UI issue with P300 Speller

Post by openvibeexplorer »

Hello,

I have downloaded the code for OpenVibe 3.1 and built it. I am facing one User Interface (UI) issue in the training scenario. I am elaborating the issue along with the screenshots below.

Step 1 - When I open the list of classifiers for the first time, it appears as follows. (The default classifier is LDA)

Step 2 - After which when I change the classifier to SVM, UI appears like below.

Step 3 - Then when I change the classifier back to LDA, the UI appears with less options.

Why am I facing this issue? I am using Windows 10 with Visual Studio 13 Express Edition installed on my machine.

Hi,
It's a bug with the update of options we must investigate. Thank you for your report. Actually the only thing I can propose is to copy the basic box with LDA classifier to have option. (An other boring solution is to install (with setup an old version 2.2.0 for example) setting your box next open in 3.1 your scenario to have the other improve and your own modification.
