File Format Operations for Neuroimaging Data

A collection of methods for handling neuroimaging file formats with separate header and data files (e.g., ANALYZE, NIFTI). These methods provide functionality for file name validation, extension handling, and file path manipulation.

File Format Structure

Neuroimaging formats often use paired files:

• A header file (e.g., '.hdr') containing metadata

• A data file (e.g., '.img') containing the actual image data

Common Operations

• Validating file names against format specifications

• Converting between header and data file names

• Checking file existence and compatibility
