16 Mar '16

Good morning, I apologize if this email was sent out twice. I would like to use anterior to posterior length as a covariate in my DTI analysis. Is there an easy way to obtain this information for each subject? Thank you, Heather

error while running dt-recon all
by Jasmin Alves 16 Mar '16

16 Mar '16

Dear Freesurfer experts, FREESURFER_HOME: /Applications/freesurfer Build stamp: freesurfer-Darwin-lion-stable-pub-v5.3.0 Kernel info: Darwin 14.5.0 x86_64 I received the following error while running the dt_recon --i 00010001 --s 40 --o /Users/jasminalves/Desktop/data/FREESURFER/40. The participant is 40. And I received the following error: WARNING: file /Users/jasminalves/Desktop/data/40/00010001 does not contain a Siemens ASCII header has this file been anonymized? ERROR: cannot unpack mosiacs without ASCII header I did notice on previous threads this is a common error that occurs, but the files I have were directly exported from our siemens scanner via Osirix. I also tried running dt_recon using nifti format but that resulted in an error as well. Is there anything else I can do? Thanks, Jasmin -- Jasmin Alves Predoctoral Student Medical Biology Graduate Program University of Southern California jalves(a)usc.edu

Re: [Freesurfer] Editing Lesions in FreeSurfer 5.1
by Allison Rainford 15 Mar '16

15 Mar '16

Hi Bruce, I?ve attached a screen shot of a temporal pole of one of the brains that we have had issues with. Here the issue is that there is a lesion without a very clear boundary for the white matter and freesurfer was unresponsive to simply using white matter edits (placing 255s on the wm.mgz), and so we tried placing control points where we think the white matter boundary should lie. However, we know that control points should not be placed in these dark spots of a lesion. Thank you, Allison
