Phillips DICOM to .nii conversion error
Hello,
I'm working with a set of 4D Flow MRI data acquired on a Phillips scanner. When attempting to convert the single folder of DICOM images using the MRIcroGL dcm2niix package I'm met with the following message:
I've read the previous forum post (https://www.nitrc.org/forum/message.php?msg_id=27724), but I've verified that my data (~/dcm) is not contained in subfolders (~/dcm/a; ~/dicom/b; ~/dicom/c). Additionally, I don't have information about the MRI sequence being downloaded from the machine so I'm not able to verify that all the files were copied correctly or that the sequence was interrupted mid-volume.
However, I am wondering if there is any way for me to work through this error assuming that all the files were obtained correctly and the sequence was uninterrupted.
Thank you for your help!

Warning: Unable to determine slice direction:
please check whether slices are flipped
Convert 1108 DICOM as C:\Users\YYY\Documents\XXX\4DFLOWanon_4D-TRANCE_20200729000000_701 (336x336x1108x1)
Saving as 32-bit float (slope, intercept or bits allocated varies).
Unable to equalize slice distances: slice order not consistently ascending: [dx = [0 0 0 ... 90.35]
Recompiling with '-DmyInstanceNumberOrderIsNotSpatial' might help.
