Hi, I have multiband dwi data acquired with a Siemens scanner and I successfully converted most of these data using dcm2niix version v1.0.20211006. However, a sizable amount of participants did not convert correctly- I received the error message in the attached screenshot. 

Does this suggest an error in data collection or conversion? If the problem lies within the conversion process, what do you suggest I do to address it?

I appreciate your time and assistance!
