To achieve a precise normalization, we generated a study-specific SPECT template using both SPECT and MR scans of all patients and normal controls under study following a procedure described in detail elsewhere [ 21].
We used data from the Canadian Health Measures Survey (CHMS; cycle 1, 2007 2009), a complex-design survey that uses multistage probability sampling and oversampling of certain subgroups to generate a study sample that is representative of the general Canadian population (Statistics Canada 2011).
When a user retrieves a collection through the Pipeline database interface, the LONI Pipeline can automatically generate a study design module – e.g., an IDAGet or XNATGet module for retrieving all the neuroimaging data included in the study design module.
The appointments process will generate a study database to facilitate mailing of study packs directly to patients.
Structural images were brain extracted and GM segmented using FAST before being nonlinearly registered to the standardized Montreal Neurological Institute MNII) space to generate a study-specific template (Andersson et al. 2007).
This process generated a final study sample of FSWs of 5,498.
However, this study was performed as a pilot study, aimed to generate a larger study if any positive results were found.
Jang's [ 11] study also generated a control group, but this study involved the analysis of secondary data.
Second, it identified the important phenomenon of repeat victimisation, which generated a number of studies in the SCP mould.
