Using Set Path to Enable behaviorAnnotator on Matlab for Mac

Trying to use behavior annotator to view Seq files on Matlab. I have never used this program before and am unsure about how to add behavior Annotator. I was told to change the set path environment to enable it but can't figure out what I am supposed to do

Hi Sabine,

I am assuming you are trying to use "behavior annotator" in MATLAB, but MATLAB is not recognizing the custom function. This usually happens because MATLAB cannot “see” the folder that contains the "behavior annotator" code.

To resolve this, you will need to add the folder containing the scripts to MATLAB’s search path.

Open MATLAB -> Home -> Set Path -> Click Add with Subfolders -> Browse to the folder containing necessary files- > Apply & save

You can also refer to below documentation on search path for more details:

Hope this might help!

thank you so much!

Hi Sabine,

As I understand, you want to use the BehaviorAnnotator in MATLAB on your Mac to view .seq files

Adding on to the previous answer with more detail, here’s how you can enable BehaviorAnnotator using the Set Path feature in MATLAB for Mac:

1. Ensure you have the folder containing the BehaviorAnnotator MATLAB files saved somewhere on your Mac.

2. Add the Folder to MATLAB’s Path

1. On the MATLAB toolbar, go to the Home tab.

1. Click Set Path.
2. Choose Add with Subfolders….
3. Navigate to the folder where you saved BehaviorAnnotator, select it, and confirm.
4. Click Save to apply the changes, then Close the window.

Alternatively, you can use a command in the MATLAB Command Window. For example, if your folder is in Documents, you would type:

addpath(genpath('/Users/yourusername/Documents/BehaviorAnnotator'))

savepath

(Make sure to replace /Users/yourusername/Documents/BehaviorAnnotator with the actual path to your folder.)

3. Now, in the MATLAB Command Window, simply type:

BehaviorAnnotator

and press Enter. This should open the BehaviorAnnotator interface.

4. Once the interface is open, use the available options to load and view your .seq files.

If you have any other questions or encounter issues, let me know.
