Hi All, There is a label named White-matter hypo-intensities (77), is it the same as white matter hyper-intensity? If not, can anyone tell me the difference? Thanks in advance, Akshay

DICOM unpacking error
by Luc Amdahl 17 Jun '13

17 Jun '13

Hi Freesurfers, I am trying to use Freesurfer to convert DICOM files to nii f.nii files. Freesurfer is able to find all the DICOM files but always gives me an error: "ERROR: reading DICOM/59175096 tag 28 30". Can anyone help? Thanks, Luc -- Luc Amdahl Brown University '14 Sc.B.

Editing Criterion
by R Duke 17 Jun '13

17 Jun '13

Hello Freesurfer Experts, I am relatively new to FS'r and was wondering if there were any references I could use to establish criteria for editing my results (pial surface, GM, and WM classifications). I am using two MPRAGE files (which gives me great results), but still would like to do some manual editing. Is this just left to the users discretion or would you all recommend a validated method that has been published? Cheers, R. Duke

correlation analysis
by stdp82＠virgilio.it 17 Jun '13

17 Jun '13

Hi list, I have performed cortical thickness analysis and I have individuated a ROI. Now, I'd like to perform a correlation analysis by qdec (if possible) between cortical thickness in this ROI and neuropsychological test score. I'm reading some previous post such as http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg12683.html,but I do not understand the passages that I should do. Please, may you briefly schematize the operation that I should do? Thank you very much, Stefano

Re: [Freesurfer] SPM ROI to Cortical Thickness
by McMains, Stephanie 17 Jun '13

17 Jun '13

I am wondering why you didn't tell them to go through fsvarege space? I thought that was an easy way to go from SPM MNI to freesurfer land. tksurfer fsaverage lh inflated -aparc -mni152reg -overlay /pathname/to/spm/roi/yourfile.img I am wondering because when I look at the segmentation for fsaverage, it seems like it is missing a lot of the gray matter, particularly in the big sulci, most likely from the 'smoothing' that comes with averaging subjects together. And therefore I wonder if this is the best thing to use as an intermediate step. Are you instead suggesting (as it seemed like in this thread), to put the SPM roi into individual subject space and then somehow project it to the surface in free surfer?

Visual Word Form Area and cortical thickness
by Garikoitz Lerma-Usabiaga 17 Jun '13

17 Jun '13

Hi list, I am interested in a Cortical Thickness analysis in the Visual Word Form Area. I have been suggested to use a MNI152 coordinate and make an sphere (circle in this case) of 5mm around it. Has anybody got any experience or any recommendation on how to establish the visual word form area for CT in freesurfer? many thanks in advance, Gari
