Any other uses of the dataset are strictly prohibited. These restrictions are in-place to abide by the informed consent that participants provided for “broad consent for the storage and future unspecified use of data” as per TCPS 2 (2022), Chapter 3, Section E. To have the data available without restriction would require blanket consent, which is not permitted by TCPS 2 (2022).
To request access to the dataset, please submit the required form.
Once granted access, you will be added as a collaborator with read-only access to a private repository containing the ML-32M extension dataset.
You can read a copy of the README for the private repository, which describes its contents.
Please be patient, for at times I may be away from the office for periods of up to several weeks. If you haven’t heard from me in 2 weeks, you are welcome to email me.
