Dview is now installed on MGH NMR Center computers, and the version is kept concurrent with that on the MIT Athena systems used for the HST-583 course. This document describes how to set up and run the software at the NMR Center. Note that most of the Linux workstations available at the NMR Center are considerably faster than the Athena workstations at MIT.

Requirements

• a PC running Linux or Windows or a Sun computer
  (performance on PC's has been much faster)
• access to the network file system at the NMR Center

Initial setup

These instructions assume that you do not have a ~/matlab directory and/or startup.m file. If you do, proceed as indicated but instead of creating the files and directories described below, all you need to do is add the lines of text given at the end of the instructions to your ~/matlab/startup.m file. This file is automatically read by matlab on startup and can be used to set paths (for finding commands) and otherwise set up your working environment.

This initial setup should only need to be carried out once.

1. make sure you are in your home directory:

     cd
   

2. create (or go to) your matlab directory:

     mkdir matlab
   
   or, if you already have this directory:
   
     cd matlab
   

3. create (or open) your startup.m file using a text editor like emacs or gedit:
   (gedit may seem more user-friendly to beginners - Linux only though)

     emacs startup.m
   or
     gedit startup.m
   

4. add the following lines to the end of the startup.m file

   path(path,'/usr/devsw/packages/SigLab/current')
   path(path,'/usr/devsw/packages/SigLab/emma/R12')
   

Running Dview

1. change to the directory containing the lab datasets:
   (or whatever datasets you want to look at)

     cd /usr/devsw/packages/SigLab/data/
   

2. start Matlab version 6.1:

     matlab6.1
   

3. run Dview from the matlab shell:

     >> Dview
   

Online tutorials for the labs (acquisition and physiology) are available under the Help menu visible at the top of the Dview window.
