I think you need to ask that on the FreeSurfer list as that is not an HCP 
Pipeline issue.  Please tell them what version of FreeSurfer you are using.

thanks for the (very) quick response,
added to this mail is the log file

but actually I think now that the reason it carried out until the end is 
because I changed the 'set -e' to 'set -x' for debugging.
so, here is the error that arises when we just run it with 'set -e':

dyld: lazy symbol binding failed: Symbol not found: ___emutls_get_address

  Referenced from: /Applications/freesurfer/bin/../lib/gcc/lib/libgomp.1.dylib

  Expected in: /usr/lib/libSystem.B.dylib

thanks again

1.  You can get the gradient distortion coefficients from your scanner.  NONE 
can be set and for some scanners it does not make much difference (e.g. Trio).
2.  recon_all_seed is a random number seed.  Presumably this is an optional 
argument, but you could set 12345.
3.  Need to look at the recon-all log to see what failed.
4.  Give T1w and T2w from the ${StudyFolder}/${Subject}/T1w folder with 
acpc_dc_restore.

Subject: [HCP-Users] PreFreeSurfer and FreeSurfer pipelines questions

Hello dear experts

As I mentioned in an earlier message, we are trying to implement the HCP 
pipelines to our data, and we have a few questions.
After some struggling, we successfully ran the PreSurfer Pipeline we tried 
running the FreeSurfer Pipeline. we ran in with 'gdcoeffs' set to 'NONE', 
because we don't have any file with the gradient distortion coefficients. is 
that a problem?

After running the PreFreeSurfer, we tried to run the FreeSurfer pipeline, but 
didn't really know what to put as the 'recon_all_seed', so we tried to run the 
script without giving it any input.
The script somehow completed running "successfully", but without producing 
anything really - the 'surf' folder in the subject's dir is completely empty...
Which brings us to our question - what is the necessary input for 
'recon_all_seed'?
And another question just to make sure - the t1 and t2 images we should give 
the FreeSurfer pipeline are the acc_dc_restore ones, right?

Hope to hear from you
Shachar Gal, Tel Aviv University
