Hi Jessica
in general if you specify .nii or .nii.gz as the extension of any output
file we will write it in nifti format. This makes using mri_convert easy:
mri_convert any_volume.mgz any_volume.nii.gz
should work fine

the best way to remove intensity inhomogeneities is with control points

I encountered an error when running the test "Candal" dataset.

Hi Fraser
if you look at the mris_register help there is an option to specify a
manual label that corresponds to an atlas parcel:
-L
Specify a manual label to align with atlas label
in the past I have used this to draw a central sulcus and force it to align

Hi Frank
sorry, I've been busy with local deadlines that are over now. Can you send
us the recon-all.log file? Or tar and gzip the entire subject dir and
upload it to our ftp site? Apologies if any of this has been done.
cheers

I don't think our memory requirements change dramatically on a
per-subject basis. The one exception might be topology fixing, but if it
requires that much ram there are probably to many (or too large) defects to
succeed in any case.

Hi Doro
it's hard to tell from your image, but it looks like at least one of your
cps is not in wm but in the gm. This will mess everything up. Make sure
that they are in unpartial-volumed wm

Hi Dylan
I think you could probably do a recon without topology fixing although of
course the spherical mapping will then be multi-valued. It will take a bit
of hacking at recon-all to get it to work though as it is not a use-case
that we explicitly support.

should I look to get all these files?
The idea to check them is to confirm that the MRI went wrong at some point,
right?

Hi Gabriel,
that is a huge defect and generally means something major has gone wrong.
Look at the lh or rh.orig.nofix and the corresponding ?h.inflated.nofix
over the wm.mgz file to see what is wrong (usually something like a big

Hi Kate
the .lta format is for a linear registration (in ascii). YOu can just cat
it to see the contents - it is not a PET image (which will be stored in
.mgz or .nii). mri_convert or mri_vol2vol can be used to apply the
registration and/or change the output format (if you specify file.nii or
Hi Octavian
1. Not sure - you should try them. If you have reasonable surfaces I
think bbreg lets you specify masks to ignore, which should be giant help
in this scenario. On the other hand, mri_robust_register does this
automatically. They are both relatively fast so why not try and see?

tksurfer and tkmedit have been deprecated for a long time. Can you try
using freeview instead?
