missing ROI when using mri_label2vol to transfer ic2.tri
by Leon 05 Sep '12

05 Sep '12

Hi, folks when I transferred the annotation file obtained using mri_make_face_parcellation based on ic2 (162 labels) to a volume file using mri_label2vol, I found that one ROI patch was missing in the volume file (see attached). I searched archives and the closest thread I could found is that somebody reported an ROI with the last index was missing in the mgz file after they were transferred from the annotation file to the volume file. Could someone help on this? If this happens to be a bug, is there any other strategy that will allow me to get a GM/WM ribbon without a hole on it? Many thanks in advance Leon

freesurfer tutorial data
by Dix.Meiberth＠ukb.uni-bonn.de 05 Sep '12

05 Sep '12

Dear sirs and madames, unfortunately I wasn't able to download the tutorial data for freesurfer. The download interrupted at 2 GB within the "bruckner_data_tutorial_subjs.tar.gz" I already did the recon_all process for 90 brains and wanted to improve my skills for the corrections. Is there any advise you can give to get the tutorial data? Best regards, Dix Meiberth (B.Sc. Neurowissenschaften) Funktionelle Bildgebung Klinik und Poliklinik für Psychiatrie und Psychotherapie Universitätsklinikum Bonn Sigmund-Freud-Strasse 25 53105 Bonn Tel. 0228-287-16366 Dix.Meiberth(a)ukb.uni-bonn.de

repeated measures ANOVA with two groups
by Shannon Kogachi 05 Sep '12

05 Sep '12

Hi, Is there a way to set up a repeated measures ANOVA and ANCOVA with two different groups (ex: study group v. controls) and each subject has more than two timepoints? Would it be possible to assign each Input in the fsgd file to two classes (ex: timepoint scan and group) or is there another way to set up the fsgd file and contrast matrices? I've already used qdec in freesurfer 5.1 to calculate rates of change and symmetrized percent changes between the timepoints (using long_mris_slopes) but now would like to perform a repeated measures test. Thank you! -Shannon K.

Cortical parcellations and probtrackx2 in diffusion space
by Alistair Perry 04 Sep '12

04 Sep '12

Hello freesurfer experts, I know this has been posted elsewhere with the original probtrackx. I am basically trying to create a surface file from the aseg+aparc.mgz cortical parcellation created when running recon-all. I wish to use this surface file as the seed reference file when performing probtrackx2. I have succeeded sucessfully in transforming the cortical parcellation into diffusion space, and have created a label file for it. However, I am having difficulty understanding converting the label file into ascii format, as required for probtrackx2. I am aware that you can convert a label file into ascii format using mri_convert, but you have to specify the lh.white surface file created when performing recon-all. This does not make sense to me for one this label file is not in diffusion space. Plus, why would I only specify one surface hemisphere when I have a label file that lists vertices across both hemispheres? In the end I am asking whether it is possible/and the best method in creating an ascii surface file of the whole cortical parcellation in diffusion space? Regards, Alistair

Hi freesurfer family, I am trying to create the inner skull boundary and ran: mri_watershed -atlas - surf -useSRAS mri.nii brain However, after it finished running it said it was saving "brain", but "brain" was an unknown file type. Am i supposed to specify that somewhere? Thanks in advance, m

error in long_mris_slopes command
by Shannon Kogachi 04 Sep '12

04 Sep '12

Hi Freesurfers, I've just tried to use the long_mris_slopes command on some longitudinal data. I've created my long.qdec.table.dat file. I've run this command before without any problems but I need to re-run it again. This time when I try to re-run it this error pops up: ERROR 1 : mris_label_calc intersect did not work? Is there any way to fix this? it also tells me the following: cp: target 'path/subjectID/lh.long.cortex.label' is not a directory Please let me know if there is any way to fix this. thank you!! -Shannon K.

how i can compute volume of a VOI
by Eustratios Karavasilis 03 Sep '12

03 Sep '12

Dear all, i am new Freesurfer user (Freesurfer 5.0 installed). I want to calculate the volume of a VOI that is not calculated from recon all. I ll decribe you the steps that were followed. Using tkmedit and tkmedit tools i created ROIs in many slices. Every ROI i saved it as label, then i merge all the labels using the mri_mergelabels. I am trying create a volume from this "final" label using mri_label2vol, using as label the new "final" label, as template volume the origin volume (orig.mgz) but i don't have the register.dat file. How i can create it? The above way is the appropriate way to calculate a VOI? Thank you in advance!

cortical volume and ortical jacobian_whitematter
by Knut J Bjuland 03 Sep '12

03 Sep '12

Hi,I have looked into cortical surface volume and cortical jacobian_whitematter. Can I use these measure a in similar way as cortical thickness? Do jacobian_whitematter represent the whitematter thickness in the cortex? How reliable are cortical volumes compared to cortical thickness?Best regardKnut J
