  Nicoara, hi.

  
  

  Are you installing the GUI from the source code, as outlined here,

  
  

  https://github.com/OpenBCI/OpenBCI_Processing
  

  
  

  Users have occasionally had difficulty with some of the pre-built Downloads on this page,

  
  

  http://openbci.com/index.php/downloads
  

  
  

  So installing directly from source is usually the solution.

  Hello William,

  
  

  Thanks for the reference!

  
  

  Sorry for the late response. 

  After copying the instructions there 

  (I have folders C:\Users\nicoara\Documents\Processing\OpenBCI_GUI, C:\Users\nicoara\Documents\Processing\libraries\controlP5, C:\Users\nicoara\Documents\Processing\libraries\gwoptics)

  and pressing run on C:\Users\nicoara\Documents\Processing\OpenBCI_GUI\ControlPanel.pde, it throws the following errors in Processing:

  
  

  "

  No library found for ddf.minim.analysis

  No library found for ddf.minim.ugens

  No library found for controlP5

  No library found for ddf.minim.analysis

  Libraries must be installed in a folder named 'libraries' inside the 'sketchbook' folder.

  
  

  "

   

  I have not been able to figure out what the problem is.

  Do you know?

  
  

  Thank you,

  Hello wjcroft,

  Thank you for helping me, the second link fixed the error. 

  
  

  Unfortunately, I have a new error now. The window for openbci opens quickly then crashes. I have looked online for help, it seems to be an opengl problem. Also, it may be relevant that ControlP5 has an orange exclamation next to it in the libraries section of Processing, even when I update it at 2.2.6. The crast message is as follows:

  
  

  "Could not run the sketch

  Restarting the entire process again, somehow the error disappeared. For completion, I solved for ddf.minim.analysis by installing the library Minim from the Import Library. Thank you

  Most of the time you can fix this problem by uninstalling the Java runtime and then reinstalling it all over again.  If you have both 32- and 64-bit applications that need to use Java, then you’ll need to download and install both versions of the Java runtime. Hopefully, this will fix your problem. Sometimes this error can be caused by not having enough system memory allocated to the Java Virtual Machine – or not enough system memory. In this case try the following :

  
  

  Tap on Windows-Pause to open the System Control Panel applet. You can alternatively open the control panel manual to go there if you prefer it that way.

  Click on advanced system settings on the left.

  Select environmental variables here.

  Click on new under System Variables.

  Enter _JAVA_OPTIONS as the variable name.

  Enter -Xmx512M as the variable value.

  Click ok twice.

  
  

  This allows up to 512MB to be allocated to the Java virtual machine. You can experiment with different values, if required. That's it, your Java program should now be able to execute properly.

  
  

  For those interested, Java -Xmx/s is the configuration parameter that control the amount of memory Java uses.

  
  

  Xmx sets the maximum heap memory size

  Xms sets the minimum heap memory size
