getting the error "Conversion to logical from string is not possible" while using UI table

I use the following functions to make and allow my UI table to be editable.

function UpdateUITable(app, subsystem)

         % Return the initial logical values for checkboxes
    app.IndvCal = false(size(subsystem.ChannelNames));
    
    %Channels = cellstr(string(subsystem.ChannelNames));
    app.Channels = string(subsystem.ChannelNames);

    % Create a cell array with channel names and logical values for the checkboxes
    UIData = [app.Channels, app.IndvCal];

    % Set the CellEditCallback for the UITable
    app.UITable.Data = UIData;

end

function UITableCellEdit(app, event)

    indices = event.Indices;
    newData = event.NewData;

    % Update the logical array based on checkbox changes
    app.IndvCal(indices(1)) = newData;

    % Update the selected channels variables
    app.SelectedCal = app.Channels(app.IndvCal);
    app.SelectedChannels = app.Channels(indices(1));


    % Call the function that uses the selected channels (e.g., data calibration)
    updateChannelMeasurementComponents(app)
end

I use these values to determine what data that I have will be calibrated with the following function. I am getting this logical string error and I am unsure why. I want the channels that are selected to be displayed in my graph

function updateLivePlot(app)
   % Update the live plot
   if isempty(app.DataFIFOBufferch1) || isempty(app.SelectedChannels)
       return
   end
   % Disable interactivity
   disableDefaultInteractivity(app.LiveAxes);
   % Keep the colors the same after each new data point
   app.LiveAxes.ColorOrderIndex = 1;
   if isempty(app.LivePlotLine)
       % First-Time Setup
       app.LivePlotLine = plot(app.LiveAxes, app.TimestampsFIFOBuffer, app.DataFIFOBufferch1(:, app.SelectedChannels));
   else
       % Update existing plot
       for j = 1:numel(app.SelectedChannels)
           % Check if the line needs to be extended
           if numel(app.LivePlotLine) < j || isempty(app.LivePlotLine(j))
               % Use existing axes to plot
               app.LivePlotLine(j) = plot(app.LiveAxes, app.TimestampsFIFOBuffer, app.DataFIFOBufferch1(:, app.SelectedChannels(j,1)));
           else
               % Update existing line
               set(app.LivePlotLine(j), 'XData', app.TimestampsFIFOBuffer, 'YData', app.DataFIFOBufferch1(:, app.SelectedChannels(j,1)));
           end
       end
   end
   if numel(app.TimestampsFIFOBuffer) > 1
       xlim(app.LiveAxes, [app.TimestampsFIFOBuffer(1), app.TimestampsFIFOBuffer(end)]);
   end
end

and the graph plots the calibrated and raw data based on the following function. The data feeds into all function continously atm and when channels are selected in the UI table that (in theory) change what is being displayed on the graph. I am wondering If i should add another column to my UI table that can be another logical that would keep track if the channel is off or on and also keep the calibration logical?

function calibratedData = calibrateData(app,data, slopes, intercepts)
% Calibrate the data using slopes and intercepts
calibratedData = data;

for j = 1:numel(app.SelectedChannels)
    if app.SelectedChannels(j,1) == true 
        calibratedData(:,j) = calibratedData(:,j) * slopes(:,j) + intercepts(:,j);
    elseif app.SelectedChannels(j,1) == false
        calibratedData = app.data; 
        app.TimewindowEditField.Value = 10;
    else
        calibratedData = app.data; 
    end
end
end

Thanks

I also have the following in my startupFCn

app.UITable.ColumnFormat = {'char', 'logical'};
app.UITable.ColumnEditable = [true, true];

not sure if this could be making it harder but I thought I should put it in

    app.Channels = string(subsystem.ChannelNames);

app.Channels will store channel names

    app.SelectedChannels = app.Channels(indices(1));

app.SelectedChannels will hold one of the channel names.

    if app.SelectedChannels(j,1) == true

There you try to compare the channel name to the logical value true

[Connor]

the error that I am getting is on the

app.IndvCal(indices(1)) = newData;

line in the callback function. Do you know why that error would be occuring there?

I also thought that

app.Channels(indices(1));

would indicate the column of app.Channels? How could I makee it so then it will hold all the channel names? and do you think I should create another varibale that uses numel(app.channels) to hold the number of channels selected?

the

if app.SelectedChannels(j,1) == true

was suppose to be

if app.SelectedCals(j,1) == true

thanks for catching all of those!

I am also having some difficulty understanding what to do with UITable cell edit. I have had some trouble understanding how to correctly call for columns and/or rows
