Installation

Brainstorm must be installed prior to installing nirstorm.

The script nst_install.m takes care of copying or linking processes and functions into the brainstorm user folder.

Parts of the nirstorm plugin may already be shipped with the lastest brainstorm version and are available in the process selection menu in the "NIRS" submenu (modified bear lambert law and bad channel tagging). The current installation will override them.

Run brainstorm before installing nirstorm. All commands indicated below must be run in the nirstorm folder where the archive was uncrompressed.

Copy installation (windows, linux)

To copy all processes and functions into the brainstorm user folder, run under matlab:

>> nst_install('copy');

When updates are downloaded, this installation command must be run again for changes to take effect.

Linked installation (linux only)

To create symbolic links of all processes and functions into the brainstorm user folder, run under matlab:

>> nst_install('link');

When updates are downloaded, this installation command has to be run again only if there are new files.

Usage

The main documentation is in the form tutorials available on the nirstorm github project wiki.
