Я все еще новичок в Octave с некоторым опытом в Python, и мне было предложено сделать тест в приложении стимула, чтобы найти, есть ли ошибки в коде (не разработан мной) и попытаться их исправить и запустите приложение. Проблема в коде заключается в том, чтобы в то время открыть экран следующим образом (те, где я прокомментировал (%) - это то, что уже делали ранее, и те, что под комментариями - мое исправление), код большой с 825 строками:
%% Get subject name from the user
prompt = {'Enter Subject Number:','Enter Subject Name:','Enter Todays Date:','Left or Right:'};
dlgtitle = 'Information Input';
%dims = [1 50];
dims = [1 50;1 50;1 50;1 50];
opts = 'on';
answer = inputdlg(prompt,dlgtitle,dims);
%waitfor(answer);
waitfor(dims);
%% TO Excel
% Get the name of the file that the user wants to save.
%startingFolder = userpath;
startingFolder = 'C:\Users\Vtr\Downloads\Final-task-981203\Final-task-981203\Task-981203';
defaultFileName = fullfile(startingFolder, '*.xlsx');
[baseFileName, folder] = uiputfile(defaultFileName, 'Specify a filename ');
if baseFileName == 0
% User clicked the Cancel button.
return;
end
% Combine the folder and base file name into the full file name.
fullFileName = fullfile(folder, baseFileName);
%% LOAD text initial setting
%% Create 1st screen : (Loading and Wait)text screen
% Open an on screen window - purple screen
[window, windowRect] = PsychImaging('OpenWindow', screenNumber, [0.5 0.5 1]);
% Set up alpha-blending for smooth (anti-aliased) lines
Screen('BlendFunction', window, 'GL_SRC_ALPHA', 'GL_ONE_MINUS_SRC_ALPHA');
После этого в первой части создается форма для вставки темы №, имени субъекта, сегодняшней даты и слева или справа, а после этого указывается имя файла. Сделав эти две части, он выглядит как фиолетовый экран с непрерывным вращением курсора мыши, и если я пытаюсь щелкнуть мышью, появляется окно с сообщением об ошибке «octave- gui .exe перестал работать». Я уже пытался запустить этот код на моей Virtualbox-VM (Ubuntu 16.04 LTS), во-первых, он уведомляет о том, что мой экран тестируется и калибруется, а после этого на терминале появляется другой экран ошибки:

----- ! PTB - ERROR: SYNCHRONIZATION FAILURE ! -----
One or more internal checks (see Warnings above) indicate that synchronization
of Psychtoolbox to the vertical retrace (VBL) is not working on your setup.
This will seriously impair proper stimulus presentation and stimulus presentation timing!
Please read 'help SyncTrouble' for information about how to solve or work-around the problem.
You can force Psychtoolbox to continue, despite the severe problems, by adding the command
Screen('Preference', 'SkipSyncTests', 1); at the top of your script, if you really know what you are doing.
error: Screen: See error message printed above.

Я хотел бы знать, заключается ли проблема в конфигурациях моего компьютера, которые не поддерживают ресурсы Psychtoolbox, или в любой конфигурации, которую мне нужно изменить.
