[Mrtrix-discussion] error installing MRtrix on Centos

[Donald Tournier]

Hi Keith,

We have the same issue on some of our servers running CentOS. It is
unfortunately a totally outdated distribution - even the latest release does
not have package versions that have been available since at least 2007. In
your case, it looks like your python installation is out of date (the
followlinks option is available since version 2.6). You could get around
that by removing that argument from the function call, i.e. change line 211
in 'build' from :
    for root, dirs, files in os.walk (os.path.split(self.name)[0],
followlinks=True):
to:
    for root, dirs, files in os.walk (os.path.split(self.name)[0]):

While this would sort out that particular issue, I would be very surprised
if it got you much further. I've tried on our CentOS 5.5 systems, and found
that a few other required packages are also a few versions out of date...
and gave up at that point.

So in brief, I'd say the path of least resistance would actually be to
upgrade the OS to the latest version of Ubuntu... Would also recommend
making sure it's got an nvidia card for the graphics, since the OpenGL
support for these cards is vastly superior to that for other cards (I've
just had another negative experience with an ATI card recently).

Another option is to use the Windows version, although I personally don't
have much experience with it. Maybe Win32 users could report back their
experience of MRtrix on Windows?

Cheers,

Donald.
