 [BIDS specification](https://bids-specification.readthedocs.io/en/stable/).
 
-BIDS currently supports MRI, MEG, EEG, iEEG, behavioral, and physiological data
-and more modalities will be added.
+BIDS currently supports the following data modalities with more to come in the future:

 1.  **Data type** - a functional group of different types of data.
-    BIDS defines eight data types:
-    `func` (task based and resting state functional MRI),
-    `dwi` (diffusion weighted imaging),
-    `fmap` (field inhomogeneity mapping data such as field maps),
-    `anat` (structural imaging such as T1, T2, PD, and so on),
-    `meg` (magnetoencephalography),
-    `eeg` (electroencephalography),
-    `ieeg` (intracranial electroencephalography),
-    `beh` (behavioral).

     Data files are contained in a directory named for the data type.
     In raw datasets, the data type directory is nested inside subject and
     (optionally) session directories.
