Hi all,

I was trying to run freesurfer longitudinal analysis for my subjects at 2 time points and when I ran the pre_proc step it gave me an error that file ‘lh/rh.thickness is missing’. Here is what I have done.

1) Run the Freesurfer till CA Normalize stage (till norm.mgz stage).

2) Created unbiased template – log file showed ‘exited without error’ (and it looks fine)

3) Run longitudinal processing – log file showed ‘exited without error’ , but when I closely looked at the file there was following error:

#@# Talairach Failure Detection Wed Sep  4 14:22:01 CDT 2013

/work/02510/sray2/Free_Sub/FS_output/54062.long.54062_59467/mri

talairach_afd -T 0.005 -xfm transforms/talairach.xfm

ERROR: talairach_afd: Talairach Transform: transforms/talairach.xfm ***FAILED*** (p=0.0124, pval=0.0000 < threshold=0.0050)

Do you where is I am doing wrong. Why is the log file showing ‘exited without error’ if there was an error at Talairach Detection.

Please let me know.

Thanks,
