Hi, I have a couple of questions I was hoping the list might help me with,<br>
<br>
1.&nbsp; I am using SuSE Linux version 10 (X86-64) and previously I had
been told that the redhat 9 release was the most similar to SuSE 10,
but with the release of the CentOS 4 X86_64 release I wondered if this
would be best to use.&nbsp; To that end I ran the same subject with
both the new CentOS 4 X86_64 release and the new redhat 9 release and
came up with different results.&nbsp; For example both the wm.mgz files
produced by the two releases have small but noticeable
differences.&nbsp; Is this because of rounding error due to the 64 vs
32 bit difference, and if so does anyone know which release would be
best to use, that is, is one going to give a better estimate, or are
both going to give slightly different, but equally good
estimates?&nbsp; If it's not due to rounding error what could be the
cause?&nbsp; <br>
<br>
2.&nbsp; I want to map automatic segmentation's to fsl feat
directories, but fsl uses LAS orientation, while freesurfer uses
RAS.&nbsp; Does the feat2anat or aseg/aparc2feat commands take this
into account, or should I swap the dimensions of one or the
other?&nbsp; If I should swap dimensions, would it be best to simply
put my structural scan into freesurfer in LAS format in the first
place, or swap things after all the freesurfer analysis has been
done?&nbsp; <br>
<br>
thanks,<br>
