Hi Freesurfers,
I am new to this software and i am trying to learn how to use it.
I have two questions:
1) if I do recon-all on a group of 20 subject, and I am primarily
interested in a few regions (In my case - amygdala, insula and anterior
cingulate cortex), do I have to edit all the datasets
Looks like you don't have
/home/virtualuser/freesurfer/subjects/lh.EC_average
You will need to download it

Thanks Bruce, from where? Should I download the other directories I seem to
be missing as well?

Hi Jenny
1) yes, they are usually fine, but you *always* should look at the regions you
are hoping to make biological statements about.
2) mri_convert -rl rawavg.mgz -rt nearest aseg.mgz aseg.rawavg.nii
Wold convert the aseg. Not that they are already in the original RAS space,

Which other ones? Grab a whole new distribution, unpack it somewhere and either
use it or move the dirs you need where you want them. Or wait a few weeks for

Hi Gabriel
Colin27 I believe has been reconned, and if not you can just run it and use our
standard tools for mapping. The others you can use the talairach.xfm for, but
it won't be terribly accurate. You can't use our training and labeling unless
you have the original datasets that went into
Hi Mojdeh
Have you checked out Koen van Leemput's hippocampal fled segmentation that you
can run through recon-all? It might do what you want automatically.

Hi there,
Sorry, if my question is confusing.
Hi Greg
What version are you using and what acquisition? There are some expert options
you could try like editing one volume and using it as an example for all
further intensity estimations

Do you know where I can download this
Is it not included in your freesurfer installation?

Hi Yuval,
while I have no real clue about your specific issues, it reminds e of an issue
we had in the past. We had used some condition names that start with a number
instead of a letter (e.g. 90degree) and the parsing code choked on that, as
it uses the first character of a field and tries to

It is already installed with Freesurfer as you say:

Hi Bryon - I was able to reconstruct the forceps major in your subject
after tweaking some of the 7 control points for the initialization. I'm
attaching the text file with the corrected control points - just drop it
in dlabel/diff and rerun the path reconstruction (don't use reinit,
though!)
Hi Arman - I changed one of your 5 controls points for the forceps major
to make sure that the initial path is well within the white matter,
following the approach I described to Bryon in my previous email. I'm
attaching the edited text file, please save it in the dlabel/diff/
directory of
Hi Prerona - As I've mentioned to others, you can ignore the Degenerate
spline segment message.
I can't tell what you mean by only traced a part of the trac. Can you
see the rest of it when you play with the threshold? Are you
reconstructing only the ILF? If not, do the other pathways look
Hi Prerona - I think this is explained in the archives on the same thread
as the bedpostx upgrade issue. If you run bedpostx outside of trac-all,
you should create dmri/data.nii.gz as a symbolic link to dmri/dwi.nii.gz
and dmri/nodif_brain_mask.nii.gz as a symbolic link to whichever brain

Thank you for correcting this. This in fact works. Alternatively after
re-running the pipeline with reinit=1 for so many times, as it tried
different initialization each time I managed to get the tract.
All the best,
