Fwd: Is it possible to load flatmaps in freeview and draw ROI's on them?
by Devavrat Vartak PhD 09 Apr '20

09 Apr '20

External Email - Use Caution Hello Freesurfer developers, Thank you for developing Freesurfer! I am postdoc at UC Berkeley and I am using Freesurfer 6.0 to create flat maps on which I draw my ROI's. The flat maps/patches are created in TKSURFER. However, I typically use Freeview to visualise my volumes and inflated surfaces, overlay data etc. I am trying to open flatmap maps in freeview but I am not able to. I was wondering if it was possible to load flatmaps in freeview and draw ROI's on them and overlay my data? OS: MacBook OS Thank you.

Overlap of vertices in downsampled data
by Ersin Ersözlü 09 Apr '20

09 Apr '20

External Email - Use Caution Hi FreeSurfer experts, We calculated the differences with downsampled -fsaverage6- thickness data between our groups using 'PALM' on the vertex level and got .mgz files as overlays wit h log-p values for each contrast. Now, we would like to test the overlap. We computed a ratio of overlap through 'mri_compute_overlap' within log-p overlay files but it showed labels (-s option) such as unknown and white matter. Is there a way to differentiate vertices that are in cortical regions? And could this labeling be correct? Medical doctoral student University of Munich (LMU) Ersin Ersözlü

mri_convert input files
by Setiaman, N. 09 Apr '20

09 Apr '20

External Email - Use Caution Hi, I would like to convert my raw scans to nifty. The scans are made on a Philips scanner. I was able to retrieve most of them as DICOM files, but some of them are only available as PAR/REC. Does mri_convert also handle PAR/REC or can I only convert the DICOMS with this tool?

Tracula: tract length meaning
by Nazife Ayyıldız 08 Apr '20

08 Apr '20

External Email - Use Caution Dear Tracula experts, I want to compare two groups according to the length statistics from Tracula overall.stats outputs. I just need comprehensive explanations what "tract length" statistics mean and how they are derived and what their reliability is. I checked but I couldn't find detailed information. Are they suitable to use in group comparisons? If so, which one is more suitable to use: average, center, min or max length? I saw in some articles that they used average_length of a tract. If I want to use length statistics do you suggest taking any control variables? I read a message from Anastasia in the archive-list saying that we should be aware that these measures are in their individual DWI spaces. If I understood correctly, I shouldn't use them directly. Should I control the head sizes of the individuals then? How would you do if you wanted to do this kind of comparative analysis? I would really appreciate it if you answer. Thank you very much in advance! Best regards, Nazife -- -Nazife Ayyıldız-

whether freesurfer version 7 still support GPU
by Frank Robert 07 Apr '20

07 Apr '20

External Email - Use Caution Hello Freesurfer team I checked the freesurfer version 7.0. It says that " but for now you should know that some features are not present in v7 (QDEC, GPU-capability, and recon-all -make)." https://surfer.nmr.mgh.harvard.edu/fswiki/dev7beta1 But from the hardware setup, it still needs Graphics card: 3D graphics card with its own graphics memory & accelerated OpenGL drivers. This makes me confused. Since version 7 does not support GPU anymore, why does it still need the Graphic card? I found GPU may be helpful for some abnormal brain such as large ventricles. It may speed the calculation time. I do not know my observation is correct or not. Thanks Frank
