There appears to be a problem when freesurfer reads in that dicom file. See if this works

mri_convert -it dicom /home/omid/freesurfer/subjects/IBS_raw/_orig_/csd/E703S2I1.MR /home/omid/freesurfer/subjects/IBS_raw/csd/mri/orig/001.mgz

Hello,

We have been having difficulties importing GE .MR files into FreeSurfer.

We have tried a number of methods:
1) directly importing .MR
2) converting to .IMG via BrainVoyager, then importing .IMG with .HDR
3) converting to .IMG via BrainVoyager and creating .MAT using SPM99,
then importing .IMG with .HDR and .MAT
4) renaming .MR to .DCM, then importing .DCM

Here is a summary of our problems:
1) autorecon1 exits with error
2) orig.mgz is in wrong orientation; T1.mgz is in correct orientation
but a "cosine info" error arises when loading in tkmedit; brainmask.mgz
is in wrong orientation; reconstructed surface is in wrong orientation
(i.e. not actually a hemisphere; appears oblique)
3) orig, T1, and brainmask are all in wrong orientation
4) autorecon1 exits with error

(in all cases except reconstructed surface, "wrong orientation" means:
    C = axial with anterior to the left and right to the top
    H = sagittal upside-down
    S = coronal with superior to the left    )

Here is a summary of what seems to be the source of our errors, from
corresponding recon-all.log files (I have attached .doc and .txt files
with longer excerpts)

We are now in the thick of attempting to manually import the volume from
.MR to .MGZ by using the load_mgh.m, load_mgh2.m, save_mgh.m, and
save_mgh.m scripts, but before pursuing that avenue further we would
like to seek some expert advice.
Any thoughts or suggestions would be greatly appreciated. Please let me
know if I can provide any more necessary information.

Thank you for your time,
