Dear Anastasia, Thanks for the suggestions. The new control point didn't help. Therefore I uploaded remaining images. It would be great if you could have a look again.

20 Dec '12

Hi everyone, does anyone on the FS mailing list have any good recommendations for litterature on anorexia nervosa / eating disorders / starvation and brain morphometry ? I am especially interested in any study using FreeSurfer software. Thank you very much in advance, - Jenny Mercolini

Deterministic global tractography
by Maia Kipman 20 Dec '12

20 Dec '12

Good Morning, I would like to run deterministic global tracktography on 2 tracts for which tract tracing techniques in animals have established white matter connections. However, these tracts are not part of the 18 segmented in TRACULA. Because of crossing fibers, deterministic global tractography is more appropriate for the analysis I am running than local tracktography or probabilistic tractography. If I have run freesurfer segmentation for this cohort is there a mechanism I can use to run deterministic global tractography in the subjects native DWI space between two regions segmented by freesurfer? Thanks!

tracula - posterior density just one-dimensional curve
by Andi Heckel 20 Dec '12

20 Dec '12

Dear Tracula team, I have noticed in a multisubject tracula analysis, that the posterior density in many if not all paths in the path.pd.nii.gz file is just a bright one-dimensional curve, rather than a true distribution. The path.map.nii.gz is empty. This is true for both flirt and bbreg registered versions in many subjects. Trac-all finished wiithout errors. So did Recon-all. Could it actually be a memory (RAM) problem ? We are running tracula on a cluster with only 2.5 GB per core. thx for any help and kind regards, andi

trouble with tracula preprocessing step
by s0675204 20 Dec '12

20 Dec '12

Hello I have one more problem. Some of the subjects completed step 1 (preprocessing) successfully according to the logs & there are no error messages. However, when I try to run the bedpost step on these subjects, I get an error message saying there is no data.nii.gz file in the dmrirc There is however a dwi.nii.gz file present Can you help me understand what happened here? Has something gone wrong? How can I fix it?

Fwd: tracula problem:poor forceps major tract
by bryon mueller 20 Dec '12

20 Dec '12

After processing dozens of subjects through tracula I have found some subjects with tracts that are one voxel along the entire tract, for example the forceps major. After reviewing the data I believe the bvecs files are pointing the correct direction, I believe the registration between the T1/freesurfer segmentation and DTI is reasonably good (registration was performed with bbr), at least the anat_brain_mask-vent.bbr and dtifit_FA are reasonable and cortex.bbr and lowb_brain seem reasonably well registered. The brain extraction does look poor in that a large chunk of posterior skull remains in the anat_brain_mask-vent.bbr image but the as the registrations, segmentations and parcellations look OK I believe this isn't the cause of my problems. I do see one issue: the registration between the dtifit_FA.bbr and fmajor_PP_avg33_mni_bbr_logprior_0 images. Sections of the logprior volume are entirely in the lateral ventricles of the DTI data. Please see attached jpg. This subject large lateral ventricles and I am wondering if such subjects can be run successfully in tracula. Much thanks for any suggestions.

Monte Carlo
by Susan Alice McLaughlin 20 Dec '12

Hi Doug, I am trying to run a Monte Carlo simulation on functional data constrained to a label. Looking at a previous post - https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2010-November/016290… - I see that your advice is to 1) constrain when running mri_glmfit, then 2) use mri_glmfit-sim rather than running mri_glmfit with the simulation options. I have done step 1, however when I try to mri_glmfit-sim, I receive a "command not found" message. I confess that I am running an old version of Freesurfer (v 1.133.2.5). Is this my problem? If so, will it be a problem if I run mri_glmfit with the simulation options? Thank you and happy holidays, Susan McLaughlin Doctoral Candidate SPACE Lab (Stimulus-Parametric Imaging of Auditory Cortex) Dept. of Speech and Hearing Sciences University of Washington

Hello, I would like to download and install the software described at http://surfer.nmr.mgh.harvard.edu/fswiki/GradientUnwarping Your email address is listed on this website. I cannot find a download link. We would like to use this with Freesurfer. Do you know where I can download this software from? Thank you, John John J.

Running SPM8
by Staples, Lindsay Katharine 20 Dec '12

20 Dec '12

Hi- Our Unix system was recently updated and I am now unable to use SPM 8 from /autofs/space/grover_001 or from /autofs/space/bert_002. I get the following message: Initialising SPM...Error using fileparts Too many output arguments. Error in cfg_util>local_initapps (line 1217) [p n e v] = fileparts(appcfgs{k}); Error in cfg_util (line 587) local_initapps; Error in spm_jobman (line 149) cfg_util('initcfg'); % This must be the first call to cfg_util Error in spm (line 344) spm_jobman('initcfg'); Any words of wisdom? Thanks! Lindsay
