 to the mat-files folder and loaded automatically if the same measurement dimensions and scanner are used.

 reconstruction, enabled with ``options.useMultiResolutionVolumes``. The extended volume is divided into separate volumes, where the amount depends on whether transaxial and/or axial directions are included. If both are included, there
 will be 6 multi-resolution volumes plus the main volume. The multi-resolution volumes can have larger voxel size than the main volume. This can be controlled with ``options.multiResolutionScale``, where the default value of 1/4 means
 that the original size is divided by this value, i.e. the resolution is 1/4 of the original and the voxel size four times larger. The default extended FOV extension length is 40% (0.4) of the original size per side. With 1/4 scale, this is
