'std: :bad_alloc'
by Allison Rainford 02 Dec '16

02 Dec '16

Hi FreeSurfer team, I'm trying to create a base for 5 time points in freesurfer version 5.1 and have run into issues with my job submission exiting in error. This is the command I originally tried using: runFreeSurferSinglePBS -N huey.sw -r "-all -base P040_2yr5tp -tp P040b_v0 -tp P040_v6 -tp P040_v12 -tp P040_v18 -tp P040c" -S /project/freesurfer/CNADC_FS/PPA_v5.1.0/ P040_2yr5tp This resulted in the following error while starting global iteration: 2: Resolution: 0 S( 256 256 256 ) T( 256 256 256 ) Iteration(f): 1 -- diff. to prev. transform: 0.127011 Iteration(f): 2terminate called after throwing an instance of 'std::bad_alloc' what(): St9bad_alloc Because this appears to be a memory issue, I tried running it with a new memory parameter, using the following flag per a colleague's recommendation: runFreeSurferSinglePBS -m 4GB -N huey.sw -r "-all -base P040_2yr5tp -tp P040b_v0 -tp P040_v6 -tp P040_v12 -tp P040_v18 -tp P040c" -S /project/freesurfer/CNADC_FS/PPA_v5.1.0/ P040_2yr5tp I've also opened each of the 5 time points for this subject and cannot see anything wrong with any of the individual time points. Any help is greatly appreciated! Thank you, Allison Rainford Research Study Assistant Cognitive Neurology and Alzheimer's Disease Center Northwestern University 320 East Superior Street Searle 11-579 Chicago, Illinois 60611 Email: allison.rainford(a)northwestern.edu

Ubuntu or Centos?
by Brad Matushewski 02 Dec '16

02 Dec '16

I have had some issues with Ubuntu (installation stops before completing). I am currently trying to get a dual boot set up with Windows 10. Someone mentioned I should try Centos instead of Ubuntu? Thoughts?

TR : recon-all exited with ERRORS in Talairach
by jean-simon.boucher.1＠ens.etsmtl.ca 02 Dec '16

02 Dec '16

Hi Freesurfer Developpers, I'm trying to ''recon-all'' my MRI and I got an error in Talairach parts of the process. This is strange because I was able to complete the process entirely few weeks ago ... Here are the recon-all log files for the same subjects (the good one (few weeks ago) and the new one that I got now with ERROR). I've compared the 2 files and the only thing that is different is my platformversion (this is the linux version, right?). It has increased from 4.4.0.38 to 4.4.0.47. The only things that I have changed since the first time that I was able to perform the freesurfer process are: - Update on Linux - Installation of a new hard drive. Note here that I've tried to bypass (not using) the hard drive in my process. I've tried a lot of thing and one things that seem to be my problem is the Version of Perl (5.22.1) with my version of Freesurfer (5.3.0). (https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2016-November/048807…) Strangely, I haven't upgraded any of theses since the first time that I was able to run Freesurfer. Moreover, I don't have the access to change the version of perl (yes I've tried to change it for version 5.16) Do you have any idea what I'm doing wrong? Thanks a lot! Jean-Simon Boucher B. Ing.

Thanks Doug. Does that mean that a one group design? With a contrast of 1 0 (adjusting for one variable)?

PCA on PET / Thickness in Freesurfer
by Foo Keat Mak 01 Dec '16

01 Dec '16

Hi Freesurfer Team, For a given group, I want to look at the covariance patterns between thickness and PET. Within Freesurfer, what are some general workflow tips on how I could go about performing PCA (within modality) or joint ICA analyses looking at the covariance patterns across modalities? Is the -pca flag a good starting point? Any feedback is appreciated! Thanks a lot. Best Wishes, Elijah

Demeaning variables
by Rodrigo Gonzalez Huerta 01 Dec '16

01 Dec '16

Hi Freesurfers, For obtaining my undergraduate degree I'm performing a study using Freesurfer. I'm stuck with the centering (de-meaning) issue. I have two discrete variables, gender, and patient-control, and a continuous variable which is age. The age population range goes from 20 to 55 years and is paired between patients and controls. Patient's disease affects cortical thickness over time and every patient has been presenting the disease for 6 years (no more, no less). I've runned QDEC and mri_glmfit using DODS obtaining the same results, the problem is that when I demean the age (I used the grandmean) the results are very differente. If I don't demean some clusters survive the monte-carlo multiple comparisons correction (p<0.05), but, when I demean no cluster survive. I have this questions: 1. Since most of my subjects are in the range of 20-35 years and only a few have more than 35 years, it is correct to use the mean? Wouldn't be better to use the median or some other value? 2. This is maybe a silly question, but why should I care about the intercept? I know that demeaning doesn't change the slope, just the intercept, but I don't understand why I should care, I read in some publications that demeaning is not always necessary. Other questions: 1. Most of my subjects are women (around 80%, N=18), Does it have an advantage to remove the males to get rid of the gender variable?, or should I continue as I've been doing, controlling for the effect of gender. 2. Since I don't know if this disease is more aggressive when is developed at some stage of life, I mean, if young patients are less affected than older patients after six years of presenting it, it is correct to control the effect of age? (Entering the variable as a nuisance factor), or should I search for an interaction between age and the condition variable? I only care about differences in cortical thickness. Any suggestion is very welcome, thanks in advance for your answer. Rodrigo

DTI Multi band sequence?
by Martin Juneja 01 Dec '16

01 Dec '16

Hi, I was wondering if there is any way in FreeSurfer/FSL/MATLAB to determine whether the DTI data (in DICOM format) I have is multi-band sequence? I used dicominfo in MATLAB but couldn't find any information related to multi-band in the dicom header. Any help would be really appreciated.

Pegasus workflows?
by Heiland, Randy 01 Dec '16

01 Dec '16

Hi, Somewhat off-topic, but are there Freesurfer users on this list who might use the Pegasus WMS for executing workflows? If so, I’d like to hear about your use cases. I’m part of an NSF-funded project to incorporate data integrity and security assurances into Pegasus for scientific workflows. thanks, Randy
