The first step to using the Open EEGLAB Portal is to create an NSG account [HERE](https://www.nsgportal.org/gest/reg.php) (or by clicking on "Register account" on the NSG home page).
After your account is approved by the NSG team (typically within 2 days), the second step is to enter your NSG user credentials [HERE](https://nsgdev.sdsc.edu:8443/portal2/login!input.action) (else select, "Access NSG portal" on the [NSG home page](http://www.nsgportal.org/)).

The figure below shows a scheme of function calls in _nsgportal_. In the plug-in there are two main sets, or layers, of functions designated by the prefix _pop__ and _nsg__. The _pop__ functions open a parameter entry window when called with fewer than the required arguments, else run directly without opening a window. The second class of nsgportal functions with prefix _nsg__ can be called directly from MATLAB command line or from other MATLAB scripts or functions. These functions perform lower-level processing than the pop_ functions. A plug-in function (_eegplugin_nsgportal_) manages the inclusion and appearance of an nsgportal item in the main EEGLAB window menu.

The second function will be the focus of this tutorial. The aim of the plug-in is to perform ICA decomposition via NSG using one of two implemented decomposition approaches, 'runica' or 'jader', that performs Infomax or JADE ICA decomposition, respectively. If called from the EEGLAB menu by manually selecting the EEGLAB GUI menu item specified in the *eegplugin_icansg* function (see figure below), the plug-in will use the current EEG dataset structure loaded into EEGLAB, and will pop up an option entry window asking which ICA method to use. The figure below shows the *eegplugin_icansg* menu item selected and the *pop_icansg* window popped up as a result.
The plug-in pop-function (*pop_icansp*)can also be called from the MATLAB command line; in this case, you may pass as input the EEG dataset structure you want to decompose as well as the decomposition method to apply to the data. The sample code below specifies both the EEG dataset structure to operate on and the ICA decomposition type to apply; it thus will perform ICA decomposition via NSG on the currently loaded (EEG structure) dataset (using *'runica'*) *without* popping up a parameter input window:

Start by login into the NSG portal. Once logged in, you may upload a **zipped file** containing 1) an EEGLAB script calling 2) one or more data files by name (they should be in or under the same folder as the script). Then click on the "Data" tab and select "Upload data", then upload a file containing your script and data.
You may download a 3.5-MB sample zip file (containing EEG data and a sample script [HERE](https://sccn.ucsd.edu/mediawiki/images/7/7c/Testingeeglabonnsg.zip). Below is its list of contents:
Now create a new NSG task. To do this, click on the "Task" tab and select, "Create new task." Click on, "Select input data" and select the zip file you have uploaded above. Click on "Select tool" and select "EEGLAB".
Then click on "Select parameters". Enter the name of your script. This script must be at the root (top) folder of your zip archive. You may also (optionally) change other NSG settings on this page.
Finally, press "Save parameters". This will bring you back to the previous screen. You may now press, "Save and Run Task" which will enter the task into the Comet queue. A warning is shown as in the image below. Simply click OK.
You may now download the task output, a zip file containing the results of your task. Output files (see listing below) include the Matlab log and error log for your task. If your script saved data files, they will be there. For example, if you use the zip file and script provided above, below (left) is what the unzipped output archive will contain. The figure below (right) is the .jpg image created by the test.m script. Saving output images in Matlab .fig format (instead of .jpg) will allow you to read them into Matlab (for further editing, etc.). Note: The numeric data plotted in a figure can be read from the .fig file structure as well. Alternatively, saving figures in Postscript (e.g., as .epsc) will allow you to edit them in Illustrator.

Note: To save needless transfer time and effort, the uploaded data file itself will not be returned with the output unless your script explicitly saves it under a new name. In future this will also allow you to temporarily store and reuse the uploaded data.
