You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: fmri_data.m
    path of file: ./repos/CanlabCore/CanlabCore/@fmri_data
    
    the code of the file until where you have to start completion: % fmri_data: Data class for storing and analyzing neuroimaging datasets and associated information
%
% 'fmri_data' is a data class containing information about generic fmri
% datasets stored in a structure-like object.  Using this has the
% advantages that the properties and methods are standardized and controlled.
% It also keeps track of the history of what was done to the da
