 ====================
 
-EEGLAB supports reading most iEEG data formats (EDF, MEF3) through native code 
-or plugins. The BIDS-matlab-tools EEGLAB plugin
-also support importing BIDS formatted MEG data. You may install plugins from the EEGLAB plugin manager (menu item <span style="color: brown">File > Manage EEGLAB extensions</span>).

+## Importing data
+
+For example, after installing the MEF3 and BIDS-Matlab-tools plugins, you may import the 
 [ds003708 BIDS dataset](https://nemar.org/dataexplorer/detail?dataset_id=ds003708&processed=0). 
 First, download the data. Second, use menu item <span style="color: brown">File > BIDS Tools > Import BIDS folder to STUDY</span>. 
 Leave all defaults and press OK (you may also select the column of interest for event types). Alternatively, use
 menu item <span style="color: brown">File > Import data > Using EEGLAB functions and plugins > Import MEF3 folder</span> to import the <i>mefd</i> 
 folder located in the <i>ds003708/sub-01/ses-ieeg01/ieeg/</i> folder of the BIDS dataset.
 
-When importing with BIDS, the advantage is that, along with the data, you will likely have access the iEEG electrode locations and relevant events. We show below the raw sEEG data for the unique subject in BIDS dataset <i>ds003708</i>.

-Even if you are not planning to use EEGLAB to process iEEG data, importing your iEEG data into EEGLAB and resaving it into an EEGLAB dataset may be useful to process it in other software.

+## Importing spike information
+
+EEGLAB allows importing spikes as events when using the NWB (Neurodata Without Border). Below, we show an example using the file [sub-01_ses-20140828T132700_ecephys+image.nwb](https://api.dandiarchive.org/api/assets/94ba06fc-c870-4698-9c31-f403ee733887/download/) of this [DandiSet](https://dandiarchive.org/dandiset/000576/). After downloading the file, and after installing the NWB-io EEGLAB plugins (menu item <span style="color: brown">File > EEGLAB extensions</span> then install the NWB-io plugin). After installing the plugin, import the file above in EEGLAB using menu item <span style="color: brown">File > Import data > Using EEGLAB functions and plugins > From NWB file</span>.
