Dear MEG developers,
I am encountering a problematic situation while saving epochs. I would like to take EEGLAB preprocessed EEG data from . set format conversion to .fif format , but it fails to save with this RuntimeWarning message:
C:\Users\SCEL.spyder-py3\temp.py:19: RuntimeWarning: This filename (26 post_ica_1.fif) does not conform to MNE naming conventions. All epochs files should end with -epo.fif, -epo.fif.gz, _epo.fif or _epo.fif.gz
data.save(subjects+’ post_ica_1.fif’,overwrite=True)
How can I solve this issue?
I need some help. Thanks!
Best,
Dan

for subjects in allsub:
    data_path='C:\\wangdan\\study 2\\EC_ICA\\'+subjects+' post_ica_1.set'
    data=mne.io.read_epochs_eeglab(data_path)
    data_path_save = 'C:\\wangdan\\study 2\\EC_ICA\\'+subjects+' post_ica_1.fif'
    data.save(subjects+' post_ica_1.fif',overwrite=True)

hi Dan

it’s not an error but just a warning.

to avoid this warning use:

post_ica_1-epo.fif

for the filename
