Hi freesurfer experts,
I have recently begun to use freesurfer to do structural MRI analyses. I have been able to successfully process about 40 structural scans with recon-all thus far, but starting a few days ago, I started getting this error whenever I run recon-all:
WARNING: file /Users/alojos/Applications/freesurfer/subjects/sub_9999.dcm does not contain a Siemens ASCII header has this file been anonymized? ERROR: cannot unpack mosiacs without ASCII header Darwin nerc130622.local 14.5.0 Darwin Kernel Version 14.5.0: Mon Jan 11 18:48:35 PST 2016; root:xnu-2782.50.2~1/RELEASE_X86_64 x86_64
recon-all -s sub_9999 exited with ERRORS at Mon May 16 08:43:24 CDT 2016
Here are a few of the troubleshooting steps I’ve tried to track down the cause of the error:
- - Re-run recon-all with a couple of scans from my dataset that I have already successfully processed
- - Re-run recon-all the same datasets but on a different computer
- - Re-convert the scans from .ima files to dicoms in osirix, then run recon-all
For all of these steps, I have gotten the exact same error message. The files should be anonymized, since I used osirix’s “anonymize and convert” function to generate the dicom files (the scans were given to me as .ima files).
Any suggestions on what to try next?
Thank you!
