Hi Michel, Our apologies for the delay in releasing these data. We had discovered technical issues with the recording of the external TTL trigger pulse in the Diffusion MRI sequences. For the physiological signals during Functional MRI, we utilized the external trigger recording to verify the internal timing flags in the pulse oximeter files. The nature of the technical issues in the recording of the external trigger during Diffusion MRI is making that process a bit less certain. We plan to investigate ways that we can verify the timing of the diffusion pulse oximeter data. Once we’ve reached a certain level of confidence in the timing information, we will release a data patch for the diffusion pulse oximetry data and a brief description of the process used to verify that timing.
