Aggregating recording information

How to gather LENA information from .its files and ELAN annotations

ITS metrics

  1. Set your working directory to Fas-Phyc-PEB-Lab/VIHI/Scripts/LENA_Scripts.

  2. Generate a current list of .its files

    1. Run list_its_files.R. This will generate a new list of all the .its files in Fas-Phyc-PEB-Lab/VIHI/SubjectFiles/LENA and place the list in LENA_Scripts/data.

  3. Run getting_LENA_details_from_its.R. This script will take a long time to run. Eventually, this will generate VIHI_its_details.csv and place it in LENA_Scripts/data.

Being appropriately skeptical about .its tags

Exporting ELAN annotations

  1. Open ELAN.

  2. Navigate to File > Export Multiple Files As > Tab Delimited Text

3. Choose an existing domain, or create a new domain (make sure to include all files in SubjectFiles/LENA/VI, SubjectFiles/LENA/HI, and SubjectFiles/LENA/TD), and then press load. It may take a few moments for the next window to appear.

4. Make the following selections, then when prompted, select "UTF-8" encoding.

5. Save the file to Fas-Phyc-PEB-Lab/VIHI/SubjectFiles/LENA/annotations/all_lena.txt

6. Run ELAN_wrangle.R over the file all_lena.txt. This script is located in Fas-Phyc-PEB-Lab/VIHI/Scripts/LENA_Scripts. This script will output a .csv in Fas-Phyc-PEB-Lab/VIHI/SubjectFiles/LENA/annotations/VIHI_LENA_annotations[today's date].csv
