[FieldTrip] A question on ft_timelockanalysis

[Schoffelen, J.M. (Jan Mathijs)]

I don’t know about the specific way of importing the data into matlab, but the call to ft_redefinetrial (on line 31 of your script) requires the second input argument to be a data structure that fieldtrip ‘understands’. If it’s not compatible then FieldTrip does not know what to do with it. I suggest that you check the documentation on www.fieldtriptoolbox.org<http://www.fieldtriptoolbox.org> to get started (e.g. look in the getting started section https://www.fieldtriptoolbox.org/getting_started/brainvision/ or https://www.fieldtriptoolbox.org/reference/ft_datatype_raw/

Note, also, that the second input argument into ft_redefinetrial should never be a name of a file, but rather the contents of the file. Alternatively, you could specify cfg.inputfile = dataSet, and omit the second argument in the function call

Best wishes,
Jan-Mathijs

Hello, I'm Jaewon.
I'm trying cluster-based permutation test with my EEG data imported from BrainVision analyzer to Matlab.
I imported my data this way : https://www.youtube.com/watch?v=wyLg40dLwJo<https://urldefense.com/v3/__https://www.youtube.com/watch?v=wyLg40dLwJo__;!!HJOPV4FYYWzcc1jazlU!-qJ8l5xgUbGkuWdckQM2318bRKwuTpnxkmqXHfiu_E4qKGB7TtOzaSSfdLYx3ycsi0Su36IikOzEPLmpJr9Z0Vb8AvzGkT01jOTtFA$>
(I used BVA2Matlab function introduced in the video and I know that BVA2Matlab results in the output form of ft_preprocessing.)

However, I encountered the following errors:
[X]

( I gathered data of the first condition in a folder named 'HH'.)
Why did this happen?

All the best,

Jaewon
