Problems with QDEC
by Vikas Bandalli 05 Aug '16

05 Aug '16

Dear Freesurfers, Sorry if the question sounds too basic. 1. I am running an analysis on qdec with paired groups - normal and patients, To control for IntraCranialVolume(ICV),I am adding it as an 'nuisance factor',Is it correct? The suggested mode to add ICV to the tabled was to *demean* the ICV. But when I subtract the mean values from individual subject ICV values,I noticed that some of the subjects have a negative demeaned ICV value. My question is - How should I proceed to include the data,ignore the negative sign(because I thought a negative ICV makes no sense) and just keep the values or retain the numbers with the sign. Please correct me if I am going wrong in any of the steps. However,I ran two analysis - one with the sign retained and other with sign removed ,I noticed that both have very different results. 2. If I want to see the effect due to lithium within the patient group (Between patients with and without psychosis) how should I design the matrix in GUI. I designed the following format Fixed factor :- Diagnosis - Psychotic-pt Non-Psychotic-pt Co-variate :- Lithium use :- 1 - lithium user 0 - non user Nuisance factor :- ICV Is this design correct? If not how should I construct it ? Also what query would contain the result for anticipated question My intention is to control for Diagnosis and then see effect/change due to lithium use. Thank you very much -- Vikas B. R. Medical student Bangalore Medical College and Research Institute (BMCRI), Bangalore,India, Ph : +918904286825

I can be understanding how TRACULA tracts white matter pathways. At each position (in training subjects, not in new subjects of my data) probability that next goes for which direction to every labels in the aparc+aseg (not with setting a certain ROI) is computed with use of training subjects. The prior probabilities are made from training subjects (your publication in 2011) and they are based on manual labeling (the manual labeling tracts are referred to Wakana et al. 2007). Then when white matter pathways are reconstructed in my subjects, TRACULA computes anatomical priors in each subjects in my data in pre-processing and probability distributions from anatomical priors and by fitting ball-and-stick model. Is this comprehension ok?

Spearman correlation in FreeSurfer
by martina.papmeyer＠puk.unibe.ch 05 Aug '16

05 Aug '16

Dear FS experts I would like to examine associations between cortical thickness and sum scores of a scale (ordinal scale). Accordingly, I would need to conduct Spearman rather than Pearson correlation analyses. I found the following post to this email list, indicating that the GLM model in FS is basically a generalization of Pearson: https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2009-January/009320.h… Since the post is from 2009, I would kindly like to ask if there is currently any way to conduct a Spearman correlation based analysis in FS or if there will be a way in the near future? Thank you very much for your kind help!

Re: [Freesurfer] How does Optseq2 arrange order of conditions?
by 連志浩 05 Aug '16

05 Aug '16

Dear Douglas, Thanks for your explanation. These information are helpful to me. >I'm not sure what you mean. How can it be a delay if it is after the trial is over? I’m sorry for I didn’t describe my second question well. I think I can take another situation to describe my question. If I have a experiment that present stimulus until participants response, and I know the average RT of this experiment is 1500 ms after pilot test. In this situation, should I +/- the duration of jitter/null condition in terms of the duration of each stimulus? For example, if a part of sequence Optseq2 output is “ Con1 Null(500 ms) Con2 Null(1500 ms)”, and one of participants takes 1000 ms to response for Con1. Should I add 500 ms to the first Null? or I don’t need to anything? Thanks for your reading. Best Regards, Chih-Hao

Error using LGI script despite making suggested changes to Matlab script.
by Sam Mathias 05 Aug '16

05 Aug '16

Dear all, I'm running into the following error when running "recon-all -s <subj-id> -lgi" using the latest version of FreeSurfer and Matlab R2016a: ERROR: make_roi_paths did not complete successfully! It seems like this is a common issue when using more recent versions of Matlab, so I editted the script as documented here: http://freesurfer.net/fswiki/ReleaseNotes?highlight=%28%28LGI%29%29 However, this did not fix my problem and I get the exact same error message. Any ideas? -- Samuel R.

recent problems with hippocampal subfield and brainstem modules
by Iglesias, Eugenio 05 Aug '16

05 Aug '16

Dear users, Many of you have recently experienced problems with the hippocampal subfield and brainstem substructure segmentation modules. These modules have been broken in the dev version for a couple of weeks. All the problems have now been fixed internally. The updates will be incorporated to the dev version on the website as soon as possible. So, if your subfield module is not working, just wait for a few days (I would say late next week, to be on the safe side), and try downloading the dev version again. On a happier note, we have added some new features to the modules: 1. They can now segment high resolution T1s that have been processed with recon-all -cm 2. There is now a longitudinal version of the hippocampal subfield segmentation module: https://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalHippocampalSubfields based on our recent Neuroimage paper: “Bayesian longitudinal segmentation of hippocampal substructures in brain MRI using subject-specific atlases” Apologies to everyone for the inconvenience, and special thanks to our developer Zeke Kaufman for all the work.

Poor automatic segmentation of the cerebellum
by Sam Mathias 04 Aug '16

04 Aug '16

Dear list, I'm interested in measuring cerebellar volumes using freesurfer. However, the automatic segmentation (aseg) seems to be doing a poor job of capturing the whole structure for many subjects. Specifically, it is chopping off the bottom of the cerebellum. Here is an example: https://drive.google.com/open?id=0B68CY3v4cg7tS0hSNkVVMWNiZV8xYWR2eTJQQlhFe… The issue seems to be when the cerebellum is very close to the bottom of the image, as is the case in many of our scans. Has anyone encountered similar issues with cerebellum segmentation, and if so, have any advice about how to improve it? Many thanks, -- Samuel R.

ROIs defined in MNI space and vol2surf
by Funk, Quentin 04 Aug '16

All, I have a question regarding the required registration file in mri_vol2surf. I have some spherical ROI's in MNI space produced via 3dUndump--they're volume files that show up in the correct places when loaded in with an MNI standard subject such as fsaverage. I also have some patients scans. I'd really like to compute cortical thickness for these ROI's on my patient scans, so I attempt to follow the instructions at ( https://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness ), but these instructions assume that the ROI is in the native space--which produces no problems until the step : cd $SUBJECTS_DIR/fsaverage/surf mri_vol2surf \ --mov /path/to/ROI5.nii \ --reg TT_avg152T1_to_fsaverage.dat \ --projdist-max 0 1 0.1 \ --interp nearest \ --hemi lh \ --out lh.fsaverage.ROI5.mgh \ --reshape My question is then three parts: (1) Why does vol2surf require a registration file? Shouldn't it be possible to do it as a straight conversion of data types if I know that my surface is registered to the file that I want? Perhaps naive, my first intuition was to construct a TT.dat that was the identity matrix, but this fails, with the response listed in (2). (2) How can I do this without shifting my data? If I follow the instructions, when the surface is overlayed on fsaverage's lh.pial, the entire surface is included in the overlay. (3) What exactly do the numbers mean in the registration file TT.dat (as in the instructions on the website)? The 4x4 matrix is clear, and the first two numbers appear to have something to do with Voxel resolution, but I'm unable to find documentation that explains the notation in the output.

mri_label2label holes
by Fred Dick 04 Aug '16

Dear Doug et al I was doing some cross-subject label morphing over a bunch of subjects (a big continuous patch of vertices) and was having problems with quite a number of 'missing' vertices in the morphed label. I saw Doug's previous response to this on the message board that there was a dev binary of label2label - I downloaded and tried but had a bunch of dependency/lib errors (I'm running OSX). Is there a new version I should be looking at? Thanks as always! best Fred
