WARNING! The default Freesurfer version that runs on CentOS6 machines is
going to change next Monday the 17th to a new CentOS6 specific version.
Right now at the Martinos Center we have a mix of CentOS4, CentOS5 and
CentOS6 machines at the center. All these currently use a version of
freesurfer built on CentOS4 for maximum compatibility. However, this
means those users with CentOS6 systems are using a version that is
slower than they could be using if properly optimized.
It is time for users of CentOS6 system to no longer be held back by the
older systems. So on next Monday the 17th, the default Freesufer on all
CentOS6 systems (which includes launchpad, tensor, and the icepuffs)
will be updated to a new CentOS6-specific build.
The mixed environment this results in can result in confusion for groups
with a mix of CentOS versions among their workstations. To avoid this
your group should do one of the following:
(1) contact the Martinos IT Help Desk to upgrade your old CentOS4
and CentOS5 systems to CentOS6. Sometime in the near
future we will drop support all together for the old systems.
(2) make a copy of the current CentOS4 release for your study into
your group's work area and point your users' environments to
use that copy. This is what is recommended for study
consistancy anyway and instructions can be found on the wiki at
http://surfer.nmr.mgh.harvard.edu/fswiki/MakingPrivateCopiesOfDistributionsNOTES:
(1) to tell what CentOS version your workstation is running, run
on it:
cat /etc/redhat-release
(2) you are using the default freesurfer release if your PATH has
in it directories that start with /usr/local/freesurfer.
This is a symlink that currently points to the CentOS4 release
on all Linux machines at the center but will change to point at
the CentOS6 release on all CentOS6 machines next Monday, the
17th.
Feel free to email me with questions.
