[Eeglablist] Creating and Saving Difference Waves

[Cedric Cannard]

Hi Naomi,

The differences between conditions is done at the STUDY level. You just need to process your files one by one, save them as .set files, and then create a STUDY, edit the design, and run statistics to see the differences between your conditions.

See the tutorial here: https://urldefense.com/v3/__https://eeglab.org/tutorials/10_Group_analysis/study_creation.html__;!!Mih3wA!DGYuXvVPv2X6M9VXsLHtfVMCjR7CIooh8hzfrHa_IyZvpBBmY0-CMfgZMrXr31mApvmC7PM3tSoOXhZZhHC53ScRwg$
