'''Q: After I installed EMAN 1.8 on Fedora Core 6, I get this error message when I type eman: "EMAN/lib/libqsci.so cannot restore segment prot after reloc: Permission denied"?''' ''' ''' The solution comes from this link: [[http://www.ittvis.com/services/techtip.asp?ttid=3092|http://www.ittvis.com/services/techtip.asp%3Fttid%3D%33%30%39%32]]. The best way is: {{{chcon -t texrel_shlib_t YOUR_EMAN_DIR/lib/*.so}}} or you can Disabling SELinux altogether by setting the line SELINUX=disabled in your /etc/sysconfig/selinux file. But this is not recommanded.
