Can you drop 1.3.12.2.1107.5.2.7.20409.30000007030804425018700002322.dcm to me at the file drop below?

Successful reconstructions have been realized for some of the subjects from one of the 2 centers, using their DICOMS (Siemens Trio), but we seem to be unable to use any DICOM from the other center (Siemens Allegra). It seems that the same problem has already been submitted to the mailing list, without any available solution : http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg01354.html
We get the following error messages (same on both computers):

- When trying to convert them with the MRI Convert software I get
the following error message : "Unable to find series UID"
- I can however convert them to nifti using SPM8 and MIPAV, and then
successfully run mri_convert and auto-recon1. I also tried to "save as dicoms" in MIPAV, but it didn't change anything.

So here are my questions :
- Is there something wrong with the command lines I wrote?
- Is there maybe something wrong in the files headers that I should
edit so that Freesurfer would recognize them as dicoms? or any other solution in order to use those dicoms? 3) If we were to use the nifti files :
- what would be the disadvantages?
- is there a risk of orientation problems with single nifti files?
with dual nifti files? should we check for L-R inversion for each subject after mri-convert?
- are there any concerns with comparing these subjects to our other
groups subjects (for whom we used the dicoms)?
Thank you very much in advance,
