The error you encountered suggests that the variable data does not exist in the loaded .mat file. The structure of the .mat file may be different from what you expected. To address this issue, you can examine the contents of the .mat file to determine the correct variable name to use.

Here's an example of how you can inspect the contents of the .mat file and find the appropriate variable name:

x = load('female_1.mat');
whos('-file', 'female_1.mat')
