Note that the below scripts may require some changes due to hardcoded paths. 

Source files:
* rotate.coords.R: used to generate the *_ROTnorm.tsv files
* read.artdata-dialects-new.R: combines the textgrids, articulatory data, 
                           location-, word-, and participant info in one file: art.rda
* read.textgrid.R:  used by read.artdata-dialects.R to parse the PRAAT textgrid files
* dataCreationPaperPackage.R: changes art.rda via subdatD.rda and subdatCVC.rda to make it suitable 
                            for the paper package, among others it adds the formant measures 
                            (see formantDataCreation.R)
* formantDataCreation-new.R: generates the formant trace and stores it in afall.rda, then it
                         normalizes the formants (using Lobanov, 1971) and only includes
                         the formants of the vowels.

Data files:
* dat.rda: file used for the analysis (subset of columns)
* art.rda: articulography data file including segmentation info on the basis of textgrids
* afall.rda: automatic formant trajectories of the audio files
* mfall.rda: manual formant trajectories of the audio files
* vow.norm.rda: normalized formant trajectories for the vowels
* vow.norm.man.rda: normalized manual formant trajectories for the vowels

Text files:
* Articulography_participantinfo_R.txt: participant information
* locationinfo.txt: location information
* wordinfo.txt: word information

Folder:
* intermediary: some intermediary files generated by the scripts
