What version of FS are you using? version 6 initializes with mri_coreg (the FS 
equivalent of spm_coreg). On whole-brain data, I've found this to be very 
robust. Is your data whole-brain?

Hi

I have a problem very similar to this one:

https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg23206.html

I've tried the suggestions given there, but it didn't fix my problem.

I'm running the FSFAST preproc-sess stream and the quality of the registration 
is very poor for most of the subjects.

I've tried initializing the registration differently, using bbregister with 
--init-fsl, --init-spm and init-header, which didn't improve the results at all.

I've also tried register-sess with --init-fsl, --init-spm and init-header, as 
well as spmregister-sess and fslregister-sess.

Is there anything else I could try?

Using the SPM GUI, the registration was fine, so I thought that 
spmregister-sess would have been an improvement, but it wasn't. Is there anyway 
I can import the registration obtained using the SPM GUI?

Thanks for your help.

Thanks,
Keri
