Hi,
I got an error during the first step in recon-all (Mac OS 10.6.8, FreeSurfer v5.1.0). The eror message in the log file is:
WARNING: file ...../MR.1.3.12.2.1107.5.2.18.41016.201008031106017688438785.dcm does not contain a Siemens ASCII header has this file been anonymized? ERROR: cannot unpack mosiacs without ASCII header.
This is strange because it is no mosaic file and all the files can be converted without any problems with e.g., dcm2nii and viewed with OSIRIX.
Cheers, Ed
