Ok - thank you! I will speak to the person who generated the files then.

I don't know how you (or someone else) generated the nifti files in the
first place, so I can't help there. If you did not generate them, then
talk to the person who did. I do not really recommend trying to do it by
hand. You can get AP and SI correctly, but you'll never know whether
they are L
Ah, I see - how would I be able to do either of those? And would I have to
check the geometry of each scan individually? Not sure how that works, but
I have a substantially large dataset.
Thank you for your response!

That means that geometry information (ie, what is left and right,
anterior or posterior) is not part of the nifti file. Without that
information, the anatomical analysis cannot be done. You will either
have to fix it yourself (ie, imbed that info into the file) or, better,
recreate the file wit
the nifti file does not have the needed information in it. where did you
get it from?

Dear Experts,
according to the log, Vasudev is using version 5.3-HCP. Therefore I expect that
he is running FreeSurfer inside HCP pipeline scripts. The problem is that the
use of 6.0 version with HCP pipeline scripts is not currently recommended.

This error is due to an incompatibility between the version of perl
shipped with ubuntu16 and the MINC tools shipped with freesurfer. This
issue has been fixed in freesurfer version 6.0, which I recommend you
download and install.

It was actually mri_nu_correct.mni. this is our script that calls some
MNIC programs. What version of MINC are you using?

Thanks Doug! What do you mean by registering to an individual? Is editing
the talairach registration for each individual subject not the same thing?

Hi Alex, it is fine to scale the brain for the tal registration. It is
when registering to an individual that one must be very careful with
scaling.

it won't affect any individual thickness measures, *but* will affect the

Hi Venkateswaran,
we don't apply the tal xform,just compute it (in
mri/transforms/talairach.xfm), so there is no volume "after talairach".

the final tal coords are the average of the corresponding surface regions,
where the correspondence is established using spherical registration. Does
that make sense?

If a bad talairach alignment prevents the creation of the surfaces (the
files in the subjects surf directory), then just exclude the '--surf
