longitudinal stream: adding a time point
by Adam, Ruth 08 Oct '15

08 Oct '15

Dear all, We have run recon-all longitudinal stream on two time points and now have an additional time point we would like to integrate. Since edits and analysis were already done using the 2 time points template, we would like to avoid creation of a new template (by combining all time points) and instead register the third time point to the pre-existing template. What is the best way to do so? Is there a way to force recon-all to use a specific template? Many thanks! Best, ruthi

Freesurfer v 6.0???
by Ajay Kurani 08 Oct '15

Hello Freesurfer experts, I wanted to see if the nightly dev builds of freesurfer are v6.0 with the new hippocampal subfields or if that download is in another section? If so can you send me the proper download location? Also is CUDA support still at 5.0 with this version or is there any updates to the cuda support? Thanks for your help. Sincerely, Ajay

create label files

Dear Experts, How do I extract the cortical thickness of a region of interest (which showed a group difference in the Qdec between-group analysis) for all the subjects so as to correlate with other measures in SPSS? There is no .label file in the Qdec folder; which file shall I use or do I have to draw the ROI manually? Many thanks, Lena

wm.mgz ventricle white matter problem
by Anastasia Klimovich-Smith 08 Oct '15

08 Oct '15

Dear freesurfer experts, I have an issue with -autorecon2-wm stage results (freesurfer v.5.3.0). Sometimes the ventricles are not fully filled and the white matter is localized within the remaining gaps. After manually filling the gaps in the wm.mgz (following the wiki - Fixing Common Geometric Inaccuracies in White Matter Surfaces) and rerunning (-autorecon2-wm) I still have the wm surface following the ventricle holes, even though I can see they are filled on wm.mgz. I used freesurfer v.5.1.0 before and didn't have these issues. How would you recommend fixing this? Thanks a lot, Ana

tilted head
by Thục Trinh 08 Oct '15

08 Oct '15

Hi Freesurfer Experts, We are on the process of troubleshooting on all of our subjects and come across with the problem that we have not faced before. Here it is: We have several subjects that their heads were not in a perfectly straight line captured by using MRI. Does that affect to the segmentation of a recon, and more importantly somehow carry out some statistical values for further analysis (volume, cortical thickness)? As you can see, Axial view shows the head being tilted to the right. Sagital_lh and Sagital_rh images show how the white matter and gray matter segmentation are being bounded on the same slice 130 but in different hemisphere. Do we need to do something about it? If yes, how are we going to fix it? We are greatly appreciated to your patience and hopefully to get your response as soon as possible. Trinh
