[Mrtrix-discussion] commands not found

[Donald Tournier]

Hi Rakesh,

Looks like the executables are not in your path. Unless you've explicitly
set the PATH environment variable, neither of the folders you used would be
in the path by default. What does "echo $PATH" report? Are either of these
folders in the list? If not, that's the problem. I assume you didn't use
the "./build install" feature? If you did, then there's a different problem
and I'd need more information to figure it out, ideally a copy/paste of
your terminal session showing all the commands you typed and their output.

For Linux installs (and probably MacOSX too), I'd strongly recommend you
use the new "./build install" feature, as per the
documentation<http://www.brain.org.au/software/mrtrix/install/unix.html#install>.
By default, it will install all the executables and dynamic library into
/opt/mrtrix, and create symbolic links pointing to them in /usr/bin/ (and
/usr/lib/ for the shared library). This really should work on any
reasonably configured Unix systems. Basically, once you've successfully
built the executables (i.e. after "./build" completes without errors), then
simply type:

$ sudo ./build install

By the way, /bin really should be for system-related/superuser executables,
you shouldn't be installing user applications in there. If you really need
to, you should be using /usr/bin for user applications - /bin won't
normally be in the path for normal user accounts anyway.

Hope that fixes it.
Cheers,

Donald.
