A new place for this toolbox
|
| |
Dear all:
I have created a new website for this toolbox and here is the link:
[link]
And now you can download the toolbox from this website.

The downloading file does not exist
|

Hi, I tried to download the toolbox file on the homepage of this
group. But it seems the link is bad that it points to a non-existing
file. Can someone check this for me? Thank.

how to identify hubs?
|
| |
Hello,
I was wondering what the best way was to identify the sites (be it EEG
or FMRI) that are 'best connected'. That is, I have a connected
matrix A in which I set the diagonals to zero. I then compare:
(1) degrees_und(A)
to
(2) degrees_und(randmio_connected( A,100))
and only retain the sites where (1) is greater than (2). Is this the... more »

help interpreting coherence /lambda_Coh
|
| |
Hi all I've just performed a coherence measure between two EEG time series. I get the following lambda_Coh (375 points, which corresponds to the time points I have in each epoch). However, I don't know how to interpret this. As explained in the paper, those should be the frequencies that the coherence is calculated for. If so, why are they... more »

help with analysis - EEG data
|
| |
Hi all, I need some help with my analysis as I am just now starting to play around with this toolbox. I have EEG data, with 60 channels. In my experiment I have 2 types of events that I want to compare and therefore see whether there are any differences in responses. Within the time series, there are 39 epochs... more »

Matlab Toolbox: EEG data?
|
| |
Hi all, I'm a new member and I've just finished reading the paper related to this toolbox. If I understand correctly, this toolbox can only be used for fMRI data, and not EEG. If so, would you suggest making my own scripts in matlab or adjusting the ones from the toolbox in order to be used for EEG data? (eg the correlation functions).... more »

Hi!
Thank you for your nice toolbox for FC.
I'm a beginner in terms of FC.
Just I type some command like below in Matlab
I encountered errors.
Please let me know what I should miss it.
Thanks,

Appropriate preprocessing?
|
| |
Hello,
I am starting to use your toolbox (specifically the mutualinf
function) to develop a connectivity matrix for graph theoretic
analysis. I am curious as to exactly what preprocessing parameters I
ought to be using (most of my neuroimaging experience is with meg/
eeg). I have images realigned and normalized in spm. I thought I... more »
