Group Analysis
by Nooshin Zadeh 18 Jun '13

18 Jun '13

Dear Freesurfer group I am interested to do group analysis on my data. If I want to do inter-individual group analysis, what is the minimum number of subjects I need to have? Also if I want to do intra-individual analysis, what is the best way in FS? I appreciate your time and your help. Thanks a lot, Nooshin

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
