Hello,

I'm encountering issues while trying to convert DICOM files to NII files using dcm2niix(version v1.0.20230411  Clang14.0.0 ARM (64-bit MacOS)), due to some warning messages. I'm processing data from two different centers, and they are showing different warning messages.

For the first center, which used a MAGNETOM Trio scanner, I'm getting the following warnings for image types of EPI, REST and DTI.

Warning: Weird CSA 'ProtocolSliceNumber' (System/Miscellaneous/ImageNumbering reversed): VALIDATE SLICETIMING AND BVECS

Warning: Assuming mosaics saved in reverse order due to 'sSliceArray.ucImageNumb'

For the second center, which used a MAGNETOM Vida scanner, I'm getting the following warning for EPI and DTI data:

EPI and DTI appear to have

CSA slice timing based on 2nd volume, 1st volume corrupted (CMRR bug, range 8350..9085, TR=835 ms) / CSA slice timing based on 2nd volume, 1st volume corrupted (CMRR bug, range 44800..47837.5, TR=3200 ms

Even though these warnings are appearing, the NII files seem to open correctly. I will be using EPI and DTI images, so is it safe to proceed with the analysis as is? If there might be an issue, what kind of processing can be done? I've attached the JSON files as well.

Thanks in advance.
