 ms before the Start of the EOD waveform. This tool facilitates multiple plots of waveforms from files in which the start of the waveform is not at a fixed position. Data is exported in two columns: left (timing value in ms); right (amplitude).

Save Derivative: Save Derivative data series of the Data Array. Data is exported as a column of derivative values, each one separated in time by the interval between successive Sample Points.

Save Derivative Plot: Save Derivative data series for plotting from a spreadsheet program. The printed Data Array is modified to begin 0.5 ms before the Start of the EOD waveform. This utility facilitates plotting the derivative series and waveform together and plotting multiple derivative series (see also Save EOD Plot). Data is exported in two columns: left (timing value in ms); right (derivative values).

Save Sound: Convert files in PC99 .prn format to Sound Files. If the Sampling Frequency (Sample Rate) is changed using Change Sampling Rate to a compatible sample rate the waveform can be opened and played back in CoolEdit TM or similar audio editing programs. See Compatible File Formats and Save for further information.

Close Graph: Close waveform file currently selected for viewing.

Close All Graphs: Close all opened waveform files.

Print: Print waveform and graphics displayed in Waveform Interface and a text summary including: file name, Sample Rate, Bits and the data fields for Duration, Amplitude and Area of each waveform Phase.

Exit: Close Electric Fish Waveform Analyzer. All options (see General Preferences, Set Constants, Colors) will be retained on subsequent opening.
