Interpreting Covariate Paired Analysis Results
by PDMD SRALab 02 Jan '22

02 Jan '22

External Email - Use Caution We are using a paired analysis approach to study cortical thickness in a dataset with 2 timepoints (called pre-protocol and post-protocol). Regarding the mean cluster summary (contrast: [1 0]), we understand positive values to mean pre > post (thinning) and negative values to mean post > pre (thickening). The covariate results are more difficult to interpret. For instance, we’re interested in looking at the effects of age (contrast: [0 1]) on the cortical thickness results. In the age cluster summary, is it fair to interpret positive results as positive correlation (older subjects show more thickening) and negative results as inverse correlation (older subjects show more thinning) or is the interpretation more complex than this? We’re getting mainly negative cluster results for age so this interpretation may make sense, but we’d like more clarity. Thank you for your help.

Overlaying gfreat results to surface
by 刘宇琦 02 Jan '22

02 Jan '22

External Email - Use Caution Hi Freesurfer experts: I have a question on displaying results from FSL FEAT on surface reconstructed by freesurfer, especially results from higher-level analysis from gfeat directories. So I have successfully done recon-all on the participant's T1. I've also performed both first-level and higher-level analyses in FEAT. In overlaying first-level results from .feat directories, I did the following: reg-feat2anat --feat sub1_run1.feat --subject sub1 feat2surf --feat featdir Then, I overlaid the zstat1.mgh generated by the second command to surface, applying the anat2exf.register.dat file generated by the first command. It all worked fine. However, I'm not sure how to overlay zstat1.nii.gz from higher-level analyses (.gfeat/cope1.feat/stats/) to surface. According to online tutorials I found below, I could overay the zstat1.nii.gz file to surface, applying the anat2std.register.dat file from the first command above. But it didn't work. The figure on the left below shows results on 3D volume space and the figure on the right shows z values on surface using the method above. However, nothing showed up on surface and the values shown in the Config window are weird. My guess is that I have to first convert zstat1.nii.gz to zstat1.mgh and then apply registration, but I'm not exactly sure. Can anyone give any instructions? My other question is that the oneline tutorials on this issue use tkmedit and tkregister2 tools to inspect registration from feat to surface. However, none of these commands opens gui windows on my end. I'm using Ubuntu 18.04 on a Win10 and FreeSurfer 7. I guess these tools are replaced by Freeview but I don't know how to check feat2surf registration in Freeview. Can anyone provide some guidance? Thank you, Yuqi

Re: [Freesurfer] Questions about contrasts
by Laura Willers de Souza 02 Jan '22

02 Jan '22

External Email - Use Caution Dear Douglas, Again, thanks for the reply. Please check if I understand correctly: * First I do the contrast [0 0 -1 1] to test if there is an interaction between diagnosis and cortisol; if there is, I do DOSS [1 -1 0], if there isnt’t, I continue with DODS. * Having no interaction, I do the contrast [1 -1 0 0] to check if only the diagnosis changes cortical thickness regardless of cortisol. Did I interpret correctly? And how do I check if cortisol changes cortical thickness regardless of diagnosis (assuming there is no interaction)? Thanks again!

Sorry, but I don't think I explained myself correctly in the previous email. I want to analyze the difference in cortical thickness between two groups (CU and CI), adjusting for a covariate (cortisol CSF) and the interaction between them. So my model would be: cortical thickness ~ diagnosis + CSF cortisol + diagnosis*CSF cortisol Using the GLM DODS, the contrasts, according to the wiki example (https://secure-web.cisco.com/1TXDxaJK3TqwFMC6pi74Rk7x9g2fbD-V3AF6Mb-mJgTcED…<https://secure-web.cisco.com/1qbucUNWhNS-2uW6Lox1w2bMK8EUHU0lm2XC7ywMcgAz1o…>), would be: * To verify if only the diagnosis regression coefficient is significant (diagnosis changes cortical thickness regardless of cortisol): 1 -1 0 0 * To verify if the regression coefficient of the interaction between diagnosis and cortisol is significant (the two change cortical thickness dependently): 0 0 1 -1 * To verify if only the cortisol regression coefficient is significant (cortisol changes cortical thickness regardless of diagnosis): 0 0 0.5 0.5 Are these contrasts corret to represent the model we designed?
