METHODS
-- Recruitment --
Healthy children were recruited via posters and word of mouth. Children were recruited between 6 and 13 years of age. Inclusion criteria were: 1) uncomplicated birth between 37 to 42 weeks' gestation, 2) no history of developmental disorder or psychiatric disease, 3) no history of neurosurgery, 4) no contraindications to MRI. All subjects provided informed assent and parents/guardians provided writted informed assent.
-- Data Acquisition --
All data was acquired at the Alberta Children's Hospital on a GE 3T Discovery MR750w system.
Participants were asked to return after 2 years to provide a longitudinal time point with the same scan protocol and cognitive examination battery. Some participants returned for a third visit, as they reached 4 years from their initial time point while the study was still actively acquiring data.
A battery of cognitive examinations was also collected during study visits. Exams were conducted in an isolated exam room with the examiner and participant only. Subtests from several studies were included in this battery, and administered if the participant was of appropriate age per subtest. This typically occurred during a separate appointment unless participants requested MRI and cognitive exam on the same day. The full list of subtests was:
- WASI-II
- Block Design
- Vocabulary
- Matrix Reasoning
- Similarities
- NEPSY-II
- Comprehension of Instructions
- Narrative Memory
- Phonological Processing
- Speeded Naming
- WIAT-III (Canadian)
- Early Reading Skills
- Reading Comprehension
- Math Problem Solving
- Word Reading
- Pseudoword Decoding
- Numerical Operations
- Oral Reading Fluency
- Math Fluency (Addition, Subtraction, Multiplication)

The following instructions require a basic understanding of UNIX/LINUX command lines. A subset of open datasets on the Portal are also available through a browser-based download button. The instructions below regard dataset download with the use of DataLad. To install DataLad on your system, please refer to the install section of the DataLad Handbook .
Note: For maximum compatibility with conp-dataset
, the CONP recommends versions 3.12+ of Python, 10.20241202+ of git-annex, and 1.1.4+ of datalad.
1) Initiate the CONP dataset
Run the following command in the directory where you want the CONP dataset (conp-dataset
) to be installed:
datalad install https://github.com/CONP-PCNO/conp-dataset.git
2) Install the AdolescentBrainDevelopment dataset
To install the AdolescentBrainDevelopment
dataset, run the following commands to move into the "projects" subdirectory under the "conp-dataset" directory (created in the previous step) and run datalad install
:
cd conp-dataset/projects
datalad install AdolescentBrainDevelopment
3) Download data from the AdolescentBrainDevelopment dataset
Now that the dataset has been installed, go into the AdolescentBrainDevelopment
dataset directory.
cd AdolescentBrainDevelopment
The files visible after installing the dataset but before downloading (in the next step) are symbolic links and need to be downloaded manually using the datalad get
command:
datalad get <filepath>
If you run datalad get *
command, all the files available in the dataset directory will be downloaded.
