| Your life as a neuroimager will be much easier if you have a good grasp on Linux (Unix) and Matlab.

The short introduction to [http://imaging.mrc-cbu.cam.ac.uk/imaging/LearningMatlab Matlab for psychologists] from the University of York is also useful. '''Linux (Unix): ''' This is a systemtic and well-illustrated [http://www.ee.surrey.ac.uk/Teaching/Unix/ introduction to linux]. '''Other sofware:''' Most software packages will offer tutorials and demos. They will familiarise you with basic analysis principles, visualisation options, and give you an overview of what's available to you. It makes sense to do the tutorials of software packages even if you are not planning to use them routinely. For example, MNE includes an example data set (tutorial in the manual), and there is a [http://imaging.mrc-cbu.cam.ac.uk/meg/SpmDemo demo analysis pipeline for SPM5]. All commercial software packages (CURRY, BESA, ASA, EMSE...) offer tutorials. And finally one last piece of advice: Talk to people! Ask questions! Try things out! And never give up... |
