Re: [Freesurfer] Compare individual to a group

External Email - Use Caution Douglas, Just as I mentioned in the initial email, subjects in the healthy group have different ages. Because average cortical thickness is believed to be declined as the age gets older, I want to "normalize" the group by multiplying each subject's thickness with an age-dependent scalar (pre-calculated constant). Suppose I take age 30 as the "standard" age, then subjects with ages greater than 30 will have scalars greater than 1 (depend on age); subjects with ages smaller than 30 will have scalars less than 1. In this way, all subjects in the group looks like to be at the same age (30). Of course, I also suspect that there is no need to do the above mentioned normalization if I use mri_glmfit. But my initial intention was using non-linear scalars, and mri_glmft can only use linear fit. Please give me your opinion. Thank you! Xiao

External Email - Use Caution Hi Douglas, Thank you very much! Could you please help me with more detailed information? 1) Should I use "Variables age" or "Variables age weight" in the fsgd file? If I can use either of them, which one is better? 2) For the contrast file, the content "1 -1 0" you mentioned, it corresponds to the "Variables age" fsgd file, correct? 3) If I use the "Variables age weight" fsgd file, what will be the content of the contrast file? Is it "1 -1 0 0"? Thank you again! Xiao

Re: [Freesurfer] freesurfer 7.0.0 in a virtual machine...

External Email - Use Caution Hello Gonzalo, If you don’t mind using Ubuntu 18 as the OS in the virtual machine, then we already have a virtual machine you can run with virtualbox that is close to what you want.   It has the previous version 7 beta 1 release of freesurfer (and also freesurfer 6).  You could start with this VM and update to the 7.0.0 release. The Ubuntu VM is here,https://surfer.nmr.mgh.harvard.edu/fswiki/VM_67 The 7.0.0 release archive is here,freesurfer-linux-centos7_x86_64-7.0.0.tar.gz Once you bring up the VM (instructions on the web site for doing it on MacOS and Windows), then you could:1) delete everything under /usr/local/freesurfer/7.0.0.0-1b12) rename that subdir from 7.0.0.0-1b1 to 7.0.03) untar the 7.0.0 release archive under the new 7.0.0 archive4) change the bashrc file to use 7.0.0 wherever it says 7.0.0-b1 You could also run the Ubuntu VM on linux - the instructions would be mostly the same as listed for the Mac or Windows. If you want to run some other OS besides Ubuntu and create your own VM from scratch, then you could use osboxes.org to get the base image to create a VM from. - R.

External Email - Use Caution Hello again, I successfully installed FreeSurfer 7 on Centos 8 and it works smoothly. my concern is regarding the CUDA compatibility, in recon-all help I found the (-use-gpu) flag is present but when I tried to use it, I got error for unrecognized flag. Is there a way to take the part of code concerning CUDA from freesurfer 6 and include it in version 7 as it save a huge amount of time best regards Mina Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10

Compare individual to a group
by Xiaojiang Yang 07 May '20

07 May '20

External Email - Use Caution Dear FS experts, I have a group of healthy subjects. Given a new individual subject, I want to compare its cortical thickness to the healthy group so that I can find where the thickness is abnormal (thickening or thinning). I use fsaverage as the template subject to calculate mean and std of the healthy group. Since subjects in the healthy group have different ages, I do a "normalization" process to all the subjects in the group BEFORE calculating the mean and std. Thus the normalized healthy group can be regarded as all subjects having the same "standard" age. The normalization process is just multiplying some pre-obtained scale (varied by age, but not linearly ) to the file ?h.thickness.fwhm0.fsaverage.mgh of each subject that are already calculated by "recon-all --qcache" command. So the mean and std of the group are actually weighted in the sense of Freesurfer's recon-all results. My questions are: 1) If I do vertex-wise t-tests by simply comparing individual subject's thickness to the group using mris_calc but WITHOUT using mri_glmfit, can I still use mri_glmfit-sim to do multiple comparisons correction? If yes, how? 2) If the answer is no for the above question, how should I use mris_glmft to implement my above thoughts so that I can use use mri_glmfit-sim? Specifically, how can I use the weighted mean for the group? 3) Take a step back, if I consider the weight is linearly correlated with the age, how to design the fsdg and contrast file? Thank you very much! Xiao

New PETSurfer Questions
by Ferraro, Pilar 07 May '20

07 May '20

External Email - Use Caution Dear Freesurfer experts, As previously mentioned, we are currently trying to test the effects of different PVC corrections on metabolism estimation in a group of patients. We would like to also include MZ and MG methods in the analyses, comparing them to SGTM and no PVC. However, while both MG and MZ provide voxel-wise results, we would like to use them in ROI analyses in order to be able to compare their outputs with the ones obtained with SGTM and no PVC. Are there any procedures that you would recommend to do this?
