how skip some specific files in multiple subfolders in matlab?

I need to skip some specific files in different sub-folders. for example if the filename not contains string charchters such as raw, info, do some operations.

dirName = 'D:\Neda\Pytorch\CAMUS\training\';
fileList = SureScan_getAllFiles(dirName);

for k = 1:length(fileList)-50

filename = fileList{k};

%if filename not contain 'raw') | 'Info_' | 'sequence.mhd' | '_sequence'    

% do some operation
end
end

if ~contains(filename, {'raw', 'Info_', 'sequence.mhd', '_sequence'})
    % do some operation
end

contains() requries R2016b or later.
