# Naming Conventions

SEEDLingS has 44 subjects numbered 01 - 46. Two subjects dropped out of the study and are not included in the dataset: child 05 and child 24.

At-home data was collected at 12 timepoints, from 06 months to 17 months.

These numbers are concatenated to make a subject-month identifier. Subject 01 at month 06 is written as "01\_06". Both Subject ID and Month use leading zeros, (e.g. "01", not 1, and "06", not 6).

For every subject at every age, there should be an audio and a video recording session (there is one missing audio recording and one missing video recording, see [here](https://seedlings-nouns.bergelsonlab.com/group-1/audio-files) and [here](https://seedlings-nouns.bergelsonlab.com/group-2/video-files)). The full recording ID contains the media type, subject ID, and mont, e.g., "audio\_44\_08", "video\_12\_17".
