[Eeglablist] multiple runs/parts of the same paradigm - when to concatenate

[Janosch Linkersdörfer]

Hi all,

I am writing a script to import EGI .mff data into eeglab and save them as .set files for further (pre)processing.

One of the paradigms is split into two runs. For another paradigm that should have been run in one go, for some of the participants there are two files, because the participants (children) had to go to the bathroom in between blocks.

In the script I look whether multiple files for one paradigm exist, and if so concatenate them using pop_mergeset.

I now wonder whether this is correct or whether I instead have to preprocess each file individually and later concatenate them before (or after) epoching.

It would be great if you could help me!

Thanks,

J
