BrainVoyager Overview for Brain Imaging
Workshop 12/10/03
(http://psyphz.psych.wisc.edu/~greischar)
Version 4.9 for Windows only (One network license at Keck and one at Brodgen)
Input formats: ANALYZE, DICOM, GE (I-files or .sdt output from epirecon), User defined for pretty much any binary file.
BV can be scripted using Perl, VBA, Java, even Matlab.
BV creates its own internal
formatted fMRI (.fmr) and anatomical (.vmr) data sets.
It wants a power of 2 number of slices in your fMRI
data.
If your fMRI data is sagittal not all display options are
available.
It requires the source data to physically be in the BV
working directory.
fMRI and anatomical images are not automatically aligned
using header data.
BV uses fairly standard 2D and 3D
processing
3D rigid body (6 parameter) motion correction to arbitrary
volume (default first volume and scripting only allows default)
Transformation to Tailarach coordinates using AC,PC
alignment, then points AC,PC,AP,PP,IP,SP,LP,RP much like AFNI.
Creates 3D volume time course .vtc file using 2D-3D, AC-PC,
and Tailarach transfomations.
Gaussian spatial and temporal filtering.
General linear modeling (GLM)
No simple ability to export statistical maps (e.g. Analyze
format)
BV also includes:
Independent component analysis
Automatic segmentation, cortex surface inflations and
unfolding (flat maps)
Recently released multi-platform
BV QX
Unix, Linux, MacOSX, Windows (only able to get MacOSX and
Windows versions running)
Written using Qt C/C++ so now only supports QSA scripting
Supposed to support non-power of 2 number of slices and
sagittally acquired data
