Feuerstein,
One thing I noticed in the output is that there are 128 frames (NFrames = 128), which is unusual. Typically there is just one frame in a structural run.
Try running this command in the directory where your (Siemens) dicoms are located:
unpacksdcmdir -src . -targ . -scanonly scan.dat
this will parse the files and produces a file called unpack.log. look for the series that appears to be the structural, then type:
mri_convert <firststructuraldicom> 001.mgz
if that works (ie, tkmedit -f 001.mgz looks good), then use that dicom in the -i arg of recon-all.

Thanks for your advice.
Unfortunately, I first tried recon-all but failed with the same cause (number of columns in the mosaic (192) is not an integer multiple of the number of columns in the image (200); it is just to have a more detailed output that I used mri-convert (that I guessed to be the first step in recon-all).
All the best.

Bonjour Dr Philippe
My guess is "
Getting Series No
INFO: Found 250 files in /home/philfeu/freesurfer/subjects/ghca
INFO: Scanning for Series Number 2
Scanning Directory
INFO: found 128 files in series
INFO: loading series header info.
"
I think it should be better in the first runs that you convert your dicom in Alnalyze for instance using Mricro.
With the analyze file you generated from Dicom you can use mri_convert to convert it in FreeSurfer mgz and then follow the normal recon-all
I've seem sometimes my colleagues here having trouble with dealing with dicom structure when using FreeSurfer. I think this procedure helps in avoiding this problem and focusing on learning how to use FreeSurfer.
If you need any additional help contact me through the FreeSurfer Mailing.
Best Regards,
PPJ
2008/9/3 Feuerstein Philippe Philippe.Feuerstein@ghca.fr Hello,
I am evaluating FreeSurfer, installed and runned the tutorial without major troubles. Now, we have set up the MPRAGE sequence as stated here: http://www.nmr.mgh.harvard.edu/~andre/Sequences/SagMPR8Min.html and we have also a problem, surely a newbie and trivial one (sorry about that...). We had a series from a test patient, but initial stage of recon-all fails (in mri-convert) with the cause "ERROR: VolSS2MosSS: number of columns in the mosaic (192) is not an integer multiple of the number of columns in the image (200)" Here is the detailed log: ------------------------------------------------------------------------------------------- servux:~/freesurfer/subjects/ghca> recon-all -i C0001 -s test INFO: SUBJECTS_DIR is /home/philfeu/freesurfer/subjects Actual FREESURFER_HOME /home/philfeu/freesurfer Linux servux 2.6.24-19-generic #1 SMP Wed Aug 20 17:53:40 UTC 2008 x86_64 GNU/Linux /home/philfeu/freesurfer/subjects/test mri_convert /home/philfeu/freesurfer/subjects/ghca/C0001 /home/philfeu/freesurfer/subjects/test/mri/orig/001.mgz mri_convert /home/philfeu/freesurfer/subjects/ghca/C0001 /home/philfeu/freesurfer/subjects/test/mri/orig/001.mgz $Id: mri_convert.c,v MailScanner has detected a possible fraud attempt from "1.146.2.2" claiming to beMailScanner warning: numerical links are often malicious: 1.146.2.2 2008/03/02 02:53:20 nicks Exp $ reading from /home/philfeu/freesurfer/subjects/ghca/C0001...
