TRACULA tract path failure
by Arman Eshaghi 28 Nov '12

28 Nov '12

Dear all, I have difficulty sorting out the problem with some tracts in several subjects, tracts are incomplete or missing. As it has come up quite a few times on the list, for this sort of problem I have first set "reinit=1" and then increased control points to 7, and re-ran trac-all with "-prior" flag. This has worked for some tracts in several subjects, however there are a few subjects that still have this problem. It would be great if someone could let me know what else I might be able to do in order to correct missing/faulty tracts in my subjects. (The problem is not limited to a specific tract, it varies in different subjects) All the best, -Arman

Re: [Freesurfer] fieldsign-sess problem in retinotopy
by Zhou, Wei 28 Nov '12

Hi Doug, Thank you for reply. yes all 4 are in bold separately. I tried -run-wise with selxavg3-sess, but it failed with the following msg: Saving X matrix to /media/local_home/zhouw4/EM0220/analysis/retinotopy/SUBJ01/bold/rtopy.self.lh/pr001/Xtmp.mat Error using svd Input to SVD must not contain NaN or Inf. Error in cond (line 39) s = svd(A); Error in fast_selxavg3 (line 254) XCond = cond(XtX); I attach the mat file in the email. I am thinking that the error is similar as that I only put polar or eccen session in bold folder. Thank you for looking into it. Best Wei ________________ But all four runs into a single bold folder, then try running selxavg3-sess with the -run-wise option. This will create separate run analysis in the output directory. I have not tried it with retinotopy before, so get back to me if it fails. doug On 11/26/2012 05:53 PM, Zhou, Wei wrote: > Hi Doug, > I think I didnt explain clearly last time. > Here's the thing: > I have four runs: 2 eccen and 2 polars.

bad reconstructions

Hi, sorry I have an additional question; when reconstructed 9with edits), if the scan seemingly is worse off than before the edits were made; is there a "recon clean" command; that one can use that takes away all the edits and "starts from scratch? Thank you, Cathy

Problem Visualizing Hippocampal Subfield Segmentation in FreeView
by Juan Deliz 27 Nov '12

Re: [Freesurfer] Subgroup analysis
by MAHINDA YOGARAJAH 27 Nov '12

27 Nov '12

Hi Doug, Sorry the previous suggestion referred to a suggestion from Donald earlier in the thread as follows: "You might consider the contrast [0 1.5 .5 -.5 -1.5] across all 5 groups showing a linear effect of disease severity. The first column being controls." I will try that suggestion out, but I have also grouped all the patients and controls together in 1 group (as opposed to 5 different groups), and given that controls contains no endogenous factor giving them a covariate of 1, and then P1 a value of 2, P2 a value of 3, P3 a values of 4 and P4 a value of 5. There are good biological grounds to suspect that that the endogenous factor will increase linearly from P1 to P5, though the values 1 to 5 I have chosen are arbitrary. When I then run the GLM looking for correlation between dependent measure and this covariate, I see significant results in a similar (though more widespread) location compared to when I simply look for a difference between all controls and all patients (C v combined P1 to P4). Thus, I think (hope) the model has shown that Hopefully this is one valid way in which to show that it is the changes in the level of the endogenous factor contribute to the overall group differences (C v combined P1 to P4). Do you agree ? I will however try Donald's method as I also want to show that the interaction between age-thickness (that I see in C v combined P1 to P4) shows a linear effect across P1 to P4. Any suggestions for how I do that ? Thanks, M

Re: [Freesurfer] Subgroup analysis
by Mahinda Yogarajah 27 Nov '12

Hi, Thanks for the reference and explanation of the subtle statistical inferences. It was very useful. You are right in what i am trying to show (c- controls, p1 to p4 patients with varying levels of endogenous factor) which is that when patients are subdivided into levels of endogenous factor there is correlation with the changes seen in dependent variables compared to controls. So far, C v whole P gp - differences seen in plausible areas. C v P1 (greatest endo factor) subgp - no differences C v P4 subgp (lowest endo factor) - differences seen in plausible areas. Given that it is not valid to compare c v p1 and c v p4 (and p1 v p4 shows nothing) is the following valid - perhaps it is similar to what you proposed: Consider c and p1 to p4 as one group of subjects (theoretically the only difference between subjects being level of endogenous factor) but assign each subject a variable which represents level of endoenous factor (c - 1 p1 - 2 p3 - 4 p4 - 5) - then run glm looking for correlation between endogenous factor and dependent variable. Is this very different to what you suggested and any less valid ? Thanks. M

Regarding freesurfer segmentations for longitudinal data
by Prasanna M 27 Nov '12

27 Nov '12

Hi, I work in the area of longitudinal shape analysis, and have used the longitudinal OASIS data in the past. I was trying to find freesurfer segmentations of structures for the OASIS data, but could only find them for cross-sectional ones. I write to you to ask if you're aware of segmentations made available for the longitudinal OASIS data, specifically the hippocampus regions? If not, could you point me to the best way possible to segment these for the longitudinal OASIS data? Thanks, Prasanna -- -- Let there be peace on earth... And let it begin with me.

Hi Negar, sorry about the delay. The first thing to do is to look at the orig.mgz to see if there is anything funny going on, maybe most of the image is dark with one very bright spot or some other distortion.

Hi Doug, I think I didnt explain clearly last time. Here's the thing: I have four runs: 2 eccen and 2 polars. I followed the process http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastIndividualRetinotopyAnalysis and I hope to view the result of an individual session, e.g. one polar, which could display the activations with different angles. What should I do after all the analysis is done? Or I should run a retinotopy analysis different from the link above. Thank you in advance.
