how to add fsl to matlab in matlab

To add FSL (FMRIB Software Library) to MATLAB, you can follow these steps:

1. Install FSL on your computer by downloading it from the FSL website (https://fsl.fmrib.ox.ac.uk/fsl/fslwiki/FslInstallation). Follow the instructions provided for your specific operating system.

2. Once FSL is installed, open MATLAB.

3. In the MATLAB command window, type the following command to set up the FSL environment variables and add the necessary paths to MATLAB:

main.m
setenv('FSLDIR', '/path/to/fsl/directory') ;
setenv('FSLOUTPUTTYPE', 'NIFTI_GZ') ;
setenv('PATH', [getenv('FSLDIR') '/bin:' getenv('PATH')]) ;
setenv('LD_LIBRARY_PATH', [getenv('FSLDIR') '/lib:' getenv('LD_LIBRARY_PATH')]) ;

% Add necessary paths to MATLAB
addpath([getenv('FSLDIR') '/etc/matlab']) ;

8 lines

Note: Replace '/path/to/fsl/directory' with the actual path where FSL is installed on your system.

4. Save these changes by creating a file called startup.m in the default MATLAB folder (you can find this folder by typing userpath in the MATLAB command window). Edit the startup.m file and add the previously mentioned commands so that they are executed every time MATLAB starts.

5. Restart MATLAB for the changes to take effect.

After following these steps, FSL should be properly added to MATLAB, and you can start using FSL functions and commands within your MATLAB scripts.

Note: Make sure that the FSL installation directory is correctly specified in step 3 and matches the one you used during your FSL installation.
