Hello @kissadamfkut
This is potentially unrelated to your commit but I am seeing an issue in the load lines from the function below the typo you modified, so I was wondering if you ran into any additional problems when you noticed the typo.

The issue I get is coming from the following load lines in eyeCatch:

eye-catch/eyeCatch.m

Lines 36 to 38 in b203535

	load('pooledEyeScalpmap.mat'); % load pooledEyeScalpmap varaible
	load('eyeChannelWeightNormalizedPart1.mat'); % load eyeChannelWeightNormalizedPart1 variable
	load('eyeChannelWeightNormalizedPart2.mat'); % load eyeChannelWeightNormalizedPart1 variable

Warning: Variable 'pooledEyeScalpmap' originally saved as a scalpmap cannot
be instantiated as an object and will be read in as a uint32.

(The pooledEyeScalpmap.mat file itself is quite big, >90M, but the loaded uint32 variable is tiny in comparison, just 6x1 uiint32, so it doesn't seem to import correctly).

I was wondering if the loading worked ok for you?
