sorry, but the majority of the time is required. We're working to speed
things up, but it is complicated software with multiple nonlinear warps,
segmentation procedures, etc....

Hi Bruce and Pedro,
Thank you both for sending me your suggestions.
Just to let you know, because my .dcm (dicom) files had a space and two dots
in the filenames:
(e.g. "2008_12_08.ek -0035-0001-00001.dcm" )
(and using quotes around the file name or "\ " within the filename without
the quotes did not work with recon-all), recon-all truncated the filename
before the space as "2008_12_08.ek" feeding it to an mri_convert command and
gave an error message.
So I worked around this problem as follows: I converted the .dcm series to a
nifti .nii volume using 3D Slicer, and then used mri_convert to convert the
.nii format to .mgz format. Then I ran recon-all on the .mgz formatted file
and it is now running successfully.
I see on the online tutorials and slides, that this process takes about 20
hours. Is there a way to only run partial steps pertaining only to the
cortical thickness?
Pedro also suggested that I go through the FreeSurferBeginnersGuide wiki
which I am doing now.
Also, reading some mailing lists emails, I noticed that matlab can be used
to analyze the cortical thickness statistiics, and also freesurfer comes
with matlab scripts. I will try these tools out as well.
Thank you for your time,
John

Hi,
I am running freesurfer on 64 bit Fedora 10 linux.
I am using version:
freesurfer-Linux-centos4_x86_64-stable-pub-v4.3.0.
Can anyone point me to a reference web page listing what
steps I need to
type to process
a series of MRI dicom slices and use FreeSurfer to measure
cortical
thickness for this dicom series?
Thank you,
John
