 The motivation for separating the reading into header/​event/​data is (among others) inspired by the CTF and by the BrainVision data formats. Based on the header, you want to decide how to approach reading the data, i.e. read everything for an average ERP, read an epoch for trial-based data, read a segment for continuous data. Based on the events (triggers and such), you want to decide which segments of data to read, i.e. read a pre/​post-stimulus data segment around each trigger. These decisions are part of the FieldTrip/​SPM/​EEGLAB/​enduser code. The motivation for separating the reading into header/​event/​data is (among others) inspired by the CTF and by the BrainVision data formats.
