mnc2nii input file problem
by Alexander Zaitsev 25 Jan '11

25 Jan '11

Hello: When I am trying to convert mnc file into nifti, the mnc2nii converter gives me an error $FREESURFER_HOME/mni/bin/mnc2nii fileName.mnc fileName.nii "Can't find input file fileName.mnc" Prepending a whole path to the file name does not help - same error message I am using FreeSurver 5.0.0 (MAC/Darwin/i686) build Any suggestions? Thank you, Alex Zaitsev

discrepant outputs from recon-all/mri_ca_normalize
by Tossi Ikuta 25 Jan '11

25 Jan '11

Hi everyone, I'm wondering whether there are multiple versions of recon-all v 1.313.2.6 (2010/08/04 15:50:56), and/or mri_ca_normalize stable5. I have been testing recon-all and compared our output against the sample processed-data in FS/TUtorial. I found that the output obtained was different from the sample, despite the fact that I ran recon-all with the same options as the sample outputs, on the same input files. recon-all -s bert -i /analysis/Tests/FSTest_Tossi/Samples2/buckner_data/tutorial_subjs/bert/mri/orig/001.mgz -i /analysis/Tests/FSTest_Tossi/Samples2/buckner_data/tutorial_subjs/bert/mri/orig/002.mgz -i /analysis/Tests/FSTest_Tossi/Samples2/buckner_data/tutorial_subjs/bert/mri/orig/003.mgz -all -debug -clean -norandomness -allowcoredump -time -subjid BertByTossi20110119A I performed a line-by-line comparison of the recon-all log between the sample and one from my run and found that our log differs from the sample (buckner_data/tutorial_subjs/bert/scripts/recon-all.log) at line 1034, where mri_ca_normalize runs the first path of smoothing (with sigma=0.200). Whereas the sample has 38 recursions, my run had 18 recursions for this section. The outputs hereafter differed from each other. I used the same version as the sample was processed, recon-all: v 1.313.2.6 (2010/08/04 15:50:56), and mri_ca_normalize: stable5. Not to mention, the input files are identical. Also, I ran the exact same line of the command more than three times, and obtained the exact same result. Therefore, I believe this is not due to any randomization introduced (if any) in normalization/smoothing. I used an x86_64 processor, the same as the sample. Thus, I do not believe this is due to any floating point resolution difference between architectures, either. The only possible reason I can think of that might account for the discrepancy is that there are multiple versions or compiles "stable5" mri_ca_normalize. I obtained the sample input and result from; ftp://surfer.nmr.mgh.harvard.edu/pub/data/bert.recon.tgz Our download md5sum matches the one posted. Here's a list of input files; $ls -l /analysis/Tests/FSTest_Tossi/Samples2/buckner_data/tutorial_subjs/bert/mri/orig/ total 17776 -rw-rw-r-- 1 tossi mrilab 5996899 2010-08-09 13:01 001.mgz -rw-rw-r-- 1 tossi mrilab 6077242 2010-08-09 13:01 002.mgz -rw-rw-r-- 1 tossi mrilab 6083164 2010-08-09 13:01 003.mgz Thank you very much in advance.

Bbregister for fsl tractography
by Lena Palaniyappan 25 Jan '11

25 Jan '11

Dear Doug & others The FSL page on fa to freesurfer registration ( http://www.fmrib.ox.ac.uk/fsl/fdt/fdt_surface.html) contain info that uses tkregister2. To determine freesurfer_to_fa space registration file, do we need to go through the freesurfer_to_struc and then struc_to_fa rooutine given in fsl pages.? I wonder if the registration can be done using the bbregister currently. If that is the case how to get the fsl-type registration file? tkregister2 had an option for this but it is not working with bbregister Cheers Lena _______________________________________________________ Lena Palaniyappan Clinical Lecturer & Honorary StR | Division of Psychiatry ( University of Nottingham) South Block 'A' floor| Queens Medical Centre | Nottingham | NG7 2UH This message and any attachment are intended solely for the addressee and may contain confidential information.

Which surface to mesh_vertex_nearest
by Gabriele Arnulfo 25 Jan '11

25 Jan '11

Hi again, looking in previous emails in the list i found that the best way to find the nearest vertex number to a certain point is by using the matlab script mesh_vertex_nearest. So far I've used it with input parameters: the vertices read through read_surf(rh_pial) and a matrix of Cartesian Coordinates. In this context I'd like to know which surface is the right choice, if there should be a choice. I've inserted either the pial and inflated surface having different result (vertex index) for the same point (RAS xyz). Cheers, g. -- In a world without wall, how needs WINDOWS??

In our last imaging genetic study (Cerasa et al., Dysbindin C-A-T haplotype is associated with thicker medial orbitofrontal cortex in healthy population. Neuroimage 2011 in press) we showed similar findings between Freesurfer and VBM analyses. ----- Original Message ----- From: Douglas N Greve To: Ritobrato Datta <ridatta(a)mail.med.upenn.edu> Cc: freesurfer <freesurfer(a)nmr.mgh.harvard.edu> Sent: Tue, 25 Jan 2011 10:43:37 -0500 Subject: Re: [Freesurfer] freesurfer and VBM Try looking at Voets, et al, 2008, in Neuroimage vol 43, pg 665-675. doug Ritobrato Datta wrote: > Hello All, > > Are there any papers comparing freesurfer to VBM ? > > Can anyone point me to them ? > > Thanks > > Ri > _______________________________________________ > Freesurfer mailing list > Freesurfer(a)nmr.mgh.harvard.edu > https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer > > > -- Douglas N.
