Re: [Freesurfer] Problem with FS 7.1.2 binaries: libcrypt.so.1: version `XCRYPT_2.0' not found

External Email - Use Caution OK, thanks for the feedback.  I was going to suggest “sudo apt-get update”.  Upgrading can also help, though might not always be needed, but good to hear everything works now after those steps and installing the .deb package. - R.

External Email - Use Caution Hello Luis, This looks like an issue reported after people upgraded their Ubuntu systems causing the linker to find the wrong version of that library, e.g., https://secure-web.cisco.com/1CpmNJNH8pzSL1hJLa-ZTGnKU7d3M4tiDWoGYjpeLYrLel… https://secure-web.cisco.com/1clrdFLQBdqfAUq5LKlEmqt_gldQ1QZdh66JUXfxroxEcE… As of the 7.2.0 release, there is a .deb installer package you can use if you have admin/root privileges.  If there is an issue with the wrong version of libraries on your system, running the installer might update them. $ wget https://secure-web.cisco.com/1BtJUISuwmua9sN1tMsVUil68Clx5N6mnuRI… $ sudo apt-get install ./freesurfer_7.2.0_amd64.deb - which should give you /usr/local/freesurfer/7.2.0 You can always uninstall it. - R.

Inflated surfaces on FS7 looking different
by DIANA ORTEGA CRUZ 02 Nov '21

02 Nov '21

External Email - Use Caution Dear FreeSurfer team, I am experiencing a display problem in the FreeView version of FreeSurfer 7 for inflated surfaces. The inflated surfaces from my fsaverage folder look as in the screenshot attached, missing the gyri and sulci coloring and having a see-through pattern. My FreeView version is 3.0 Build Jul 23 2020. One of my colleagues tested opening inflated surfaces using different versions of FreeView, and these also look see-through using a version from FS7, but not using a version from FS6. Have any of you encountered a similar display for inflated surfaces? Do you know if this could be changed? Any advice would be much appreciated!! Thanks a lot. Best, Diana Ortega Cruz.

Re: [Freesurfer] Base correction, longitudinal analysis
by Eszter Boros 01 Nov '21

01 Nov '21

External Email - Use Caution Thank you for your answer! I think I should clarify this question a little bit. So this is about correcting the Base. And run recon-all *after *correcting the Base. What command should I use here? if I want to regenerate only the Base after correcting it? Because the common below does not work: (ERROR: must specify subjects for base subject using -base-tp) recon-all -base OAS2_0057 -autorecon-pial But if I use "recon-all -base OAS2_0001 -tp OAS2_0001_MR1 -tp OAS2_0001_MR2 -all" that just creates a new Base based on the cross MR1 and MR2. My question is how can I regenerate the corrected Base? What command should I use? Thank you so much!

Registering DTI fiber tracts (from MRtrix3) to FreeSurfer registered surfaces.
by Sherin Sugathan 31 Oct '21

31 Oct '21

External Email - Use Caution Hi!!, I have a two time point brain dataset of a single patient. The data consists of structural and DTI for both timesteps. I run FreeSurfer on each timestep separately for generating brain surfaces. When I display the brain surfaces(from both timesteps) together, they were appearing unregistered. Then I figured out that I need to use*FreeSurfer Longitudinal*to fix the registration problem. If I use FreeSurfer longitudinal, then it will most likely register both time point data to a common template, and my registration problem will be solved. I also want to display fiber tracts generated from MRtrix3 along with the brain surfaces generated by FreeSurfer. The problem is that the DTI data will not be touched by FreeSurfer. I am anticipating that this will become a problem to display fibertracts and brain surface properly. Please see below table that shows the data discrepancy I am expecting: |+----------------------------------+-----------------------------------+ | time t0 | time t1 | +----------------------------------+-----------------------------------+ | T1.nii(registered by FreeSurfer) | T1.nii (registered by FreeSurfer) | | DTI.nii (unregistered DTI image) | DTI.nii (unregistered DTI image) | +----------------------------------+-----------------------------------+ | FreeSurfer only takes in the structural data for brain surface generation and it leaves the DTI image untouched. Later, the fiber tracts generated using MRtrix3 won’t align with the FreeSurfer surfaces. How can fix this problem? Do you think it is possible to fetch some transformation and apply to DTI fiber tracts to fix the issue? Thanks in advance Reshma

Magnetization Transfer Images and recon-all
by Marlene Tahedl 31 Oct '21

31 Oct '21

External Email - Use Caution Hi! I have a couple of Magnetization Transfer MR images from a group of patients which I would like to analyze using the FreeSurfer pipeline. However, when applying "recon-all" to those images, the algorithm stops after just a few minutes. Although it says "finished without error", no images have been produced. Is there a way to apply recon-all to MT, maybe some conversion to make the MT images look more like a T1? Thanks! Marlene.

I don't think there is anything specific for the --table option, but everything else is the same.
