Request for help in running REST code

[piyushswami04]

Dear Authors,

Hope you are doing well.

I am a Postdoc at DTU, Demark. I am trying to use your REST code (https://github.com/goodshawn12/REST) for my work. When I ran the test_script.m it worked fine. But, I wanted to see the REST tool. So I uncommented Quick20 settings and REST(Opts). It gave the error shown in the file attached. I also tried using other settings and emotiv. Also, set opts. playback = 0; but it gave the same error.
Can you please help me in running your code?

There seems to be an issue with your attachment.

I may be misreading what you did, but you want opts. playback = 1;, not 0. The Quick20 demo works just fine for me with that. If that isn't the problem, could you share your test_script2.m so I can see exactly what you're trying?

Thanks for your reply Shawn. This is what I did:

1. Copied REST folder and added it to matlab path.
2. Copied the path of BCILAB (i.e., /Users/piyushswami/Documents/MATLAB/mywork/Func/REST/dependencies/BCILAB in this case) in the file bacilab_path.txt and saved it.
3. Ran the following script:

%% Test REST (go to 'REST' folder)
%% set path and initialize bcilab
rest_path = './';
bcilab_path = which('bcilab.m');
if isempty(bcilab_path)
current_path = pwd;
addpath(fullfile(rest_path, 'dependencies', 'BCILAB'));
bcilab
cd(current_path);
addpath(genpath(rest_path));
end

%% refresh workspace
% clear all will break bcilab and require it to restart as it uses global variables
close all hidden
clearvars -except rest_path
timer = timerfindall;
if ~isempty(timer)
stop(timerfindall); delete(timerfindall);
disp('Delete timers...');
end

You have both the Quick20 and Smarting settings active. Try commenting out the Smarting settings if you're trying to run Quick20.

Ok, I tried the following but got the same error message.

Can you please let me know if you could update test_script.m which worked for you or share it with me on [email protected]?

[lucapton]

I'm sorry to say that the code you shared works for me. Perhaps it has something to do with the newer versions of matlab. I'm testing on 2019a (the only version I have available) while you're on 2021a. I'm not sure what else to do.

[piyushswami04]

Hi,
Thanks for checking. I switched to matlab 2019a and ran the above code. It gave this error:
Dot indexing is not supported for variables of this type.

Error in env_translatepath (line 80)
filename = [tracking.paths.dependency_path filename(1+length('dependencies:'):end)];

Error in REST>REST_OpeningFcn (line 115)
handles.lsllib = lsl_loadlib(env_translatepath('dependencies:/liblsl-Matlab/bin'));

Error in gui_mainfcn (line 220)
feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});

Error in REST (line 71)
gui_mainfcn(gui_State, varargin{:});

Error in test_script (line 97)
REST(opts)

When I checked online, I found once this suggested solution. Any suggestions on rectification of this error?

Also, can you please let me know if the datasets used in your REST paper are publically available?

Thanks and Regards
