Dhruman,

Try typing:

ldd $FREESURFER_HOME/bin/mris_volmask.bin

and look for the libexpat that it expects. libexpat needs to be in that directory. On 64bit Centos, it is looking for it in /usr/lib64, not /usr/lib. You could just make a symlink to the /usr/lib64 dir for that lib.

Hello All,

I have a library problem when I run recon-all. Recon-all exits with ERROR during the cortribbon step. I am using FC8 x86_64 OS on an Intel Xeon 64 bit machine. I have installed CentOS4-x86_64-v4.0.2 version of freesurfer. The library in question "libexpat.so.0" has been installed and is located in /usr/lib however, the problem persists. The command and error is:
