This page describes the datasets on MCIN resources and requirements for access to these datasets. Some are available for all to use with no restrictions, but most need the user to be approved and added to a list of users.

Data Inventory Entries should include:

1. Heading = Dataset Name
2. 1-line Description
3. MCIN Contact Person
4. Reference Website
5. Version Number of release
6. Release Date
7. N_groups (eg. patients, healthy controls, genotype, ???)
8. N_subjects (total in each group)
9. N_timepoints (average, variance)
10. Modalities present
11. Brief summary of planned projects/analyses
12. Derived processed data
13. Requires access permission? (Data Access Agreement, MCIN approver)
14. License or link to license
15. Path (Including server)
16. Unix group https://contacts.acelab.ca/groups.php
17. Permissions - Raw data should be read only in order prevent data loss or alteration, Raw data directories need to allow r - - Ordered List Itemead and execute in order to allow users and programs to traverse the directory structure.

For different data types, please list the following as completely as possible:

18. Structural MRI

• DICOM or nii/mnc (+ version of conversion tool if nii/mnc)
• Magnet strength + manufacturer

• Diffusion (# directions measured) DTI BIDS: https://docs.google.com/document/d/1cQYBvToU7tUEtWMLMwXUCB_T8gebCotE1OczUpMYW60/edit
• Image size/voxel spacing
• Pre-processing applied?

19. Functional Imaging

• DICOM or nii/mnc (+ version of conversion tool if nii/mnc)
• Resting state (avg/variance in #/size of volumes, length, TR/TE time) + corresponding physiological data
• fMRI (avg/variance in #/size of volumes, length, TR time) Details of task, Stimulus available?, to classify the task use a cognitive ontology (e.g., https://www.ncbi.nlm.nih.gov/pubmed/21643732)
• EEG/MEG (# channels, time length (avg/variance), sampling rate) see EEG BIDS spec: https://docs.google.com/document/d/1ArMZ9Y_quTKXC-jNXZksnedK2VHHoKP3HCeO5HPcgLE/edit; iEEG BIDS: https://docs.google.com/document/d/1qMUkoaXzRMlJuOcfTYNr3fTsrl4SewWjffjMD5Ew6GY/edit

• Diagnostic label categories and distribution of subjects
• Age (avg/variance)
• Gender balance
• Number of data collection sites
• Other behavioural information available

23. Genetics:

• SNPs, WGS, RNA-seq etc.
• Format: bam, vcf etc.

24. N_subjects for each modality for each visit
