You also need to edit your PATH variable to include a directory with sox.exe (for example: C:\Program Files (x86)\sox-14-4-1 ), a directory with the R executables (for example: C:\Program Files\R\R-2.15.3\bin\x64 ), and a directory with praatcon.exe. Directories in the Windows PATH are separated by semi-colons.

Finally, when you run FAVE-extract, include windowsPC=T in your configuraton file.

## III. Usage ##

Currently, extractFormants is set up so that it must be run from the main directory of the extractFormants package. To run extractFormants, three arguments are required: the WAV file containing the speech data, the TextGrid file containing the alignments, and the name of an output file for the extracted formants. So, in the directory extractFormants/, type:

`remeasurement` | Specifies whether a second pass is performed on the data, using the speaker's own system as the base of comparison for the Mahalanobis distance. Only used if `formantPredictionMethod=mahalanobis`.
`candidates` | Specifies whether the list of candidate formant values are included in the output. Only used if the `outputFormat=text`.
`vowelSystem` | If set to `Phila`, a number of vowels will be reclassified to reflect the phonemic distinctions of the Philadelphia vowel system (tense short-a etc.).
`windowsPC` | Must be set to `T` to use FAVE-extract on Windows systems.
