rec2track_qt

C++ tool for stimuli presentation and behavioural recording Used in conjunction with the Meyer lab 2p microscope to produce visual stimulation patterns synchronized to the 2p brain images.

 // Important note on projection screen: //////////////////////////////////////////
    // The second screen needs to be positioned as

    //       |^^^^^^^^^||^^^|
    //       |         || 2 |

    // The projection screen size must be 800x600 (4:3).
    // To avoid the appearance of the topbar use GNOME Classic as desktop environment
    // 

Remember to Switch projector to HDMI input, so it becomes the Desktop's 2nd screen.

The opt directory needs be found one up from the folder where the binary is being executed, and needs to contain the following input files :

• StimLibFolder.txt : the folder where the stimulus barrage binaries are to be saved and loaded from.

Output files:

• time_epoches.txt : The main output file of interest is the
• settings.txt:

Behavioural recording and Tracking

During behavioural recording a display of the realtime video is shown. Going through the code i Found the following keys give the user some control over options:

while(c!='q'){
       if(c=='f') ind+=speed;
        if(c=='t') ind+=40;
        if(c=='b') ind=max(0,ind-speed);
        if(c=='h') hide_trace=!hide_trace;
