Hi, Bruce.
I am currently putting the file (Well-C0-T1w-023-20050425_124.zip) - it will
take a while.
I was able to make it a lot better using the Topological Defect correction in
tkmedit. Is it suitable for this task? I have not tried adding control points.
This is an older data with a
Hi Eileen - It looks like there was a A-P flip introduced to your gradient
vectors. (See screenshot of the tensor eigenvectors. Because they look
right in the coronal view but wrong in the sagittal and axial views,
that's why I'm assuming the flip is in the A-P direction.) To fix this you
Hi Anastasia,
Thank you very much for your answer, kindly I have one more question:
I wanted to use the path.pd for the corticospinal tract as an ROI in PET data.
What is the correct method to thrrashold the path.pd for the corticospinal
tract over the subjects. I.e in order to normalize all the
Hi Ping-Hong - The tracts are not registered, as opposed to a voxel-based
method. Here the measures are extracted in each subject's native space.
After tracula has derived the posterior probability distribution of the
path (in trac-all -path) it can find the maximum a posteriori (MAP) path,
Hi Emad - The error is:
dyld: Library not loaded: /usr/X11/lib/libGLU.1.dylib
Does the freesurfer build that you're using match the computer that you're
running it on?

Hi Janosch - Each tract has been labeled manually in a set of training
subjects. Based on these manually labeled tracts and the aparc+aseg of the
same training subjects, TRACULA computes the probability of a tract going
through each aparc+aseg label, or next to each aparc+aseg label in the L,
Hi Katherine - Did you specify the gradient table and b-value table in
your configuration file? I suspect that the issue is that it can't find
them.

I figured it out.
I wanted to relate a set of points on the pial surface to their

if you mean topological defects, those are always there. If the output
looks good you should be all set.

The 0 index is always unknown. What problem does the other issue

For some reason the spatial fwhm calculation is failing. This sometimes
happens if the mask is highly fractured. Can you look at
group.glm/mask.nii.gz and see if there are a bunch of isolated voxels?

There appears to be a bug in the computation of the fwhm and it appears
that I fixed the bug somewhere between 5.3 and now. I've put a new
version of mri_glmfit here

I am having trouble with the WM segmentation, several parts are excluded, its
due to the poor contrast. Is there a way i can change the contrast in

Hi all,
I am new to Freesurfer and have run my participants’ data through the
longitudinal preprocessing stream and am now trying to assemble my data so
that they can be put into a linear mixed effect model analysis. While the
longitudinal tutorial with cortical thickness data is very helpful,
Hi Shaheen
you can't change the contrast, but you can use the expert options in
recon-all to change what we expect in mri_segment and mris_make_surfaces.
