Issue when reading channel locations from Brainstorm file with empty SCS field

[nguyen-td]

Description

Similar to #761 but the current version throws the error Index exceeds the number of array elements. Index must not exceed 0. when the elocIn.SCS field is empty. I am trying to convert this Brainstorm chanlocs file into EEGLAB's chanlocs format.

Extending

eeglab/functions/sigprocfunc/readlocs.m

Line 426 in 02a306c

if isfield(elocIn.SCS, chans{iChan})

by if isfield(elocIn.SCS, chans{iChan}) && ~isempty(elocIn.SCS.(chans{iChan})) will fix it.

Steps to Reproduce

1. Download the Brainstorm chanlocs here
2. Run readlocs('channel_BrainProducts_ActiCap_97.mat');

Versions

OS version	macOS Sonoma 14.3
Matlab version	R2024a
EEGLAB version	dev
