Notes:
Preprocessed images of the Bipolar Disorder with psychosis subjects
group (N=19) from the article: Frazier JA, Hodge SM, Breeze JL,
Giuliano AJ, Terry JE, Moore CM, Kennedy DN, Lopez-Larson MP,
Caviness VS, Seidman LJ, Zablotsky B, Makris N. Diagnostic and sex
effects on limbic volumes in early-onset bipolar disorder and
schizophrenia. Schizophr Bull. 2008 Jan;34(1):37-46.
This is the third release of a set of imaging and segmentation
results related to this paper.
The release is provided as a gziped tar file of a set of
directories containing the data.
The root directory is for the paper, SchizBull_2008/, and contains
subdirectories for the 4 diagnostic groups: Healthy Controls (HC),
bipolar disorder without psychosis (BPDwithoutPsy), bipolar
disorder with psychosis (BPDwithPsy) and schizophrenia spectrum
(SS). Each of these subdirectories will contain separate
subdirectories for each subject. These subject directories will
contain the CMA preprocessed image that was submitted to the
anatomic segmentation process, and the results of the general
segmentation and cortical parcellation (when available). These
files will be NIfTI.gz and called {$SUBJECT_ID}_{$TYPE}.nii.gz;
where $TYPE will be 'procimg' for preprocessed images, 'seg' for
general segmentation, and 'parc' for cortical parcellation results.
The seg and parc analysis results are 'n-ary' images, where the
fill value represents the specific anatomic region.
As this and additional sets of data are released as tar.gz files,
they will 'unpack' onto the same directory structure and fill in
the released subset of data.
The nature of the CMA preprocessing includes positional
normalization to put the image into the standard orientation of the
Talairach coordinate space, and bias field correction as described
in: Worth AJ, Makris N, Patti MR, Goodman JM, Hoge EA, Caviness VS
Jr, Kennedy DN. Precise segmentation of the lateral ventricles and
caudate nucleus in MR brain images using anatomically driven
histograms. IEEE Trans Med Imaging. 1998 Apr;17(2):303-10.
Diagnostic group basic demographic information is provided in the
diagnostic subdirectory in a .csv file entitled
{$DIAG}_Basic_Demographics.csv. This file contains age, gender, and
handedness for each of the subjects in the diagnostic group.
