A class representing a four-dimensional brain image, backed by a memory-mapped file. MappedNeuroVec objects store their data in a memory-mapped file, providing efficient access to large brain images without loading the entire dataset into memory. This class inherits from the NeuroVec and implements the ArrayLike4D interface.

Usage
MappedNeuroVec(file_name)
Arguments
- file_name
the name of the 4D image file that containing the memory-mapped data source.
Value
a new instance of type MappedNeuroVec
Slots
filemapAn instance of the mmap class representing the memory-mapped file containing the brain image data.
offsetAn integer representing the offset (in bytes) within the memory-mapped file where the brain image data starts.
