Choose or Convert Event-Marker Formats

Supported formats

Step 4 and EyeSort → Modify Event Code Format support:

• Numeric: CCRRLL, appropriate for ERPLAB/BINLISTER.
• Condition and label description: bdf_full_description.
• Description plus fixated word: appends current_word_text.
• Description plus word identifier: appends the raw current_word boundary key, typically a MATLAB-safe value such as x4_2.
• Region text content: displays the full current-region text.
• Original: restores original_type when available.

Fallbacks use the canonical numeric code when readable metadata is unavailable.

Canonical identity is preserved

Conversion rewrites only EEG.event.type on labeled events. It never changes eyesort_full_code. The first pre-EyeSort type is retained in original_type, making the display conversion reversible when that field exists.

EEG = convert_event_codes(EEG, 'description_word');
EEG = convert_event_codes(EEG, 'numeric');

Valid API values are numeric, description, description_word, description_index, region_content, and original.

Downstream choice

Use readable types for inspection or models that accept strings. Before BINLISTER, convert to numeric even though BDF generation itself reads eyesort_full_code.

In GUI batch mode, conversion finds *_processed.set files in the remembered output directory and saves each converted dataset in place. Retain a reproducible record of the selected format.
