Re: Functional Connectivity algorithms
Hello, That is good to hear! Yes I have created a repository with the new algorithm files (https://github.com/stickp1/fc_openvibe). The code is commented, although the great majority of code is common across different algorithms. I don't think I have any documentation, how should I go about it? You ...

Re: Functional Connectivity algorithms
Hello again! On part of my work for the Master's thesis, I adapted the existing functional connectivity algorithms to provide more stable measures with regards to volume conduction, common reference, etc. I have crudely implemented: -> Imaginary Part of Coherency (Nolte et al, 2004) - two approaches...

Re: Configuration files
Hello, Is this still an issue for Openvibe 2.2.0? Because when I try to call the acquisition server from the command line using the --config switch for a file I created (base on acquisition-server-defaults.conf), it shows "Adding kernel configuration file [path to my file]" but still the configurati...

Re: Functional Connectivity algorithms
Yes I tested it on a very simple example with 2 channels, each with a sine wave, and a different phase shift between them for each trial. With the current implementation, the value for Magnitude Squared Coherence starts at 1 for a phase shift of 0º and as the shift increases to 90º the Magnitude Squ...

Re: Functional Connectivity algorithms
Thank you for your information! I have a note/question to make on the Magnitude Squared Coherence algorithm. I do not know if this is the right place for it, but I rather make all my contacts regarding the functional connectivity algorithms in a single place! In the definition of the Magnitude Squar...

Functional Connectivity algorithms
Hello, I have recently started using OpenVibe and plan on developing one or more connectivity algorithms for the connectivity measure box, since with the current ones volume conduction effects might be very large (I'm thinking in the lines of Imaginary Part of Coherency, Granger Causality...). Besid...
