Hello,

I am attempting to convert dicoms into nifti files. The data I have are from a data consortium with multiple scan sites and thus it's not easy for me to trouble shoot how the dicoms are ordered/named.

subID=Pxxxx

Dimon -infile_pattern "${subID}*dcm" -gert_create_dataset -dicom_org -sort_by_acq_time -gert_write_as_nifti -gert_to3d_prefix ${subID}_rest -use_last_elem -save_details ${subID}_dimon_order

Dimon version 4.11 (March 13, 2015) running, use <ctrl-c> to quit...

-- scanning for first volume
-- reading 7799 image files ... 00%*+ WARNING: Bad DICOM header - assuming oblique scaling direction!

.

Is there an ordering convention that I am not aware of? I thought sorting by acq time would solve the problem.

Alternatively, I am checking with the data admin to see if the dicom is actually missing...
is there anyway to handle this situation if the file is missing?
