selxavg3 error : NaN in Xtmp.mat file
by Sid Kundu 07 Dec '12

07 Dec '12

Hi Doug, I created a new first level analysis along with new contrasts and event numbers for a group of subjects I had previously done analyses on. All but one of the subjects finished selxavg3 without error, but one subject gave the following error: Saving X matrix to /home/sidkundu/freesurfer/sessions/Heading-TTP/LMV2010_N19_Heading-TTP/bold/TTP-analysis-3/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 248) XCond = cond(XtX); >> ------------------------------------------ ERROR: fast_selxavg3() failed\n I looked at the generated Xtmp.mat file and it shows the design matrix X has all zeros in 2 columns, resulting in NaNs in the same columns for Xn, and corresponding NaNs in XtX. I'm wondering what would cause this or why it would only occur for only one subject. _________________________________ Sid Kundu Biomedical Engineering Boston University

regarding longitudinal segmentations
by Prasanna M 07 Dec '12

07 Dec '12

Hi, Do I work with aseg.fused.mgz or do I work with aparc files to get the most accurate segmentation of brain structures? I tried using freeview to look at segmentations. Is there a way to isolate mgz files of very specific structures. I mean, is there an inbuilt tool which can do that for me, or would I have to go image by image, and threshold to get, say the hippocampus? Thanks, Prasanna -- -- Let there be peace on earth... And let it begin with me.

fixed version of mri_glmfit and mri_glmfit-sim
by Knut J Bjuland 07 Dec '12

07 Dec '12

Hi I saw an updated version of mri_glmfit in ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/misc/linux-centos4_x86…. Should I update this file in my freesurfer installation. What do this fix? Is is not in the release notes? Along with mri_glmfir-sim from Doug Greve ftp site. Knut J

different MRI size
by Andrea Tateo 07 Dec '12

07 Dec '12

Hello FS experts, I would like to study MRI, by using FS, to extract binary images of hippocampi. My data images have sizes different from 256,256,256. Is there any FS procedure to generate images 256, 256, 256 from my data set? Does FS work only on images 256, 256, 256 ? Thank you very much Andrea

De-trending resting state data
by Chris McNorgan 06 Dec '12

06 Dec '12

I'm working with raw timeseries waveform data from a resting state dataset. There's one run per participant, so no between-run normalization is required. With Doug's help, I have mastered extracting the timeseries information from individual ROIs in surface space. The timeseries data is the product of the preproc-sess script, to which I additionally added the -inorm parameter to extract the mean timeseries for the entire volume. One concern I had was that correlations between timeseries from different ROIs might be artificially inflated by scanner drift. For example, if the overall signal increases or decreases as a function of time over the course of the run or fluctuates periodically, then for any two regions, their signals will go up or down together as a result. This should in turn make the timeseries from these two regions more correlated. I have no strong evidence that scanner drift is a particular problem in my dataset, but it seems likely enough in a 6 minute run that I want to mitigate the problem. I can't really put these data through selxavg, as I do not have a model to fit for resting state data, and in any case would like to work with the timeseries itself, rather than residuals or any other by-product of an HRF model. I was wondering if simply subtracting the global mean signal waveform from each ROI waveform would be a reasonable strategy for removing drift, or if there are any standalone commands that are called by some of the super-scripts that I can use without carrying out a first level analysis. Thanks, Chris
