PETSurfer: pvc'ed and scaled output nifti image
by Sneha Pandya 12 Jun '24

12 Jun '24

External Email - Use Caution Dear team, I am using mri_gtmpvc to obtain PVC'ed regional data which we will use as an input TAC to perform kinetic analysis. In addition, we are also doing static SUVR analysis (sum of frames from 60-90 mins) in which I am scaling input PET data with gray matter cerebellum. In the output folder I see that upon scaling (when using --save-input flag) we get a scaled input image which can be used as SUVR. However, is this scaled image also PVC corrected or just scaled? If not, then is it possible to get PVC'ed and scaled nifti image? Thank you, Sneha

Does motion correction command mc-sess do censoring of high motion timepoints?
by Possidente, Thomas 12 Jun '24

12 Jun '24

External Email - Use Caution Hi there, I'm using this version of Freesurfer: freesurfer-linux-centos8_x86_64-7.4.1-20230613-7eb8460 I'm using mc-sess to run motion correction on some functional task and resting state data. I would like to perform censoring on high motion timepoints in order to reduce spurious correlations due to movement during connectivity analysis. My main question is: does mc-sess include censoring? If so, what are the threshold parameters? If not, are there any optional arguments to turn censoring on? If not, how do you recommend doing motion correction with censoring using Freesurfer? I know mc-sess uses AFNI's motion correction, just not sure if it utilizes censoring. Thank you, Tom

cluster area from mri_surfcluster and read_curv are inconstant
by wangzhiwei3233 12 Jun '24

12 Jun '24

External Email - Use Caution Dear Freesurfer experts, I got the area of a cluster by two methods, and found the results were inconstant. Method 1: During group level analysis, the individual surface was normalized to fsaverage. I exported the cluster area and label file by command mri_surfcluster. The command ws as followed: mri_surfcluster --in ./sig.nii.gz --subject fsaverage --hemi lh --centroid --annot aparc --thmin ${thp} --sign ${sigsignTemp} --no-adjust --minarea ${tharea} --sum area${tharea}.${sigsignTemp}${thp_infilename}.cluster.summary --o area${tharea}.${sigsignTemp}${thp_infilename}.cluster.nii.gz --ocn area${tharea}.${sigsignTemp}${thp_infilename}.ocn.nii.gz --olab $Dir_Subj_fMRI/$out_dir_group/$analysis/$contrast/label_area${tharea}.${sigsignTemp}${thp_infilename}/label Method 2: I calculated the cluster area using the label file outputed by mri_surfcluster via the matlab funciton read_curv. I did this to test the method for calculating the area of a label manually drawn by me. 1, I first got the area of each vertex by the command area = read_curv('../fsaverage/surf/lh.area'); 2, I red the IDs of vertices in the label file and added 1 3, I got area values of vertices in the label file and summed them. I found the areas calculated by the Method2 were much smaller(except one ROI) than the ones exported by mri_surfcluster as shown below. Area from Method 1： # ClusterNo Size(mm^2) NVtxs Annot 1 833.94 1999 postcentral 2 578.52 1300 precuneus 3 243.78 463 middletemporal 4 184.72 344 inferiorparietal 5 111.76 292 insula Area from Method 2： ClusterNumber Area(mm^2) NVtxs AnotomicalRegion 1637.39 1999 postcentral 2 480.44 1300 precuneus 3 140.37463 middletemporal 4 166.33344 inferiorparietal 5112.76292 insula What's the reason?

SAMSEG with recon-all
by Jones, Richard 11 Jun '24

11 Jun '24

External Email - Use Caution Hi, I have been looking to use SAMSEG to segment T1 and FLAIR images and then feed the segmentation results into the recon-all pipeline. The command I have been using is below:- /Applications/freesurfer/bin/samseg --t1w ./T1/Subjects/MP074.nii.gz --flair ./FLAIR/Subjects/MP074.nii.gz --hires --use-flair --normalization2 --fill --pallidum-separate --threads 4 --s MP074 --recon --refmode t1w The job completes without error and the segmentations look fine but when I look at the FLAIR images then images in the coreg and input folders in the subject directory are fine but when I look at the images in the mri directory while the FLAIR.prenorm.mgz looks fine the FLAIR.norm.mgz and FLAIR.mgz images are normalized T1 images with some of the neck clipped off and are indistinguishable from the nu.mgz image. The SAMSEG segmentation isn't affected since it uses the FLAIR image from the coreg directory but I'm assuming the issus with the FLAIr.norm and FLAIR images will have repercussions for the rest of the recon-all pipeline since I'm using the -use-flair option. Is that correct and is there a fix for this? I'm using a Mac Pro running version 12.6.8 (Monterey) of the Mc OS. I'm running version 7.4.0 of the Freesurfer software. I have attached the logfile and a pdf file showing some of the images. Richard
