     "Extracting the key-value pairs in a filename can be fully automated when they use a double-separator method. This technique is particularly useful when dealing with variable-length data and keys, a common scenario in scientific data management, including neuroscience research. By embedding key-value pairs in the filename itself, researchers can create self-descriptive files that contain crucial metadata in an organized and accessible format.\n",

     "\n",
     "In scientific research, particularly in fields like neuroscience, it's crucial to have a clear understanding of the data structure you're working with. A schema, or a data model contract, serves as a blueprint for the data, outlining its format and the relationships between different data elements. By defining these contracts explicitly, you ensure that your data adheres to a specific structure, which facilitates more efficient and error-free data processing.\n",
