[FieldTrip] Error with mutual information

[Xavier Vrijdag]

HI Gian,

I am using the mutual information analysis provided by the IBTB toolbox in fieldtrip.

You can check in the fieldtrip/external/ folder if the IBTB folder exists. In my fieldtrip downloads the IBTB toolbox is available. Otherwise you can download it from the fieldtrip github: https://github.com/fieldtrip/fieldtrip/tree/master/external/ibtb

In general, I can recommend you to use the ft_connectivityanalysis function instead of the lower-level function ft_connectivity_mutualinformation.

Regards,

Xavier

Subject: [FieldTrip] Error with mutual information

Hi everyone, I'm trying to run mutual information as a measure of functional connectivity. When I run the command  ft_connectivity_mutualinformation I receive the following message

Error using ft_hastoolbox (line 450)
the IBTB toolbox is not installed, see http://www.ibtb.org<http://www.ibtb.org>

Error in ft_connectivity_mutualinformation (line 48)
ft_hastoolbox('ibtb', 1);

The web site reported in the error line is not active anymore. Therefore I downloaded the ibtb toolbox from the supplementary material of the paper Magri et al. 2009, at the following link
https://link.springer.com/article/10.1186/1471-2202-10-81<https://link.springer.com/article/10.1186/1471-2202-10-81>

I installed as usual the toolbox, I decompressed it and I added it to the matlab path as suggested by the installation file. However I continue to receive the same error message.
Do you have any suggestions?
Thanks
