Hello, Freesurfers, I got an error message when I trying to use recon-all function in freesurfer on the XUbuntu system installed on the VirtualBox on a Windows 7 machine. I searched the e-mailing list but I can't find any answers.
My problem is related to the nu_correct and nu_estimate_np_and_em. However, nu_correct and nu_estimate_np_and_em were located to exact path (/home/virtualuser/freesurfer/mni/bin). echo $MNI_DATAPATH, echo $MNI_PERL5LIB showed exact path. In addition, I already tried to use fixup_mni_paths. Could anyone give me an advice for fixing up this problem? Thanks in advance. Cheers, EK error message! -------------------------------------------------------------------------------------------- #@# Nu Intensity Correction Wed Feb 15 01:23:24 EST 2012 mri_nu_correct.mni --i orig.mgz --o nu.mgz --uchar transforms/talairach.xfm --n 2 /home/virtualuser/Desktop/DATA/30664304/mri /home/virtualuser/freesurfer/bin/mri_nu_correct.mni --i orig.mgz --o nu.mgz --uchar transforms/talairach.xfm --n 2 nIters 2 $Id: mri_nu_correct.mni,v 1.18 2011/03/02 20:16:39 nicks Exp $ Linux FreeSurfer 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux Wed Feb 15 01:23:25 EST 2012 Program nu_correct, built from: Package MNI N3, version 1.10, compiled by nicks@fishie (i686-pc-linux-gnu) on 2010-02-20 at 20:19:13 tmpdir is ./tmp.mri_nu_correct.mni.17682 /home/virtualuser/Desktop/DATA/30664304/mri mri_convert orig.mgz ./tmp.mri_nu_correct.mni.17682/nu0.mnc -odt float mri_convert orig.mgz ./tmp.mri_nu_correct.mni.17682/nu0.mnc -odt float $Id: mri_convert.c,v 1.179.2.1 2011/03/22 16:37:02 nicks Exp $ reading from orig.mgz...
