What is the TotalReadoutTime of HCP dwi data?

#1

Hi,
I want to running topup to HCP dwi data with qsiprep. However, I get a error report about TotalReadoutTime. I converted the unprocessed data with hcp2bids. In the filed of TotalReadoutTime, it gives a 0.6. seem not right?

TotalReadoutTime = Echo spacing * (ReconMatrixPE - 1)
so, TotalReadoutTime=0.00078*(143-1)=0.11154?

Right?

This is the value I’ve used using the same calculation.
