why are you running xhemireg for fsaverage?

I updated all the xhemi scripts following: http://www.freesurfer.net/fswiki/Xhemi but unfortunately the problem persists for fsaverage, since norm.mgz does not exist for fsaverage. I'm going to try creating norm.mgz for fsaverage to see if xhemireg works. Even if it doesn't, xhemireg does work for my other subjects, so I'll be able to find a solution.

Thanks for your help,

Andrew

when did you update the xhemi scripts last? Do a search on our
wiki for xhemi to get pointers to the most recent ones

Thanks Doug!

However, now I'm getting the following error:

/Resampling

Output registration matrix is identity

mri_vol2vol done
ERROR: canot find norm/

I am running:

/xhemireg --s fsaverage --reg/

Any suggestions? Should I run the following from
$SUBJECTS_DIR/fsaverage/mri/?

mri_nu_correct.mni --i orig.mgz --o nu.mgz --n 2 --uchar
transforms/talairach.xfm
mri_ca_normalize -mask brainmask.mgz nu.mgz
$FREESURFER_HOME/average/RB_all_2008-03-26.gca
transforms/talairach.lta norm.mgz

Hello,

I'm having a problem similar to the one outlined here:
https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2012-June/024182.html

When I run xhemireg I receive the error "ERROR: Option
--keep-precision unknown"

I looked for the newer version of mri_vol2vol
described in the
previous post, but could not find it on the ftp site. Any
suggestions?

Andrew
