Error loading channel locations from Brainstorm .mat file

Description

I'm trying to import the channel locations from a '.mat' Brainstorm file within EEGLAB for a single participant. When using the readlocs() function, I get an error. I'm using the Leipzig Study for Mind-Body-Emotion Interactions (LEMON) data for participant 'sub-010291' and the EEG data can be accessed from here as a BrainVision file and the channel locations can be accessed from here.

Steps to Reproduce

  1. Load BrainVision EEG files for sub-010291 (from LEMON dataset)
  2. Load channel locations from Brainstorm file (sub-010291.mat)

Expected behavior:

Channel locations loaded successfully

Actual behavior:

EEGLAB error in function readlocs at line 423:
Unrecognized function or variable 'elocBrainstrom'.

Versions
OS version macOS Sonoma 14.3
Matlab version R2023b
EEGLAB version 2024.0*

There was a minor glitch with the readlocs function to read this kind of file. Now fixed in 7fad5e6

readlocs('sub-010291.mat')
readlocs(): 'mat' format assumed from file extension
