by Mark Plantz 29 Jul '13

29 Jul '13

Is there another way to find the segmentation values?

Error "Cannot allocate memory"
by Annemarie Brandhofe 29 Jul '13

29 Jul '13

Dear freesurfer community, we are conducting cortical-thickness analysis using freesurfer-5.1.0 and have been experiencing some problems with the automatic recognition of the control points. For several subjects, we run the recon-all command and after about 40 hours of computations, we receive the error message “Excessive topologic defect encountered: could not allocate 171060256 edges for retessellation Cannot allocate memory”. After the occurrence of the error message, the computation is stopped. Below, we provide the details of our setup and the exact error message for one subject. Feel free to ask for more information. Thank you very much for your help! Yours sincerely, Annemarie $ bugr FREESURFER_HOME: /apps/prod/i486/freesurfer-5.1.0 Build stamp: freesurfer-Linux-centos4-stable-pub-v5.1.0 Debian version: 5.0.6 Kernel info: Linux 2.6.27.39-1-ql-beowulf i686 $ which freesurfer -> /apps/prod/i486/freesurfer-5.1.0/bin/freesurfer Used command: recon-all –autorecon2-cp –subjid IB34_mdeft.

Re: [Freesurfer] infant atlas segmentation

I guess the problem is that those regions should not be out of bounds. Maybe I need to create a new Lookup Table for the infant mri's? Is that possible to do?

displaying labels from old session onto new session
by Bianca van Kemenade 29 Jul '13

29 Jul '13

Hi Freesurfers, I have some participants of whom I obtained retinotopic polar angle data in a previous session, and scanned eccentricity data in a later session. I used the polar angle data to define V1-3, and would like to display these labels on the eccentricity session to help me define V3A. However, when I load my old V1-3 labels onto the inflated brain based on the new session the labels look very strange. I attached a screenshot of what is supposed to be lh dorsal V1, as you can see it is scattered all over the cortex. When I load the .nii based on the label into MRIcron, the ROI looks fine. Data from the newer session were coregistered to the older session, so that can't be the problem. I looked around on the wiki and found the command mri_label2label that seemed useful. However, this command needs acces to the 'surf' folders of both sessions. Due to a computer crash I only have the labels of the previous session, not the 'surf' folder. Is there a way to display my old labels onto the new session without needing access to 'surf'? Thanks, Bianca

Processing Multiple Subjects
by Michael Kranz 29 Jul '13

29 Jul '13

Hi all, If I process more subjects than the recommended amount given my number of cores and memory, will this affect the stats/surfaces or just slow the process down? I'm asking due to the sensitivity of workstations and also I seem to be getting slightly different stats sometimes when I re-submit to recon-all but haven't pin pointed the reason yet. Thanks, Mike

function that do the same step like qcache?
by fatma zribi 29 Jul '13

29 Jul '13

Dear Bruce, Would you mind tell me if there is a function of freesurfer that I can use to do the same step of qcache to smooth and interpolate in the fsaverage one subject with mri_surf2surf I can smooth only or align one subject with an average. thank you for you help. with best regards, Fatma

dPSD and ev duration
by Ella Hinton 28 Jul '13

28 Jul '13

Hi Quick question - why must the duration of the EVs be an integer multiple of the dPSD, which is also tied to the TR? I have event duration of 3 seconds, but would like to reduce my TR from 3 down to 2.5, but I can't seem to input the correct numbers for optseq to help me. thanks in advance Ella

A question about coordinates
by jh kim 28 Jul '13

28 Jul '13

Dear experts I have a simple question. To my knowledge, Freesurfer uses Talrairach coordinates. After doing 10000 permutations, I found that the resulting file *.sig.cluster.summary contained MNIX, MNIY, MNIZ coordinates. Are these coordinates in MNI space? Thank you in advance for your answer. Kim

Combining non accelerated and accelerated MRIs
by Stéphane Poulin 28 Jul '13

28 Jul '13

Dear Freesurfer experts I am using Freesurfer to process part of the ADNI 2 database which includes non accelerated and accelerated images. Images have different voxel sizes. Is there any litterature to guide me what should I do, ie combining or not these scans. Stephane
