Hi,
Caret experts
I
am a Caret newbie and have a few questions regarding mapping a customized
cortical parcellation scheme to a fiducial and/or inflated surfaces in Caret.
My
situation is that I created a mask with multiple cortical regions on a
population-specific template using Matlab codes and want to map this
parcellation scheme on a fiducial surface in Caret. So far this is what I have
done:
1) Segment the
template and created fiducial and inflated surfaces for the template. As
required by Caret, the brain is cropped, resampled and only left hemisphere is
created.
So,
my questions are:
1) What
preprocessing steps that I need to map the parcellation scheme on the
anatomical template, since they have different voxel sizes, origin and coverage
(the parcellation scheme still has whole brain coverage and matches with the
anatomical template in FSL).
2) When I try to
load the parcellation scheme as paint, I always get the warning message saying
the areal color file is needed to load paint. How can I get/create this areal
color file that corresponds to the parcellation scheme?
3) Based on my
search on tutorials, it seems no special preprocessing steps are needed for
functional/tractography results to be mapped to the fiducial surfaces.
Considering that the tractography results, for example, may have same problems
as the parcellation scheme that I have (different voxel resolution, origins and
brain coverage with the template, after the template is processed in Caret) am
I missing some documents that introduce the procedures required for this type
of mapping?
Any
inputs or suggestions will be greatly appreciated!
Leon
