Screen('CloseAll') will auto-close them. PTB-INFO: This may be fine for studies where you only use a few textures or windows, but a large number of open PTB-INFO: textures or offscreen windows can be an indication that you forgot to dispose no longer needed items PTB-INFO: via a proper call to Screen('Close', [windowOrTextureIndex]); , e.g., at the end of each trial. These PTB-INFO: stale objects linger around and can consume significant memory ressources, causing degraded performance, PTB-INFO: timing trouble (if the system has to resort to disk paging) and ultimately out of memory conditions or PTB-INFO: crashes. Please check your code. (Screen('Close') is a quick way to release all textures and offscreen windows) INFO: PTB's Screen('Flip', 10) command seems to have missed the requested stimulus presentation deadline INFO: a total of 54 times out of a total of 1285 flips during this session. INFO: This number is fairly accurate (and indicative of real timing problems in your own code or your system) INFO: if you provided requested stimulus onset times with the 'when' argument of Screen('Flip', window [, when]); INFO: If you called Screen('Flip', window); without the 'when' argument, this count is more of a ''mild'' indicator INFO: of timing behaviour than a hard reliable measurement. Large numbers may indicate problems and should at least INFO: deserve your closer attention. Cfe.
