error mris_anatomicalstats
by Linn Mittlestein 26 Mar '13

26 Mar '13

Dear Freesurfer experts, I have a question about trying to extract statistics from merged labels using mris_anatomical_stats. I have used the mri_annotation2label, and then the mri_merge label, however now when trying to do mris_anatomical stats, I get the error ; could not read input volume, eg Freesurfer cannot read the wm.mgz file. What step have I done wrong? Thank you very much, Kind Wishes, Linn

Pial error (over estimation)
by Charles Malpas 25 Mar '13

25 Mar '13

Dear Freesurfer experts, I am having a strange problem with a single brain. Freesurfer is over estimating the pial surface by a great deal. Two things are weird: (a) it occurs to the same brain scanned 6 months apart, and (b) it doesn't occur is 5.1 (I am using 5.2 now). I have attached some screen shots. Any help would be greatly appreciated!

advice in registering a binary mask to Freesurfer space.
by Joshua Lee 25 Mar '13

25 Mar '13

Hi All, I wanted to get peoples advice on the best method of registration/interpolation to use on a manually traced segmentation (and its structural) that is not in the same space and orientation as the structurals I started Freesurfer with (although they both originally came from the same image. I want to maintain the integrity of the manual traced binary mask through this registration and reslice. For a number of reasons, I do not want to take Freesurfers output to the space of the manual segmentation. What do people think is a good technique? Flirt nearest neighbor interpolation? Something different from Freesurfer? ANTs? - Josh

problem with registration in preprocessing

Hi Doug, I am running fsfast preprocessing on my data and I am getting an error on one of the runs.

Any idea how I can fix the error?

surf2vol
by Daniel Lumsden 25 Mar '13

25 Mar '13

Dear All Apologies for what I'm sure is a very basic question. I'm new to using freesurfer, and would like to generate cortical parcellations for running in probtrakx. I have followed the instructions from various sources and have managed to generate the parcellations from recon-all, extract the label files from the parcellation, then use mri_mergelabels and label2surf to generate the the .gii files needed for probtrakx. I'd like to be able to display the surface files for illustrative purposes, but I'm struggling to apply the surf2vol command. >From the terminal window I can see that the commands required are: surf2vol <surf> <refvol> <outvol> <convention> I presume that <surf> is the .gii file I'm trying to visualise, and <outvol> is to specify the name of the output volume the command will generate, but what should I be using as the <refvol>? I would be very grateful for any guidance. Please accept my apologies if I've missed a very obvious online explanation for this and thank you in advance. Dan Lumsden Clinical Research Fellow

-clean-* flags
by obregon＠nmr.mgh.harvard.edu 25 Mar '13

25 Mar '13

Hi, I was wondering if the -clean-* flags should only be used when you've performed manual edits on your volumes, or if they are also necessary when you re-process your subjects? For instance, let's say I edit the Talairach transform and run the entire recon-all process (using the -all flag) on a subject I had previously processed using the previous release of Freesurfer. If I had done no other manual edits on volumes such as brainmask.mgz, wm.mgz, etc., will these volumes be automatically overwritten when I run the latest version of recon-all, or do I need to specify the corresponding -clean-* flags in order for this to take place? Thanks, Gabriel

QDEC issues
by Tudor Popescu 25 Mar '13

25 Mar '13

Hello everyone, I created a qdec.table.dat for my design (a simple group analysis, with gender as categorical factor and age as continuous factor), and created a gender.levels file containing the values that are found in qdec.table.dat, spellt in exactly the same way (all files attached). However, when loading the file in QDEC, I get the error: *ERROR: Subject C01 has an invalid level 'controls' in the group column INFO: If 'group' is a discrete factor, then create a file named 'group.levels' containing the valid factor names one per line. Error loading the data table. * The strings under the fsid column (subject ID) correspond to those that I used after the –subjid xxx, in my previous call to recon-all (e.g. "C01, C02, M01, M02.."). The qdec.table.dat was created in Excel and saved as a tab-delimited txt file. Replacing the tabs with spaces/commas does not change the error message. What could be the problem? I also have a few more questions, if I may: - how much more accurate are the results of a QDEC analysis if an average subject is computed from the subjects of the sample, with make_average_subject, as opposed to using FS's default average subject, fsaverage? - the qdec.table.dat in the tutorial <http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/QdecGroupAnalysis>contains more than just "demographical information", for instance it contains the volumes of the left and right hippocampi; are these types of informations normally brought in from previous analyses (that may have been done in a package other than FS), or does one first have to obtain any such relevant predictors in FreeSurfer, before starting the QDEC analysis? - the QDEC tutorial seems to be for whole-brain analyses; the ROI analysis tutorial <http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROI>mentions nothing of QDEC, however; can ROI analyses not also be done in QDEC? - in the Group Analysis (non-QDEC) tutorial<http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysis>, the design matrix (Xg.dat) is in the form MembershipF| MembershipM|AgeF|AgeM, while the values in the contrast are said to correspond to the 4 parameters (intercept for F,M; slope for F,M). Either way, how can the contrast vector be interpreted to give the correlation between thickness and age? - in the same tutorial, why is the value 0 being given to the first two elements in the matrix, when it should only be given to nuisance variables? Many thanks in advance for any help! Tudor
