Hello, 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: [gordo:12250000] (nmr-std-env) mri_convert 48480995.dcm adc.nii mri_convert 48480995.dcm adc.nii $Id: mri_convert.c,v 1.146.2.3 2008/08/11 22:18:58 nicks Exp $ reading from 48480995.dcm... Starting DICOMRead2() dcmfile = /autofs/homes/014/xmlentz/Desktop/dicom/08110217/12250000/48480995.dcmdcmdir = /autofs/homes/014/xmlentz/Desktop/dicom/08110217/12250000 Ref Series No = 805 ERROR: bits = 8 not supported. Send email to freesurfer@nmr.mgh.harvard.edu 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. -Sam -- Sam Enumah Harvard College Class of 2010 Concentrator in Neurobiology senu...@fas.harvard.edu
