RAVE Directory Structure

In iEEG studies, one subject may participate in many different experiments. For instance, the same subject could be asked to perform a working memory task and a language task. These files are collected close in time but must be analyzed differently. RAVE sorts raw data by subject and processed data by project (experiment). The raw data directory structure is the following (where XXX is the base of the data storage directory tree):

 XXX/raw/subject_code/block_number

Where subject_code refers to the individual subject and block_number is a single data acquisition session. In the above example,

XXX/raw/subject_AAA/01
XXX/raw/subject_AAA/02
XXX/raw/subject_AAA/03

Would contain data from three repetitions of a working memory task and

XXX/raw/subject_AAA/04
XXX/raw/subject_AAA/05
XXX/raw/subject_AAA/06

Would contain data from three repetitions of a language task. After preprocessing, data is placed into a new directory organized by project (experiment) followed by subject_code. In the example, it could be:

XXX/data/working_memory_task/subject_AAA
XXX/data/language_task/subject_AAA

To summarize: raw data is placed into raw_dir by the user, then RAVE pre-processes the data and places it into data_dir.
