Installed spm 8 in /home/rcusack/software/spm_cbu_svn from CBU SVN repository. This is a convenient SVN format repository of the FIL's SPM neuroimaging software. Choose the latest version within the "releases" subdirectory. So for example, right now (Nov 2011), I type
>> addpath /home/rcusack/software/spm_cbu_svn/releases/spm8_fil_r4290.
and for aa
>> addpath /home/rcusack/software/aa/versions/release-4.0-beta
Installed spm 2 and spm 99 /home/rcusack/software. In case you're wondering, I'm trying to look at some old data!
To make these work on a modern 64 bit Linux server, I patched spm 2 with the spm 2 compiled files and recompiled spm 99 using spm_MAKE.sh gcc, adding "-fPIC" to the line CC="gcc -O2"
