[Eeglablist] Efficiently removing period of trials in complete study

[Morteza Ansarinia]

Hi Luuk,

You can write MATLAB scripts. Here is the tutorial: https://sccn.ucsd.edu/wiki/Chapter_02:_Writing_EEGLAB_Scripts <https://sccn.ucsd.edu/wiki/Chapter_02:_Writing_EEGLAB_Scripts>

I used to run all the processings manually by GUI only for a single subject, and then export what I did as a script using “File > History scripts > Save dataset history script”. You can then modify the script and run it on all datasets...

To extract epochs and remove baseline you can use something like this:

EEG = pop_epoch(EEG, {‘cond1’ 'cond2’}, [-1  2.5], 'epochinfo', 'yes');
EEG = eeg_checkset(EEG);
EEG = pop_rmbase(EEG, [-1000 0]);
EEG = eeg_checkset(EEG);

Best,
Morteza

> I have created a study of multiple datasets and each dataset consists of x number of trials, each trial lasts 3.5s (1s pre-stimulus and 2.5 post-stimulus). Now is there an easy way to remove the first second of each trial in all datasets in the whole study?
