3. [Use labels obtained from>Backfitting prototypes to EEG>Ok]

#### Expected behavior: [*To get the microstate statistics of duration, occurrence etc.*]
#### Actual behavior: [*Error message pop-up*]
#### Versions

OS version	[Windows 11 23H2]

Yes I am having a similar issue but with running any EEGlab function that uses 'nanmean' instead of 'mean' with the argument 'omitnan'. I just updated my matlab to 2026a, and my EEGLab is the most recent version as well (2026.0.0). Any time I try to run my preprocessing function that calls to EEG lab I get the following error:

Unrecognized function or variable 'nanmean'.
