On Windows XP, run the installer file TrackVis_setup.exe and follow the instructions step by step.
On Mac OSX, open the disk image file TrackVis.img and copy the TrackVis application package
in to your Applications folder.
On Linux, just uncompress and copy the trackvis file to your bin or any other directory you would prefer.
After installation, just excute ~/your/bin/trackvis to run TrackVis and
~/your/bin/dtk to run Diffusion Toolkit (DTK).
Note for Linux users: it is strongly recommended to put trackvis executible in the same directory as Diffusion Toolkit
executibles (dtk, etc.). It would allow DTK to
launch TrackVis program conveniently.
