Hi Freesurfer experts,
I’ve run a PETSurfer analysis in order to compare mean uptake values of ROIs obtained with different methods: No PVC, SGTM, MG and MZ. However, I’ve now extracted the mean values and they are extremely heterogeneous. As an example, the same ROI (lh banks of the superior temporal sulcus) has the following uptake values:
No PVC= 1.709 SGTM= 2.495 MG= 23.847 MZ= 15.564
I’m particularly worried for the huge difference between noPVC - SGTM values and MG-MZ values.
Any advice? I wonder whether this finding is normal or there is something I’ve missed.
Many thanks,
Pilar

Can you send the recon-all.log file for some of the failures?

Dear list,
As described by others on this list, recon-all with Freesurfer 7.1 on a Mac operating system seems to fail for around 10% of the subjects.
The following solution was offered:
sudo curl https://raw.githubusercontent.com/freesurfer/freesurfer/dev/scripts/rca-long... -o rca-long-tp-init sudo chmod +x rca-long-tp-init However, this did not solve the problem for me.
I re-ran recon-all for the same subjects, but it still failed, some of them at the following step:
"####################################### GCADIR /Applications/freesurfer/average GCA RB_all_2020-01-02.gca GCASkull RB_all_withskull_2020_01_02.gca AvgCurvTif folding.atlas.acfb40.noaparc.i12.2016-08-02.tif GCSDIR /Applications/freesurfer/average GCS DKaparc.atlas.acfb40.noaparc.i12.2016-08-02.gcs #######################################"
It simply stopped running there.
Others did finish running, but instead got a segmentation fault error.
What could I do? I have Mac High Sierra.

I don't know what is going wrong here. One simple thing to check is to make sure that all the input files have the same number of vertices as the surface. If that is the case, then upload the subject and input files using the instructions below
From the linux command line, Create the file you want to upload, eg, cd $SUBJECTS_DIR tar cvfz subject.tar.gz ./subject Now log? into our anonymous FTP site: ftp surfer.nmr.mgh.harvard.edu It will ask you for a user name: use "anonymous" (no quotes) It will ask you for a password: use "anonymous" (no quotes) cd transfer/incoming binary put subject.tar.gz Send an email that the file has been and the name of the file.

Hi Doug,
I used FS 7.1 under WSL to analyze retinotopy data.? Since the ring and wedge were presented at a different frequency, the data had to be analyzed separately for each condition.? To get the field sign, I had to use the mri_fieldsign function to combine polar and eccen data. However, an error happened with running mri_fieldsign: ?Segmentation fault????? (core dumped)?.? The following is the command-line output.
Thanks for your help!

Hi Doug,
I have a question surrounding our attempts to extract PET binding values (BPND/DVR) which have been first transformed into FS subject space, mapped to the cortical surface using mri_vol2surf (signal averaged over the middle 80% of the cortical ribbon), and then displayed on the inflated hemisphere surfaces.
We would like to extract the average binding values from the cortical surface ROIs using the Desikan-Killiany atlas, but are unsure how to go about this. Is there a simple way to use aparcstats2table or a similar command to extract average values from surface ROIs as defined by the ?h.aparc.annot file?
Thanks!
