repeated measures ANOVA 2x2 two groups two times {Disarmed}
by Agurne Sampedro Calvete 06 Nov '20

External Email - Use Caution Dear Freesurfer experts, I am trying to do a longitudinal repeated measures ANOVA 2x2, with two groups (experimental vs control) and two time points (pre and post treatment). Although I have run a paired t-test, now I would like to do a repeated measures anova 2x2, since I am doing the same analyses with other data in other softwares. I am trying to follow the tutorial https://secure-web.cisco.com/1xcEvqAuPN3MsqK1JjC6qoZbooZS3kpB4WEU1Lx8hK28gr…, but I have several doubts when designing the FSGD file as well as the contrasts. How should it be the FSGD file? I have seen in a previous post the following design for the same number fo groups and time points: GroupDescriptorFile 1 Class Subject1 Class Subject2 Variables Tp1vsTp2.GrExp Tp1vsTp2.GrControl Input Subject1_time1 Subject1 1 0 Input Subject1_time2 Subject1 -1 0 Input Subject2_time1 Subject2 0 1 Input Subject2_time2 Subject02 0 -1 Design matrix: 1 0 1 0 1 0 -1 0 0 1 0 1 0 1 0 -1 Contrasts (.mtx files): Tp1vsTp2.GrExp 0 0 1 0 Tp1vsTp2.GrControl 0 0 0 -1 Interaction 0 0 1 -1 Would this design be the correct one to use in this case? Alternatively, could it be this the correct one? GroupDescriptorFile 1 Class Subject1 Class Subject2 Variables Tp1vsTp2 Groupxtime Input Subject1_time1 Subject1 1 1 Input Subject1_time2 Subject1 -1 *-1* Input Subject2_time1 Subject2 1 *-1* Input Subject2_time2 Subject02 -1 1 Design matrix: 1 0 1 1 1 0 -1 -1 0 1 1 -1 0 1 -1 1 Contrasts (.mtx files): Tp1vsTp2 0 0 1 0 Groupxtime Interaction 0 0 0 1 Thank you very much in advance.

MRI SNR

External Email - Use Caution Dear expert We are planning multi-center study with the hearing impaired patients using FreeSurfer. The signal-to-noise ratio (SNR) of the test MRI from a center does not look very good, but the FreeSurfer can analyze the gray matter. How much the allowable SNR for FreeSurfer analysis? This is the MRI protocol and the test image. Thank you in advance.

Freesurfer 7.1.0 on CentOS 8.1

External Email - Use Caution Hello, I’ve seen a couple mentions on the list-serv about difficulties using Freesurfer on CentOS 8. My issue is likely similar, but I have a few more details. I downloaded freesurfer-linux-centos8_x86_64-7.1.0.tar.gz. When I launch `freeview`, it pops up a white/empty X window for a moment and then quickly disappears. E.g. $ freeview MESA-LOADER: failed to open swrast (search paths /usr/lib64/dri) libGL error: failed to load driver: swrast Aborted (core dumped) I vaguely recall that the libGL errors _aren’t_ fatal. I’ve seen them with other X applications. Digging around the abort logs, I found the stack trace (see end of email). Do you have thoughts on this? I thought it might be a VTK compatibility issue, but that is a guess at best.

[FreeSurfer] Two Postdoctoral Fellowships in Aging and Alzheimer's disease {Disarmed}
by Hwamee Oh 05 Nov '20

05 Nov '20

External Email - Use Caution We are seeking two highly motivated postdoctoral researchers to lead NIH-funded projects in the Laboratory for Cognitive and Translational Neuroscience directed by Dr. Hwamee Oh at Brown University. One position is to use fMRI and PET to study visual memory networks in healthy young, cognitively normal older adults, and older adults who are considered as preclinical Alzheimer's disease. The other position is to understand the brain networks that underlie risk and resilience to aging and Alzheimer's disease in a 60-year longitudinal study cohort. Applicants with a Ph.D. degree in cognitive neuroscience, neuropsychology, biomedical engineering, or a relevant field are encouraged to apply. Prior experience with human neuroimaging, a strong background in cognitive neuroscience and experimental design, and/or familiarity with programming in relevant languages (e.g., Python, MATLAB) are required. The expected start date is July 2021 or negotiable. A link to the full description of the fellowship positions can be found here under "Research Fellowship Program": https://secure-web.cisco.com/1OPjthLpBzhYKFTSwjkVOmEIR06WelLxkClkKQkPxS4xR8… . A deadline for early decision applicants is December 11, 2020, and a regular decision deadline is January 4, 2021. More details can be found: https://secure-web.cisco.com/1nI5zbsgp-rII9YGTnQVPZOgDTWuOf1k9XnIzMiA-caXOK… . Interested applicants are strongly encouraged to email a brief description of research background and career goals, and CV with a list of 3 references to Dr. Hwamee Oh at hwamee_oh(a)brown.edu.

Different Sequences Longitudinal Stream {Disarmed}
by Backhausen, Lea 05 Nov '20

05 Nov '20

External Email - Use Caution Dear FreeSurfer experts, I am currently working on a longitudinal data set with 4 time points, acquired at one site with the same Siemens Trio 3T scanner. Unfourtunately, the T1 sequence differs slightly for one of these time points. These sequences have been measured: 1) repetition time (TR) = 2300 ms, echo time (TE) = 2.93 ms, inversion time (TI) = 900 ms, voxel size = 1.1 x 1.1 x 1.1mm, flip angle = 9°; matrix size = 256 x 256 x 160 mm 2) repetition time (TR) = 1900 ms, echo time (TE) = 2.26 ms, inversion time (TI) = 900 ms, voxel size = 1.0 x 1.0 x 1.0mm, flip angle = 9°; matrix size = 256 x 256 x 176 mm Is it possible to process these different sequences in the longitudinal stream (if e.g. one participant would have 3 data sets of sequence 1 and one data set of sequence 2)? Or would this cause too much bias? Thank you very much, kind regards! Lea Backhausen ------------------------------ Lea Backhausen Ph.D. Student (M.Sc.

LGI quality control {Disarmed}
by Nelson, Eric 05 Nov '20

External Email - Use Caution Hello, I am using FreeSurfer 7.1.1 to run LGI and have done so successfully. I am now trying to quality check my data using tksurfer as described on the wiki tksurfer my_subject_id lh inflated -overlay lh.pial_lgi However the LGI overlay is not covering the entirety of the inflated brain.
