My name is Sam Enumah and I am an undergraduate working
in the A.A. Martinos Imaging Center at MGH Navy Yard. I have become
familiar with Freesurfer's tkmedit function and I am able to analyze my
data once I am given a set of 144 MR dicom files. While the
mri_convert tool works for the dicom files that are on the local
machine, I cannot seem to get it to work for the files I have tried to
retrieve from a CD. The files on my local host machine all display the
extension ".dcm" while the files from the CD do not display a file
extension and are files with names that consist of 8 unique numbers
(e.g 48480095)
As you may know, when running mri_convert, the user need only input
one of the files in a series and it recognizes all the other files and
creates the desired output (in this case the ".nii" file type to be
read by tkmedit). However, when I tried to input these 8 digit file
names into mri_convert, I received the following error:
Desktop/dicom/08110217/12250000/48480995.dcmdcmdir = /autofs/homes/014/xmlentz/Desktop/dicom/08110217/12250000 Ref Series No = 805 ERROR: bits = 8 not supported.

I tried "mri_convert <filename> --in_type ge adc.nii" but kept getting the error: genesisRead(): can't determine file name format
Essentially, my problem is that I have roughly 1000 dicom files (as
evidenced by command "file" in terminal) without an identifiable
extension and I need to find a way to change these into one of any of
the set MR001.dcm - MR144.dcm to be read by mri_convert.
As it stands now, I don't know what series (average DC, isotropic, FA,
etc.) these 8 digit numbers correspond to so I'm unsure of how to
proceed. Suggestions?
Thanks for your time.
