function data = mhd_read_image('VSD.Brain.XX.O.MR_Flair.54193.mha');
 function data = mhd_read_image('VSD.Brain.XX.O.MR_Flair.54193.mha');

We'd need to see the whole m-file and know what version/release of MATLAB you're using. Do you have a function declaration after a script in the same file? It's allowed in recent versions but not in earlier versions.

sir am beginner to matlab just before some days, currently i want to be assure my data-sets are correct....means am downloaded dataset from BRATS and i wanna to see i use MATLAB 2015a, so send me the full m-file if its possible or if anyone has MRI brain data-set please share.

Do not put the word "function" at that location.

You need to go to https://www.mathworks.com/matlabcentral/fileexchange/29344-read-medical-data-3d and click on the download link. Unzip the file into any convenient directory that is not underneath your MATLAB installation directory. Use the MATLAB pathtool command to add that directory to the MATLAB path. After that you can invoke,

data = mhd_read_image('VSD.Brain.XX.O.MR_Flair.54193.mha')

Did you try it? Simply type

pathtool

in the command window and press Enter.
