Hi all:
In qdec, when i left-clicked on a point of pial surface, there would be a
coordinate displayed at the bottom of qdec. my qestion is that does the
coordinate belong to the MNI space or talariach space?___

Hi, all, anyone knows that if the ICV in the aseg.stats means the whole volumes
inside the skull or the total volumes of GM and WM? Does it include the CSF
between the skull and the cortex? Thanks.

When using the norm.mgz, what is the best way to evaluate the accuracy of the
thalamus labeling? If lateral thalamus has low contrast with WM, how can we
tell where its borders should be? Or is it best to assume that the automatic
segmentation has done sufficiently well?

I see what you mean. Is it possible that they are the same direction?
When you look at the angle values when running them individually, are
they the same or opposite sign? Are you sure that the par file lists one
as positive and one as negative?

Hello,
I'm conducting a longitudinal analysis and encounter an error when
running the "long_mris_slopes" command (this is contained in the online
tutorial:
http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/LongitudinalTutorial).
The error that arises within a minute is "ERROR -10 : mris_calc
Gari, can you check whether you have ?h.BA.annot in your subject/labels
folder? this is an annotation of all the BA labels. They are
non-overlapping; overlaps are resolved by the one with the most
probability. I can't remember whether this made it into 5.1 or not.

what is it that is noisy? The angle map or the p-value map? Can you send
pics?

Hi Gari
they overlap as the labels represent every location that could possibly
be in either label. Unless we could predict them perfectly they have to
overlap, since they share a border. With 5.2 we will include different
default thresholds, but at the moment you have to do it yourself. You co
Hi,
I am currently analyzing some retinotopy data.
For the polar angle stimulus we had both clockwise and counterclockwise stimuli.
Both of them started at the top of the screen (12 o'clock), each run includes 4
full cycles and ends with the last wedge slightly before/after 12o'clock.
We have c
Hi Bruce,
thanks for your answer.
I am mapping a volume ROI (BA45) from SPM in MNI 152 space to fsaverage (the
result is the red ROI). The problem is that:
- when I load the BA45.label from FS in order to compare, they are not quite
similar. My main problem is to know if the differences are a

Hi Meng, the first row is what you want. The second row tests for an
interaction between diagnosis, genotype, and age.

Hi Colin
have you tried mri_convert? We did support bshort as a format (such as it
is!), although it hasn't gotten much use for years. Try something like:

Hi Gari
sorry, I'm a bit confused. Are you using the individual subject estimates
of 44 and 45 generated by FreeSurfer, or mapping them from MNI space? In
either case you can get overlap unless you pick the most probably label at
each point.
cheers
