Hi Doug,
Thank you for your reply.
If so, then it cannot extract the bvecs and bvals. If you supply them in a file on the command line
I don't quite understand how --b works with dt_recon.
I did: dt_recon --i /Users/yuko/Documents/FreeSurfer/raw/AGY11ADTI/DTIs/IM-0011-0001.dcm --s AGY11 --o /Users/yuko/Documents/FreeSurfer/sessions/YDTI/YD11A
and it stopped after creating dwi.nii and dwi-ec.nii. I thought dt_recon is the command to compute bvals and bvecs. How do I supply bvecs and bvals on the command line?

Hi Yuko, your dicom file might be from a different versioned scanner than dt_recon is used to seeing. If so, then it cannot extract the bvecs and bvals. If you supply them in a file on the command line, it should run properly. doug

Hello,
I'm having a problem with dt_recon on data scanned by Siemens TrioTim. I'm using v4.5.0, with Mac OS 10.6.8.
dt_recon ran for a while, and stopped with an error "ERROR: cannot extract sWiPMemBlock.alFree[8] from /Users/yuko/Documents/FreeSurfer/sessions/YDTI/YD11A/dwi-infodump.dat"
I found the same errors reported to this mailing list, but found no solution. https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2011-August/019755.ht... http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg07935.html
In YDTI/YD11A/ folder, I have the following files dt_recon.log dwi-ec.ecclog dwi-ec.nii dwi-infodump.dat dwi.nii mri_glmfit.log
In dwi-infodump.dat, I see bunch of lines, but I don't see "sWiPMemBlock.alFree".
Please help! Thanks, Yuko Yotsumoto
