MACBOOK PRO M1 Monterey
by Dhari, Zaenab S 10 Mar '22

External Email - Use Caution Hello, For downloading the development version of FS which package of the ones available you recommend (attached screen shot), Since the new computer I have is Macbook Pro M1 Monterey ( brand new with no other OS installed other than its built in MacOS), I am not sure how compatible it with these Linux/Centos OS. I just have been reading people posts on random tech websites and it seems a bit tricky, any suggestions will be much appreciated. Thanks

External Email - Use Caution Hello Giuseppe, Try the same command (with lowercase w) or use a+w and then enter your password, $ sudo chmod -R  a+w  $SUBJECTS_DIRPassword: … then test to see if it works to create a file there, i.e., it should not report permission denied ... $ touch $SUBJECTS_DIR/foo … then see if you can remove the file … $  rm  $SUBJECTS_DIR/foo If that works you should be OK. - R.

Re: [Freesurfer] Oracle VM - SSH
by fsbuild 09 Mar '22

09 Mar '22

External Email - Use Caution Hello Zoe, The VM is not setup out of the box with an IP address you can use to remotely login to from an outside machine.  It uses (or piggy-backs off) the existing network connection from the host machine.   This enables the VM to boot w/o needing to negotiate for a non-local IP address and it is also for security.  We don't know the policy for someone connecting a new (virtual or real physical) machine to the network the host machine is already using.  If you can remotely VNC into your host machine and see/use the desktop, then you can use the VM running on the desktop as just another application. There’s information available online about how setup a VirtualBox VM to be accessible from the outside, e.g., via ssh.   If you have IT support, you could ask them for help.  But it’s not really practical for us to support users configuring a machine to run on their local network.

External Email - Use Caution Dear FreeSurfer experts, I'm trying to cut and flatten the full surface. I understand that tksurfer is deprecated and on my PC does not work properly. Is there an alternative way to perform the cuts?

Using T1 FLAWS in recon-all
by Mathilde Pichon 09 Mar '22

External Email - Use Caution Hello, I know T1 MPRAGE is the prefered format to perform a recon-all segmentation. But some of my patients' data only have FLAWS images and no MPRAGE images. So is it possible to perform a recon-all with FLAWS images ? Regards, Mathilde

bbregister dependencies recon-all
by Guillem París 09 Mar '22

09 Mar '22

External Email - Use Caution Hello, I'm trying to run a Boundary-based registration by using bbregister. In the documentation, it is specified that the anatomical image has to be previously analysed in FreeSurfer. I assume that means to run the "recon-all" pipeline. Now, are all the stages of "recon-all -all" needed to perform this registration? Since I am time-constrained, I would like to run as few stages as possible, so I can use bbregister. If it matters, I'm trying to register a DWI to the same subject's T1-w. Thank you! Guillem

Error: inputs cannot have multiple frames
by HYE JUNG YOUN 09 Mar '22

09 Mar '22

External Email - Use Caution Dear Freesurfer developers, I realised some of my recon-alls been processed with the following error: ERROR: input(s) cannot have multiple frames! /Users/mac_01/Desktop/1155_401/mri/orig/001.mgz has 2 frames (I have attached the recon-all.log) I checked the mri info and I think the problem is the dimensions which is 256 x 256 x 211 x 2. I'll attach the original commands I used with mri info in txt file in case it would help you to see where I went wrong. If anyone has been through this problem or if you know what I can do to fix this, please let me know. Best, H
