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.

--Greg
