freeSurfer make option is not compatible with pial refinement option
by Antonin Skoch 12 Feb '16

12 Feb '16

Dear FreeSurfer experts, I have some inquiries concerning the "make" option in recon-all: 1. It seems to me that the freeSurfer "make" option in recon-all (at least in 5.3.0 version) is not compatible with -FLAIRpial / -T2pial option. I made some manual edits which required rerun of autorecon2 and autorecon3. The "recon-all -make all" did not rerun pial refinement, which means that the resulting surfaces were generated completely without any pial refinement. Therefore, as I noticed that, I had to rerun recon-all -autorecon3 -FLAIRpial in all affected subjects. Are you aware of this bug/pitfall? I think that this is quite a problem since user need not notice this unexpected behavior which can seriously affect the final results. The user can believe he has surface refined, but instead they are not. I think that modification of recon-all.makefile could solve this problem. 2. I also found that there is no "make" option for local gyrification index. Would you consider also to implement that? 3. My last question is concerning the touch files. It seems that most of the "make" directives do not examine touch files, but the original (volume or surface) files. Therefore, it seems that most of the touch files are never used. What is the significance of touch files? 4. I also noticed some inconsistency in documentation: reconAllTable for 5.3 version does not contain -FLAIRpial / T2 pial step at all. https://surfer.nmr.mgh.harvard.edu/fswiki/ReconAllTableStableV5.3 They are documented only in dev version https://surfer.nmr.mgh.harvard.edu/fswiki/ReconAllDevTable but it does not correspond to 5.3.2 version - there seems to be difference in the position of -nuintensitycor step in the processing flow. Is there an actual table of reconstruction steps for 5.3.2 version? Regards, Antonin Skoch Institute for Clinical and Experimental Medicine Prague, Czech Republic

abnormal inflated surface
by Jasmin Alves 12 Feb '16

12 Feb '16

Hello freesurfer, I received this odd inflated surface image. I am not sure if this is something that can be fixed via a registration step or should be fixed in another step. Your input as to how to correct this image would be greatly appreciated. Also, I noticed that this participant's hippocampal volume is half the amount compared to the rest of my participants. Is it possible these two problems are related or am I possibly dealing with two separate issues? I have attached a screen shot of both problems. Thank you very much, Jasmin -- Jasmin Alves Predoctoral Student Medical Biology Graduate Program University of Southern California jalves(a)usc.edu

Freeview to mark only one specific area
by Luis Fernado Silva Castro de Araújo 12 Feb '16

12 Feb '16

Hello Freesurfer experts, I want either a 2D or 3D picture of one of my subjects image, but with only one colored area. For example, I would like to mark the lh_lateralorbitofrontal_area. It seems that the tool to visualize images in Freesurfer is freeview, however I can't find the label for the left hemisphere lateralorbitofrontal_area in the GUI. It is not listed in the Volumes tab with the aparc+aseg item ticked. I did not find information in your website, maybe I missed. Could you please provide a pointer towards the answer? Maybe I missed where it is taught at the documentation, a simple link would do. Thanks, luis
