Choi's parcellation expansion inquiry
by 조수연 10 Feb '14

10 Feb '14

Hi, all. I'm trying to apply Choi's parcellations onto my subjects' data. I used the 7-Network loose mask but it turns out that even the loose mask isn't capable of covering up the ROI. Is there a way I can further "expand" the loose mask and make it "looser"? The uncovered areas of my subject's image are colored skyblue. The rest are parcellated segments of Choi's image. FYI Choi's FreeSurfer grid images were linearly transformed by concat matrix which shifts FreeSurfer grid to Standard MNI152 grid to our subject's grid. Thanks. Best regards, Sooyun.

How to combine attached commands into one run
by Erik Lindberg 10 Feb '14

10 Feb '14

Dear Freesufers, I want to use the following commands in my recon-all to try to improve my output some difficult images: -gentle to mri_normalize and -min_border_white 85 -min_gray_at_white_border 80 So far I only managed to do this by making one step at a time. I was wondering if there is a way to combine these commands so I do not have to run it step by step.

reporting bhvat value from lme
by Knut J Bjuland 08 Feb '14

08 Feb '14

Dear Freesurfers We are now finishing an article, where we have used linear mixed models included in FreeSurfer 5.3 for longitudinal changes between two-time points. We have used this model. Intercept(RF) + centered time+ group + group*centered time + sex(gender). Everything is clear except for one thing. When we used this contrast vector [0 1 0 1 0] to get longitudinal change for the study group, we get two bhvat values. How can we calculate these two bhvat values to one bhvat vaule in position two and four? Should we just add them together after we have been multiple them with the contrast vector, or add them as sqrt(a^2+b^2)? Best regards Knut Jørgen Bjuland NTNU

possible to do multi planar reformats of hippocampal subfields in freeview?
by Salil Soman 07 Feb '14

07 Feb '14

Hi, I am reviewing hippocampal subfield segmentation using freeview, and was wondering if there is a way to do multiplanar reformats so I can get reorient the cor/sag/axial planes to that of the hippocampus? Thank you. -- Salil Soman, MD, MS Postdoctoral Research Fellow - Stanford Radiological Sciences Laboratory Fellow - Palo Alto War Related Illness and Injury Study Center WOC Neuroradiology Attending - Veterans Affairs Palo Alto Health Care System

PET Partial volume correction
by Jonathan DuBois 07 Feb '14

07 Feb '14

Hi Freesurfer experts, I have been using freesurfer for surface-based PET analysis and was wondering if the method for voxel-based partial volume correction, used in the recent paper (Cortical surface-based analysis reduces bias and variance in kinetic modeling of brain PET data), was implemented with scripts available in the freesurfer package? If so, would you mind providing more details on what tools were used? As in the paper, I have 3T MRIs (reconstructed with FS) and BP data from controls scanned in a HRRT PET and reconstructed with a similar method. Thank you, Jonathan
