Need a parameter file which can be controlled by mouse!!!

[amityadav]

Hello every1 I am new to this forum, i have question i am working on web browser which will be controlled by brain signals .To test it i am using RJB_Randomnumber.prm which is generating a random number but we want to control this random number , so can any one tell me is there a parameter file which i can use , whcih will generate random number but which we wil be able to control by muse , like if we move mouse up the number should increase and if we move down the mouse the number should decrease.

Also, if there is any such file then do i need to change any thing in the RJB cODE or just need to include the parm file.

Thanks

Hi,

The BCI2000 installation (bci2000setup.exe) comes with such a parameter file for the RJB task. Just install it in a separate directory and look at the parms directory.

I would really appreciate if you can tell me the name of the file also.

Hi,

It's RJB_RandomNumber.prm.

Hi gerv

i appreciate ur help and prompt reply but in my current application i am already using this parameter file but is not able to control the random numbers by mouse. Do i need to change any settings or do i need to make an changes in the RJB code.

Just to give u an idea, whats happening is that we have a web browser which have control panel and we have one dimensional navigation . Now in order to traverse thru the various buttons in the control panel, we are using this RJB random number file and using this number to build our logic of using on this random number to either move thru the buttons of control panel or fire the event of any button. bUT SINCE WE DONT HAVE ANY Control over this random numbers we are not able to do our proper testing , that's why we want a file whose number generation can be controlled by mouse.
I hope this must have given u some idea of what we are into

i would really appreciate ur help if u can tell what can be the possible solution.

Thanks

Hi,

This is very strange. It works for me. We must have different versions of the file. Just to make sure, here is what I use:

Hi gerv,

for some reason this is not working for me, i tried ur version of file by copying and pasting that and then tried to us that parameter file but still not able to control the random numbers by mouse.

Can u tell what can be the reason , do i need to chenge anything in the code.

Thanks and really appreciate ur help
Amit

Hi,

I don't really understand this. Why don't you try this: Load the parameter file, and then go to Source and set the parameter ModulateAmplitude to 1. If you do that and start the system, you should see sine waves on all channels that get larger or smaller if you move the mouse up and down.
