The workshop in full swing.

Satellite Workshop Goals

  • To educate attendees in the fundamentals of Diffusion Tensor Imaging (DTI) data required to make informed decisions about how to analyze their own DTI data.
  • To provide tutorials on DTI data validation and management (including how to put your image data into NRRD format, an emerging standard endorsed by the NA-MIC and BIRN* communities).
  • To provide hands on tutorials in the use of NA-MIC DTI analysis tools.
  • To establish contact between NA-MIC Tookit experts (users and developers) and basic and clinical researchers in the global neuroimaging community.

Workshop Logistics

  • Enrollment is limited to approximately 45-50 attendees due to the highly interactive format of the workshop.
  • The material is targeted for an audience of graduate students, research fellows, junior faculty, research assistants and post-doctoral trainees from among the fields of clinical neuroscience (Psychiatry, Psychology, Neurology) as well as Radiology, and Computer Science.


  • To register, send an e-mail to Katie Mastrogiacomo (kmast at Please include your contact information including full spelling of your name, degree, current institution, preferred email address for communication, your educational background and training and your reason for attending. We would also appreciate it if you would indicate the characteristics of the computer you will be using for the workshop (OS, RAM, Processor).
  • A deposit is required to hold your place in the workshop. Please mail a check or money order for $50.00 US made out to "Brigham and Women's Hospital, NA-MIC project" to Katie Mastrogiacomo, Surgical Planning Laboratory, Department of Radiology, Brigham and Women's Hospital, Room L1-050, 75 Francis Street, Boston, MA 02115.
  • Your deposit will be returned to you at the Workshop. If you are unable to attend after registering and give us 48 hours advance notice, your deposit will be returned, otherwise you will forfit this earnest money.

This is hands-on training. All participants must come with their own computer and install our software and data. Windows XP, Linux or MacOS 10.4 computers are supported. A minimum of 1 GB of RAM (2 GB if possible) and a dedicated graphic accelerator with 64mb of on board graphic memory are recommended.

Please complete the following items prior to the workshop.

  • Software Installation: Please install the newest release of the Slicer program Slicer2.6 appropriate to Operating System of the computer you will be bringing to the workshop.

NOTE: Intel based Macs will be supported on an experimental basis. Mac users please be sure to install the X11 application (available from the Mac OS X install disks).

NOTE: Windows Vista is not supported at this time.

We will be happy to assist anybody who may encounter difficulties in the installation process. As first point of contact, send an email to the NAMIC-developers mailing list which will be closely monitored by NA-MIC Tookit experts. Because we will focus on how to use the application(s) during the workshop not on how to install it, please do the install before you arrive. Most people find that the installation can be completed without difficulties. If you need any hands on assistance after making attempts to complete this on your own with email support, please arrive early (8:00 AM).
