Re: [Freesurfer] mri_vol2surf after recon-all

thanks, Doug. I am still extremely confused, however. *Am I meant to run recon-all first? *I was told in a previous email that I should do this first, however, I thought that Freesurfer takes the volumes and does a linear registration to MNI305 template, which would not work for my scans that are l

[Freesurfer] Nonlinear CVS registration into average brain for coordinates

Hi all, I have a data set of 14 subjects with intracranial (both cortical and subcortical) electrode implants, already recon'ed in Freesurfer, with an average brain + surface computed of these subjects. I would like to map each subject's electrode coordinates (a set of RAS points) into the aver

rename the file from "/Applications/freesurfer/license.txt" to "/Applications/freesurfer/.license" It should be backwards compatible but in this case it appears their is an issue. The error went away for me when I tested it, but please let me know if this doesnt work for you. -Zeke On 04/07/2

Hi there, I'm trying to install Freesurfer onto our Mac OS X 10.10.5. I was able to download the program and install it onto the two users on this computer. I am also able to open bert using freeview, open qdec, and start the recon-all for bert. However when I try to load bert using or , I ge

Hi Meng, here are some reasons for different looking images (and therefore different structural estimates): A Acquisition A1. Head Motion during acquisition: See e.g. http://reuter.mit.edu/publications/pid/reuter-motion14 http://reuter.mit.edu/publications/pid/tisdall15 A2. Hydration levels ht

Hi Laura, 1) you would need to model the 3 level variable differently, as 1,2,3 will be understood as continuous and that is not what you want. Instead you have two columns: one column for group 2, where all instances are binary (1 if group is 2, else 0), and one for group 3. Then the intercep

​Hi everyone, I am trying to extract regional cortical thickness but confused with the altered values for the same subject within two days. In our experiment, participants were scanned with the identical protocol in three times continuously: including baseline, 2 hours, 24 hours later. All T1s w

Dear FreeSurfers and LME experts, I've just started using the LME toolbox by Bernal-Rusiel et al (2012, 2013) in Matlab, apart from FreeSurfer. My experimental design includes one between-subjects factor (group with two levels, 24 vs 22 subjects), and two within-subjects (WS) factors (day with
