External Email - Use Caution Thank you Douglas. That’s much clearer. I do however, have a subject without a gender disclosure. Would I set up my class and contrasts as: 5 classes: PatentientsMale, PatientsFemale, HCMale, HCFemale, HCNa then use contrast [0.5 0.5 -0.33 -0.33 -0.33 0 0 0 0 0 ...]? Best, Liliana

Call for applications: LINC fellows program 2024-25
by Yendiki, Anastasia 31 May '24

31 May '24

Dear FreeSurfers - Our BRAIN Initiative funded center for Large-scale Imaging of Neural Circuits (LINC)<https://connects.mgh.harvard.edu/> is seeking to name 2 undergrads and 2 postdocs from diverse backgrounds and/or under-resourced institutions “LINC fellows” for 2024-25. The applicants are expected to have a research mentor in their home institution, who will provide a letter of support for their application. During the LINC fellowship year, the LINC fellows will remain in their current program/institution, and engage in a research project that can benefit from remote access to the data and computational resources of the LINC project, and collaboration with the LINC investigative team. For eligibility and application materials, please see: https://connects.mgh.harvard.edu/outreach/<https://connects.mgh.harvard.edu/outreach/#research-teams> Thank you for sharing with any qualified applicants that you may know!

Re: [Freesurfer] License for FreeSurfer 5.x

External Email - Use Caution  Hello Rafa, If you take a look under, https://secure-web.cisco.com/1dfxSJC8JWSEz6n8dSa8oPi0pnwDlx9137h03BernH-2Q8… - you will see there is a Virtual Box ..vdi file for the 5.3.0 release,  https://secure-web.cisco.com/1RcGOCq2p6BYFO6rvNlcGnNuDdMKQaAC7luBVOPnx9yiqM… - but I think that Virtual Box image will be running CentOS6 (or some old version of CentOS).  At that time we did not build or provide releases for Ubuntu linux.  The version of CentOS in the VM and Ubuntu12 may use different versions of glibc so I’m not sure the packages with 5.3.0 binaries listed above will run on Ubuntu12. We advertise the following caveat about switching to newer/different OS versions, or upgrading to a different (newer) Freesurfer release built with different compilers.  Either of those changes will likely produce some difference in floating point math results. Important Note: When processing a group of subjects for your study, it is essential to process all your subjects with the same version of FreeSurfer, on the same OS platform and vendor, and for safety, even the same version of the OS. While we continue to work to ensure that results match across platforms, there are none-the-less system-level libraries that are OS dependent. An exception to this rule is that you may view and edit files across any platform or version, and run some post-processing tools (outside the recon-all stream) if you check with us first (for instance you may run the longitudinal processing with newer versions). But if it’s not an issue for you to run on an old version of CentOS instead of Ubuntu linux, then your best bet is to try and run the existing .vdi file listed above in the VirtualBox client - which you would need to download and install on your current Linux machine. -R.

Re: [Freesurfer] SynthSR problem
by fsbuild 28 May '24

External Email - Use Caution  Some commands such as mri_synthsr in previous releases, e.g., 7.4.1, use code built with Intel processor specific instructions that cannot run on an arm processor, i.e., there is not full backwards binary compatibility in that case using the Rosetta emulation environment on MacOS.  Hence the “illegal instruction” error. We do have a (more recent) development build on a Silicon Mac you can download via the link,  https://secure-web.cisco.com/1lWnZREm3JXXMeuMNsb_hOkyb2ipaBFlFN8u43RUzyQ6-c… .... it has not yet gone the the same testing as done for a release.  Please let us know if you run into issues trying it. - R.

freesurfer coordinate systems error: mismatch region hippocampal atlas in matlab and freeview for high resolution
by Le, Jarod 27 May '24

27 May '24

External Email - Use Caution Hello FreeSurfer Developers, I'm attempting to acquire the hippocampal subfields and nuclei of the amygdala using a high resolution of 0.333 mm3. However, when comparing the results of using the Freesurfer Coordinate System in matlab, using the reported tkrRAS to VoxCRS equation, and the results of Freeview, by manually inputting the tkrRAS, they report different subfields. We were wondering whether this the matlab coordinate system is getting rid of information or the freeview is adding information? How could get more precise information with the matlab coordinate system? When looking closely, it appears that VoxCRS coordinates can have multiple subfields within the same integer by slightly altering the tkrRAS coordinates and noticing the subfield region name change using freeview. For example, we have a tkrRAS coordinate of [-24.65, -7.82, -21.04]. Putting this coordinate into freeview it gives us an "Unknown" region. Using the matlab coordinate system, we first transform the tkrRAS coordinates into the high resolution tkrRAS coordinates due to the mismatch of volume between the lower and high resolution. Then we use, VoxCRS = inv(Torig)*[tkrR tkrA tkrS 1]' to get the VoxCRS and then check the volume to get the subregion. It gives us a "CA1" region. I have searched the archive of past problems. However, no similar problems have reported.
