Dear Anastasia,
I have checked the image and it looks good. I don't think the image is
the problem, especially considering that my issue is also popping up
with standard data. See for example the following code:
$ echo $FREESURFER_HOME
/home/mriuser/privatemodules/freesurfer
$ cksum $(which mri_convert)
1305133180 29171478 /home/mriuser/privatemodules/freesurfer/bin/mri_convert
$ echo $FSLDIR
/home/mriuser/privatemodules/fsl
$ mri_convert ${FSLDIR}/data/standard/MNI152_T1_1mm.nii.gz test.mgh
mri_convert
/home/mriuser/privatemodules/fsl/data/standard/MNI152_T1_1mm.nii.gz
test.mgh

crypt_gkey = (null)

The reason I am posting this with 'Longitudinal TRACULA' in the title is
because I only have this issue with the mri_convert that is bundled with
the TRACULA update (see my first post). The original mri_convert bundled
with the centOS6 64bit version of FS 5.3.0 (stable) does let me convert
files. However, this version does not allow multiple frame numbers:
Original frame options of mri_convert (FS v5.3.0 stable centos6 64)
-f, --frame frameno
keep only 0-based frame number
Frame options of the updated mri_convert
(tracula.update.centos6_x86_64.5.3.2014_05_26.tar.gz)
-f, --frame frameno [...]
keep only 0-based frame number(s)
Longitudinal TRACULA pushes multiple files as arguments to 'mri_convert
--frame', which is why I need the updated version.
Do you have any suggestions for me?
Thank you!
best,
Vincent

Hi Vincent - Looks like an mri_convert error, so not specific to TRACULA
but
probably something about the format of your input nifti volume. How did you
create that volume? Can you open it in freeview and view it normally?

Subject: [Freesurfer] Longitudinal TRACULA: mri_convert
Hello Freesurfer experts,
I am trying to run longitudinal TRACULA but I am getting an error early
on in the process that seems to originate from mri_convert:
