External Email - Use Caution Hello Safi, I would make a directory named /usr/local/freesurfer/7.0.0-1 and put the freesurfer 7 release under that directory. Then set FREESURFER_HOME to one of /usr/local/freesurfer/6.0.0-1/usr/local/freesurfer/7.0.0-0.1b1/usr/local/freesurfer/7.0.0-1 If your $HOME/.bashrc file sets FREESURFER_HOME such that when you start a new terminal, you see the output from the SetUpFreeSurfer script listing a FREESURFER_HOME=/usr/local/freesurfer/<something> that is not what you want, then change how FREESURFER_HOME is set in that startup file. - R.

Parcellation of files containing within subject summary measures
by Martin Gell 08 May '20

08 May '20

External Email - Use Caution Dear experts, I calculated vertex-wise standard deviation across multiple thickness (lh.thickness.fwhm10.fsaverage.mgh) and volume files (lh.volume.fwhm10.fsaverage.mgh) of one individual, calculated from scans at different time points. I used the freesurfer library for R to calculate the sd in thickness and volume between scans and saved the sd in each vertex as a new mgh file (one for thickness and one for volume). I now need to parcellate (calculate the mean value in each parcel) my new mgh files containing the vertex-wise sd using the Desikan-Killiany Atlas and Destrieux Atlas as definitions for the parcels. What is the best way to approach this? Thank you!

Hippocampal subfield tool for 6.0.0 data
by O'Shea,Andrew 08 May '20

External Email - Use Caution Hello, Would you be able to point me to the right version of the hippocampal subfield tool as described here: https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfieldsAndNucleiOfAm… The data have been processed in 6.0.0, but the stable pub version we have doesn't seem to have the segmentHA_T1.sh within it. I see 7.0.0 is out with these hippocampal tools but I know mixing versions is cautioned against. Where would I find the appropriate hippocampal tools for 6.0.0 data? Thanks! Andrew O'Shea, MSc.

recon-all-rms error < 2.00
by jiahui 07 May '20

07 May '20

External Email - Use Caution Hello FreeSurfer Developers, I run the recon-all -all command for aboout 10 hours.1. I want to accelerate, is there any way, such as how to achieve multi-core parallelism? Or is there another way to speed things up? 2. What are the quick ways to check image quality after running results? I've had a lot of subjects and it's not realistic to look at them manually one by one. 1) FreeSurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c

Re: [Freesurfer] Compare individual to a group

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!

Also include age as a covariate. Use DOSS instead of DODS. Then set your contrast to be 1 -1 0 and run mri_glmfit. I think that should properly account for age. On 5/7/2020 2:44 PM, Xiaojiang Yang wrote: 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
