[Eeglablist] LIMO Errors Importing Data

[Delorme, Arnaud]

We are working actively with Cyril Pernet on LIMO but what we use is the development version of LIMO. This is the version of LIMO most compatible with EEGLAB 2019.0 and 2019.1. I recommend you use this version. Simply clone LIMO below and switch to the development branch,

https://github.com/LIMO-EEG-Toolbox/limo_tools

Also, we are redoing the LIMO tutorial.

Best wishes,

Arno

>> Dear all,
>> I’ve been trying to use the LIMO toolbox for my data, but I can’t get it to work, not even with the tutorial data provided. I am not sure if these are bugs or if it is a compatibility problem. I tried different EEGLAB versions and settings, and it turns out, that the single trial data for the time-frequency analysis cannot be loaded, as it seems to be formatted inappropriately (see below). I created them with the LimoTools option and don't know how to proceed. It would be great if you could provide me your thoughts on how to solve this, as I really want to use this toolbox with my own data!
