Describe the bug
When reading an EEGLAB file with mne.io.read_raw_eeglab(), the events information seems oversimplified.
In EEGLAB, the set file event structure contains the following:
>> EEG_set.event
ans =
1×2670 struct array with fields:
description
begintime
classid
code
duration
label
relativebegintime
sourcedevice
name
tracktype
latency
type
mffkeys
mffkey_gidx
mffkeysbackup
mffkey_age_
mffkey_exp_
mffkey_hand
mffkey_sex_
mffkey_subj
mffkey_cel
mffkey_obs
mffkey_spc
mffkey_pos
mffkey_argu
mffkey_rsp
mffkey_eval
mffkey_rtim
mffkey_trl
mffkey_blk1
However, after reading the SET file with mne.io.read_raw_eeglab(), I can only see annotations with onset, duration, description and orig_time information:
>>> raw.annotations
<Annotations | 2670 segments: CELL (4), DIN2 (666), SESS (1), TRSP (666), ...>
>>> raw.annotations[0]
OrderedDict([('onset', 0.255321), ('duration', 2.0), ('description', 'SESS'), ('orig_time', None)])
>>>
>>> raw.annotations[1]
OrderedDict([('onset', 0.46732), ('duration', 2.0), ('description', 'CELL'), ('orig_time', None)])
And when I export the raw structure into a new SET file, the event structure of the file is as follows:
>> EEG_new_set.event
ans =
1×2670 struct array with fields:
type
latency
duration
Is there a way to keep the same events structure as the original SET file?
Steps to reproduce
raw = mne.io.read_raw_eeglab(input_fname=<FILE PATH>, preload=False, verbose=True)
mne.export.export_raw(
fname=<NEW FILE PATH>,
raw=raw,
fmt='eeglab',
overwrite=True
)
