Problems defining trials

[ghost]

Hi all. I am trying to make cardiac and respiratory regressors using the PhysIO toolbox in SPM. I have one .EEG file, including my respiratory and cardiac measures. I also have one .vhdr and .mkr file. When I run the code, I get the following error, indicating a problem with reading in the events. How can I change event_type or FT_DEFINETRIAL?

Dear Evelyne,

My apologies for the delay in responding, conference season and now summer is upon us...

I presume this is BrainProducts data? We are relying on Fieldtrip ft_* functions here and they might have changed since the implementation of that code. I am also no EEG analysis expert, so it would be great to get a better idea of the data.

Therefore, would you be able to share you SPM batch file and an example dataset, so that I can investigate further?

Thank you and all the best,
Lars

And I just realized that the BrainProducts reader might not be functional at the moment, please see this issue:

#225

As I stated there, it would be great to have some example data to implement unit and integration tests and make it work properly again. Please let me know if you are interested in pursuing this with me.
