Hi Jesse,
The DTI images are not stored in a way such that unpacksdcmdir can do a proper error check and so it displays an error.
I think you can ignore the error.

I've noticed that an error is consistently reported in the unpack log file when I unpack dti scans for any subject:
INFO: this run has an error, but trying anyway
For example, if I try to unpack the dti scan for subject RMCON032, whose data is in /space/archive/216/siemens/TrioTim-35006-20090508-140454-440000, the dcmdir-info output is:

And I enter the command: unpacksdcmdir -src . -targ $SUBJECTS_DIR/RMCON032 -run 24 dti_test nii f.nii -fsfast -log dti_test.log
The unpack.log file contained the warnings and errors below (Also: I expected the log filed to be named dti_test.log so it wouldn't overwrite the unpack.log file I already had for the subject, but instead it was saved as unpack.log, overwriting the preexisting unpack.log)
WARNING: Run 24 appears to be truncated Files Found: 70, Files Expected (lRep+1): 120 FileName ./440000-000024-000001.dcm
Run 24 ----------------------------------------- Thu May 21 10:37:42 EDT 2009 24 dti_test nii f.nii INFO: this run has an error, but trying anyway
RunNo = 23 WARNING: Run 1 appears to be truncated Files Found: 70, Files Expected (lRep+1): 120 FileName ./440000-000024-000001.dcm
Are the dti scans I unpacked usable, or do I need to change my unpack command?
Thanks, Jesse
