Hi,
I'm having trouble with a script when trying to use DrawTexture.
I keep getting the error message below:
displaycommand = Screen('DrawTexture',w,imagetex(i),[],pRect{i});
Error in function DrawTexture: Invalid Window (or Texture) Index provided: It doesn't correspond to an open window or texture.
Did you close it accidentally via Screen('Close') or Screen('CloseAll') ?
??? Error using ==> Screen
Usage:
Screen('DrawTexture', windowPointer, texturePointer [,sourceRect] [,destinationRect] [,rotationAngle] [,
filterMode] [, globalAlpha] [, modulateColor] [, textureShader] [, specialFlags] [, auxParameters]);
Error in ==> MSS_test at 654
eval(displaycommand);
Nowhere in the script is there a Screen('Close').
Here is the script I think the error message is referring to :
% setup text to be displayed (as written, will center text and
% wrap at default_wrap pixels)
displaycommand = sprintf('DrawFormattedText_new(w,stFile{i},''center'', ''center'',black, default_wrap,hshift(i),vshift(i));');
elseif st(i) == 's' %primary stimulus is sound
eval(bg_display); %present the background file while sound is playing
Screen('Flip',w);
t1 = GetSecs;
% Open the default audio device [], with default mode [] (==Only playback),
% and a required latencyclass of zero 0 == no low-latency mode, as well as
% a frequency of stSoundList{i,2} = fs, and nrchannels sound channels.
% This returns a handle to the audio device:
pahandle = PsychPortAudio('Open', [], [], 1, stSoundList{i,2},nrchannels);
% Fill the audio playback buffer with the audio data 'stSoundList{i,1} = x from above':
PsychPortAudio('FillBuffer', pahandle, stSoundList{i,1}');
t2 = GetSecs;
if DEBUG
fprintf( 'It took %f seconds to open PsychPortAudio and fill the buffer in iteration %d\n',t2-t1,i);
end
% Start audio playback for 'repetitions' repetitions of the sound data,
% start it immediately (0) and wait for the playback to start, return onset
% timestamp.
t1 = PsychPortAudio('Start', pahandle, rep(i), 0, 1);
onset(i) = t1 - experiment_start_time; %sound onset
sound_closed = 0;
displaycommand = bg_display; %For sound, foreground and background images are same
elseif st(i) == 'p' %primary stimulus is a picture
displaycommand = sprintf('Screen(''DrawTexture'',w,imagetex(i),[],pRect{i});');
end; % if st(i)
if DEBUG
fprintf('\ni= %d,\nst(i) = %c\n',i, st(i));
fprintf('displaycommand = %s\n\n',displaycommand);
end;
%%%%%%%%%%%%%%%%%%%%%%%
%Put stimuli on screen
%%%%%%%%%%%%%%%%%%%%%%%
t1 = GetSecs;
eval(displaycommand);
[vbltime,start_time]=Screen('Flip',w);
t2 = GetSecs;
fprintf('We needed %f seconds to Draw texture %d.\n',t2-t1,i)
Also, I am using a Windows 7 machine with Matlab 2009b in 32-bit and Psychtoolbox 3.
Any help is appreciated.
