Functional Connectivity in FreeSurfer
by Maedeh Khalilian 11 Nov '18

11 Nov '18

External Email - Use Caution Dear FreeSurfer experts, I have a general question, if i have a parcellation(an annotation file e.g aparc.annot which is the output of FreeSurfer) is FreeSurfer able to calculate the functional connectivity between the regions(parcels) using rs-fMRI data? I mean can I have a 68*68 matrix showing the functional connectivity between each pair of regions(parcels) at the end? I would be grateful if u could help me. best regards, Maedeh

We are actively working on it, but it's a time consuming process that involves many tracts. A few months, probably.

Please join us at Coastal Coding for Reproducible Neuroimaging: 10-16 Jan 2019 in Miami, FL

External Email - Use Caution ---------- Forwarded message --------- From: Angela Laird <alaird(a)fiu.edu> Date: Fri, Nov 9, 2018 at 3:42 PM Subject: Please join us at Coastal Coding for Reproducible Neuroimaging: 10-16 Jan 2019 in Miami, FL To: Dear Colleagues, Florida International University (FIU) is hosting a Miami workshop + code sprint in January 2019 called *Coastal Coding for Reproducible Neuroimaging* : *Jan 10-12: ReproNim + Nypipe 2.0 Workshop* The goals of this workshop are two-fold. First, to enable attendees to become familiar with best practices for reproducible analysis from ReproNim. Second, to learn how to create scalable and re-executable neuroimaging workflows with the upcoming Nipype 2.0 platform. This event is targeted towards novice neuroimaging users who meet the following requirements: (1) Working knowledge of Python 3; and (2) Familiarity with scripting in at least 1 neuroimaging package (e.g., AFNI, ANTS, FSL, FreeSurfer, SPM). Advanced users are welcome to learn about the changes and hack with Nipype developers. *Jan 14-16: NiMARE Code Sprint* NiMARE (Neuroimaging Meta-Analysis Research Environment) is a new Python package for performing analyses using neuroimaging meta-analytic data. Current tools for neuroimaging meta-analyses are spread out across several packages and languages. NiMARE aims to provide a standardized interface for a broad range of algorithms, along with interfaces to open meta-analytic resources like Neurosynth, NeuroVault, and brainspell. The three-day NiMARE coding sprint will occur after the Nipype workshop, with a one-day rest period between, in which participants can enjoy Miami. At the sprint, we’ll be working to design a standard for representing meta-analytic data, to add implementations for new tools, and to improve the documentation and test coverage of the existing codebase. Anyone interested in contributing to this new package is welcome to join. *Both the workshop and code sprint will be held at FIU’s scenic Biscayne Bay Campus*, conveniently located 17 miles from the Miami International Airport (MIA) or 19 miles from the Fort Lauderdale-Hollywood International Airport (FLL). Registration costs are $125 for one event or $200 for both events. Fees cover breakfast, lunch, snacks, and plenty of coffee. *Full details can be found at:* https://coastal-coding.github.io Please feel free to forward to your colleagues!

myelin and thickness pvr
by Damien MARIE 10 Nov '18

10 Nov '18

External Email - Use Caution Dear freesurfer experts, I would like to replicate an analysis I did with qdec but regressing out thickness at the vertex level. It’s a myelin group contrast with age and left average myelin as nuisance factors. I used the mri_glmfit command line generated during that qdec analysis and added the pvr flag but I got that error message: ERROR: dimension mismatch between X and contrast /home/damien/bin/freesurfer6/subjects/qdec/10nov/contrasts/lh-Avg-Intercept-R1projfrac0.5.mat X has 7 cols, C has 6 cols How can I solve that, should I modify the contrast.mat?

External Email - Use Caution Hello Freesurfer devs, Is there available any Desikian-Killiany and Destrieux atlas template or image downloadable with all brain labels of the atlas? I would to use this image to show my results in a lab meeting? I would need somethig similar that the lookup table used in the freeview. Cheers, -- *Miguel Ángel Rivas Fernández*

Multivariable linear regression with binary variables
by Worker, Amanda 09 Nov '18

09 Nov '18

External Email - Use Caution Hi, I am trying to run a multivariable GLM with mri_glmfit and I am currently setting up my fsgd file. I have 9 binary variables and 1 continuous variable. My understanding is that in the fsgd file, my "class" would be every possible combination of these binary variables - which is a lot (hundreds) and setting this up manually doesn't seem reasonable. Is this correct and if so could you recommend another way to run this analysis? Thanks, Amanda

External Email - Use Caution Hi Freesurfer experts, The cerebellar 7 and 17 networks parcellation cannot be downloaded. The link to cerebellar parcellation in SUIT is out of date too. so, if you can kindly share the cerebellar 17-network parcellation and their anatomy labels, I would be particularly grateful! Best wishes Fan 2018/11/08
