答复: ROI
by Jin Bo 07 Sep '17

Hi all, I am a new to Freesurfer. I am currently useing freeview to get ROI(small lesion) on 7T MRI, but the ROI can not display on surface(tksurfer patient lh inflated -overlay patient/label/fcd.label ). The terminal showed the following sentence: label stat field identically zero - setting to 1 However, it works well on 3T MRI. Thanks, Bo ________________________________ 发件人: Jin Bo 发送时间: 2017年9月6日 8:11:40 收件人: freesurfer(a)nmr.mgh.harvard.edu 主题: ROI Hi all, I am a new to Freesurfer.

combining a stroke lesion label with aseg.presurf.mgz
by miracle ozzoude 07 Sep '17

07 Sep '17

Hello FreeSurfer expert, I have a binarized stroke masks of 200 stroke patients that were hand traced. Since, we have a lot of patients, it will take a lot of time to edit the aseg.presurf.mgz. The stroke masks were drawn in the native space and I want to bring them into the freesurfer space, and combine with the aseg.presurf.mgz/stamp it onto the aseg.presurf.mgz and then run recon-all -autorecon2-noaseg -autorecon3. I have done the first part: 1) mri_convert -rl /subject/mri/brainmask.mgz -rt nearest stroke.nii stroke.mgz (use freeview to check the accuracy) I want to combine the stroke.mgz with the aseg.presurf.mgz in order to create a new ROI. what command should I use to accomplish this? Thanks Best, Paul

Why does nii2mnc fail with a neck-cropped-structural Image?
by Usman Ayub 07 Sep '17

07 Sep '17

Hi Freesurfer People, The aim is get ROI masks for my functional images and to achieve that for each of the subjects in my data, I am: 1. Running freesurfer for segmentation of structural scan, 2. Running feat analysis that would give me transformation matrices including structural2functional and then, 3. I am transforming my masks from step 1 to functional space using flirt. The first step requires me to use the actual structural image and the second step won't produce good results if I don't do brain extraction on the structural image. Now the problem is, for structural image of one of the subjects, I cannot get good brain extraction unless I use fslroi to crop the neck out first. And if I do that, the transformation matrices that I get using resulting bet image won't be usable with the freesurfer masks that I have obtained using the uncropped structural image. And if I try to use fslroi-cropped-structural-image with freesurfer, the nii2mnc command would produce this error: $ nii2mnc output_better.nii.gz > ** ERROR: nifti_image_read(output_better.nii.gz): bad dim[0] > Segmentation fault (core dumped) > I don't know how am I supposed to fix this issue. Thanks, Usman Ayub Sh

wm topological defects
by Manuel Delgado 06 Sep '17

06 Sep '17

Dear all: Regarding wm edits, it is shown in the tutorial how to proceed with "holes" that appear in the smoothwm.nofix. However, those holes do not necessarily affect the wm matter surface. So is it recommendable to check if holes in the smoothwm.nofix surface affect the real wm surface before correcting them? And, what is the purpose of the smoothwm.nofix, is it used for other issues? Thank you -- *Manuel Delgado Alvarado, MD* *Predoctoral Researcher* *Neuroimaging Unit, IDIVAL* *Avda. Cardenal Herrera Oria s/n* *39011 Santander, Spain*

Re: [Freesurfer] Ventricle Volumes Decreasing over time?

Hi Bruce, Thank you for your quick reply! The decrease in percent difference vary. I have listed the range here for each region: Left Lateral Ventricle: -26 to -0.06 Left inferior ventricles: -67 to -0.2 Third ventricle: -23 to -0.06 Fourth ventricle: -7 to -0.142 Right lateral ventricle: -21 to -0.04 Right inferior ventricle: -59 to -0.68 I had a chance to examine one brain that showed -16% difference score in the left lateral ventricles between the longitudinal and baseline scan. The scans seemed to show a smaller left lateral ventricle at time 2. Do you know whether the variability of Freesurfer (version 5.1) may contribute to some of the decreases I am seeing?

Hi Team, We would like to process the MRI data obtained using Philips and Toshiba scanners. Can we do it using Freesurfer?
