How to obtain stats on custom anatomical ROI in freeview/freesurfer
by Lucette Cysique 27 May '14

27 May '14

Dear Ruopeng and colleagues, I am interested in following same tracing protocol for the amygdala as in "Neuroimage. 2012 April 2; 60(2): 1226–1235: "A reliable protocol for the manual segmentation of the human amygdala and its subregions using ultra-high resolution MRI” I would like as they did use freeview because it has some versatility and resolution that other programs do not have. I have however one issue Once I have created my ROI in freeview it ends up being by default a .label file. I create my ROI using ROIs and edit ROI tools and simply save it. I have tried to use “mri_label2vol” to get my ROI file (e.g., right_amygdala.label) into a volume file from which I thought I could then compute stats using “mri_segstats” But it does not work, as it seems that the initial .label file does not have the current format? Or required info? My command line output that it cannot read my .label file Thanks for your assistance Lucette

High Intensity Spots and Surfacing Issues
by Jonathan Holt 27 May '14

27 May '14

Hi all, this is a recurring issue that I'm hoping I can find a solution to. Pictured is a brain with a particularly high intensity area that seems to defy surfacing. Is there a way to work around this? See attached image

Registration and Surface Flattening
by Caka 27 May '14

27 May '14

Thank you Bruce, I convert the fsaverage flat map into a ascii file, using: mris_convert -p lh.cortex.patch.flat lh.cortex.patch.flat.asc. Now I need to read these two files. (1) I used read_patch.m to read lh.cortex.patch.flat. But an error came out, it said ‘ Error using ==> read_patch at 28, could not open file …’. (2) I couldn’t find a read_patch_asc.m script in Freesurfer, as is suggested in https://www.mail-archive.com/freesurfer%40nmr.mgh.harvard.edu/msg35813.html (3) I found a read_asc.m instead, but when I used it to read the lh.cortex.patch.flat.asc, an error occurred: ‘Error using ==> fgets, Invalid file identifier. Use open to generate a valid file identifier’. Could you please give me some advices?Thank you very much! Best regards, Qiongmin ————————————————Original email--------------------------------------- Hi Qiongmin 1. I think this is a bug in the open GL code that is outside of our control. We will try to track it down 2. The flat maps aren't really any different than say the inflated fsaverage surface. If you can generate group (or individual maps) in fsaverage space you can display them on the flat maps. 3. The index of each vertex in the flattened space is stored in the patch files so you can always look up what vertex it was on inflated, sphere, etc... cheers Bruce On Mon, 26 May 2014, Caka wrote: > Dear Bruce, Doug and all, > Thanks for your suggestion, it helped a lot. > > (1) I load the fsaverage surface (lh.inflated) in tksurfer, and then load > the fsaverage patch (lh.cortex.patch.flat).

Re: [Freesurfer] WG: WG: [Fwd: WG: missing temporal lobes]
by Bruce Fischl 27 May '14

Hi Kristina can you please post to the list so others can answer? If you add control points to the temporal WM where you are missing gm it should recover most if not all of it. Hippocampus is not neocortical and isn't supposed to be included. The surfaces are somewhat arbitrary there, and excluded from all subsequent calculations (like total cortical area/volume) cheers Bruce On Tue, 27 May 2014, Mayer Kristina wrote: > Dear Bruce > How can I get the Hippocampus and the missing parts of GM of the temporal lobe into the PIAL (sufrace mask)?

Re: [Freesurfer] Registration and Surface Flattening
by Caka 26 May '14

26 May '14

Dear Bruce, Doug and all, Thanks for your suggestion, it helped a lot. (1) I load the fsaverage surface (lh.inflated) in tksurfer, and then load the fsaverage patch (lh.cortex.patch.flat). The flat map was shown for several seconds, and then an error occurred and tksurfer was shut down. The terminal said: ‘tksurfer.bin:tnl/t_vertex.c:407: update_input_ptrs: Assertion ‘a[j].inputstride == vptr-> stride’ failed. Abort(core dumped)’. Could you give me some advice? I use a 'CentOS release 6.2' system. The freesurfer is ‘freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0’. (2) Indeed, I want to flatten all cortical thickness surfaces of 140 subjects onto the ‘lh.cortex.patch.flat’ of fsaverage. I just don’t understand your idea how to do this. After I load ‘lh.cortex.patch.flat’ of fsaverage, the tksurfer only shows this flat map (now it lasted for several seconds and crashed), so how can I ' load whatever overlay you want in the same way you would on the inflated surface’? Does it mean that I load the individual flat map on the individual inflated surface? But I haven’t got the individual flat map yet. (3) I am wondering if there are some table recording the transformation relationships between the fsaverage surface vertices and the flat map vertices? If so, then I think all I need to do is extracting the cortical thickness value of every vertex in individual inflated surface, and then putting into the corresponding vertex in the flat map. Thank you very much! Best regards, Qiongmin ------------------------------------------------------------------------------------------------------------------------------------------------- Load the fsaverage surface in tksurfer (say lh.inflated) then load the patch we distribute with fsaverage (I think it's called something like lh.cortex.patch.flat) with file->load patch.

modeling multiple scalars in F-contrasts
by L. Schweren 26 May '14

26 May '14

Dear Freesurfer experts, I am modelling multiple covariates (age, SES, nr of symptoms and nr of symptoms2) in one subject group. For the quadratic term I added a column in the fsgd-file. I want to visualize the effect of nr of symptoms, either their linear or their quadratic effects. I therefore made two contrasts: The effect of symptoms: 0 0 1 0 And the effect of symptoms2: 0 0 0 1 I would like to model these two effects together in one contrast (to get the results of both contrasts overlaid on top of each other, but in one mgh file). I tried the following contrast: 0 0 1 0 0 0 0 1 But the result is very different from the two individual contrasts. I get large (non-overlapping) clusters of significant effect in the two separate contrasts, but with the combined contrasts I get none. In the examples I found online for F-contrasts, they always add up to zero, as they are comparisons between groups. What would be the appropriate contrast if I want to visualize all regions with EITHER a linear OR a quadratic effect of symptoms? Thank you very much for your help! Best wishes, Lizanne

papers on reliability of volume of indivdual cortical parcellation regions
by Mehul Sampat 26 May '14

26 May '14

Hi Folks, I was able to find a number of papers looking at the reliability of cortical thickness of individual regions (ex: https://surfer.nmr.mgh.harvard.edu/pub/articles/reliability_wonderlick.pdf) I was wondering if there are any papers that have looked at the reliability of the volumes of the individual cortical parcellation regions ? Thanks Mehul

Thanks Douglas. We tried that . . . The registration matrix that we need is not created. Here is the output log file (attached). I am a bit new to this so I am hoping it has the information you need. After taking a quick glance at the log file, we noticed there are errors in the log file. Step by step, this is what we did after we ran recon-all: Reg-feat2anat ‹feat OurFeatDirectory.feat ‹subject P209 When we open the folder experiment.feat/reg/freesurfer, there is no anat2exf.register.dat file. However, there is a file called: anat2exf.register.dat.init.

finding cluster peak vertices
by Milde, Christopher 23 May '14

23 May '14

Dear Freesurfers, Is there a way to smooth already preprocessed functional images* (FEAT, FSL), which I coregistered to the reconstructed surfaces (reg feat2anat), on the cortical surface? Furthermore, I would be interested in finding the cluster peak vertex after smoothing the EPI on the reconstructed surface. I know that Hagler et al 2006 talked about a "vertex search method" to find the maximally activated vertex on the surface. Kindly regards, Christopher *the FEAT preprocessed and 1st level statistics FEATs are not smoothed to avoid blurring across attached gyri

WG: [Fwd: WG: missing temporal lobes]
by Mayer Kristina 23 May '14

23 May '14

Dear Bruce My dataset is very young (around 2 years of age), I suppose the contrast and size is just different from the default-template of freesurfer. Is there a way to exchange the template (I am thinking of a probabilistic map) without creating an own atlas first? Attached you find screenshots of my work and the recon-log of the same subject. I first run all recon-all steps. Then I added CP where WM was missing. I also added CP in GM region where lost of GM was missing (temporal lobe) to get the pial right. Then I tried to remove the WM which came out too much, for I placed CP in GM regions. Is there another way for it?
