The structure of a BIDS path

Assume the following BIDS path:

/storage/project-A/sub-01/ses-test/eeg/sub-01_ses-test_task-visual_eeg.vhdr

This path encodes for a number of different information on the recording.

(BIDS) Root

/storage/project-A/sub-01/ses-test/eeg/sub-01_ses-test_task-visual_eeg.vhdr

Data Type

/storage/project-A/sub-01/ses-test/eeg/sub-01_ses-test_task-visual_eeg.vhdr

Basename

/storage/project-A/sub-01/ses-test/eeg/sub-01_ses-test_task-visual_eeg.vhdr

Suffix

/storage/project-A/sub-01/ses-test/eeg/sub-01_ses-test_task-visual_eeg.vhdr

Extension

/storage/project-A/sub-01/ses-test/eeg/sub-01_ses-test_task-visual_eeg .vhdr

Note that in the current MNE-BIDS implementation, the extension contains the leading period.
