Dear experts,

I analysing DTI, which I converted using MRICROGL . I am trying to find my readout time and I found the following problem:

1. According to my MRI technician, my readout time equals (48-1)*0.744= 34.968 so 0.035 in seconds (since there are 48 echoes and 0.744ms echo spacing in our acquisition).

Nevertheless, when I check the generated .json file when using MRICROGL, it says "TotalReadoutTime": 0.20094.
Which readout-time should I use then for topup and why are they different?

2. Also, this "TotalReadoutTime" seems to be slightly different between participants, is this normal?

Thank you in advance,

Ariadna
