The document discusses functional magnetic resonance imaging (fMRI) data. It includes information on two participants in a study including their age and sex. It also includes details on the MRI sequence parameters used to collect the fMRI data such as repetition time, echo time, and flip angle. Finally, it mentions using mriqc validation software to validate an fMRI dataset in BIDS format.
