Hi Siri,
I gather from the code snippet that you are trying to pull the ‘label’ values from ‘fields.mat’ and use it in ‘ElectrodesDynamicTable’.
Here is the code for doing the same:
numShanks = 1;
numChannelsPerShank = 8;
% Assuming 'fields' is stored in a file named 'fields.mat' and is a cell array
% Load 'fields' from the file
load('fields.mat', 'fields'); % Make sure 'fields' is the correct variable name in your .mat file
ElectrodesDynamicTable = types.hdmf_common.DynamicTable(...
'colnames', {'location', 'label'}, ...
'description', 'all electrodes');
Device = types.core.Device(...
'NeuroOmega', 'NeuroOmega', ...
'Alpha Omega', 'Alpha Omega' ...
);
nwb.general_devices.set('array', Device);
for iShank = 1:numShanks
shankGroupName = sprintf('shank%d', iShank);
EGroup = types.core.ElectrodeGroup( ...
'description', sprintf('electrode group for %s', shankGroupName), ...
'location', 'GPi', ...
'device', types.untyped.SoftLink(Device) ...
);
nwb.general_extracellular_ephys.set(shankGroupName, EGroup);
for iElectrode = 1:numChannelsPerShank
% Ensure 'fields' has enough entries for each electrode
if iElectrode <= length(fields)
label = fields{iElectrode}; % Access the corresponding label from 'fields'
else
label = sprintf('Electrode%d', iElectrode); % Fallback label if 'fields' is shorter than expected
end
ElectrodesDynamicTable.addRow( ...
'location', 'GPi', ...
'label', label);
end
end
ElectrodesDynamicTable.toTable()
nwb.general_extracellular_ephys_electrodes = ElectrodesDynamicTable;
Here is the output of executing the above code :
