Hello,

I have several errors using mri_convert to convert 3T Philips T1-wt, DTI and fMRI images. The last one on T1-wt images tells me to send email to freesurfer, so here is the error messages:

[pom@PomLinux /home/pom]% !mri mri_convert -it dicom -i IM_0001 -ot mgz -o 001.mgz mri_convert -it dicom -i IM_0001 -ot mgz -o 001.mgz $Id: mri_convert.c,v 1.179.2.2 2011/05/16 20:53:47 greve Exp $ reading from IM_0001...

Send email to freesurfer@nmr.mgh.harvard.edu

for DTI images, here is the errors:

I would greatly appreciate any help.

thanks so much
