Download link:

     WINDOWS 
     
     *You may need to install Microsoft redistributable package here to run DSI Studio if it complains missing some dll files.
     Please download the zip file dsi_studio_64.zip from one of the following links and unzip it to a folder. Click on the DSI Studio program icon to run it. 
     Google Drive
     Box
     One Drive

     MAC OS X 
     Please download dsi_studio_64.dmg from one of the following links and open it. You may need to enable the permission to run a 3-party app (see instruction).


     *IMPORTANT* DSI Studio will crash on Mac OS 10.12 Sierra due to incompatibility problems in the OpenGL functions (no solution identified yet). Please upgrade Mac OS to the most recent version, or you may need to use an older version of DSI Studio before 2019 (link to the previous versions provided in the bottom). I am sorry for the hassle.

Source Code:

Consistency:

     DSI Studio has a very high turning rate, and occasionally the computation outcome may be different between versions. I would recommend users keep a local copy of DSI Studio for each research project and only update DSI Studio if a new project is initiated.

Hardware recommendation:

     You can use regular laptops or workstations to run DSI Studio. To achieve the best performance, I would recommend a computer with multi-core CPU (e.g. http://store.hp.com/us/en/mdp/business-solutions/z840-workstation). A minimum memory of 2GB is needed. To handle a large number of tracks or image volumes, DSI Studio will need 32GB of memory or more. 

     GPU computation is not yet supported in DSI Studio. 


Recent Updates:

     02/28/2019 DSI Studio now supports automatic fiber tracking. 

     06/11/2018 DSI Studio now is able to show graph presentation. Check out: http://dsi-studio.labsolver.org/Manual/tract-specific-analysis#TOC-Connectivity-matrix-and-graph-analysis

     06/08/2018 New network measures implemented: Rich club with level=5, 10, 15, 20

     05/07/2018 Calculate helix angle for cardiac DTI
   
     05/02/2018 QSDR reconstructed FIB will also output DTI measures (FA, ADC, MD)

     04/11/2018 DIS Studio can do distortion correction similar to TOPUP but will use the entire DWI. It will need full AP or PA (LR or RL also works). Check out: http://dsi-studio.labsolver.org/Manual/Parse-DICOM#TOC-Optional:-Correction-for-susceptibility-artifact

     04/04/2018 User can use a simple "parameter ID" to run command line fiber tracking. There is no need to assign each of the tracking parameters.

     03/05/2018 Connectometry can now be applied to animal scans.

     03/01/2018 QSDR supports any external templates. It can be applied to animal scans.
