mris_make_template needing .H file
by Sourena Soheilinezhad 19 Aug '12

19 Aug '12

Hi experts, I have tried this syntax for making a surface template: mris_make template ?h sphere subj1 subj2 subj3 my_template.tiff Output is an error saying "Could not read curvature file: ?h.infalted.H" But searching in the /surf directory for .H file, I have added "-infname white_avg" to the command and it seems to run smoothly. My question is, what is this .H file? Should I safely ignore the default search for inflated.H and keep on using white_avg.H instead? Also, the make_average_surface command gives the same "missing .H file" error but this time there is no -infname parameter to be manipulated. Thanks in advance, Sourena

How TE, TI and flip angle parameters affect the images and results?
by Daniel Ferreira 18 Aug '12

18 Aug '12

Dear all, We are designing a study based on clinical data. We want to work with a MPRAGE sequence but subjects have been given 4 different sets of parameters: - TR: 1900; TE: 4,38; TI: 1100; flip angle: 15 - TR: 1900; TE: 3,55; TI: 1100; flip angle: 15 - TR: 1900; TE: 3,39; TI: 900; flip angle: 9 - TR: 1900; TE: 3,39; TI: 900; flip angle: 15 I wonder how these differences could affect the images and thus the results. Can I combine all of them or at least some of them? Are they so different that I should just study them by separate? thank you very much on advance Daniel Ferreira

moving volumetric masks to surface labels within subject
by Alex Kell 17 Aug '12

17 Aug '12

hi freesurfers, i'm trying to move a volume from a subject's native anatomical space to that subject's surface space, and i'm running into some difficulty. we have binary masks in each subject's native anatomical space and we'd like to move these to be labels in that subject's surface space. there we'd edit them (either manually or with dilation and erosion) and extract some simple anatomical measures (like thickness) from that region in the surface space. to do this, i am using mri_vol2surf to get the volume in the subject's surface space, and then using mri_cor2label to convert this surface file to a label. the problem is that when i look at the label in the surface space, it is in clearly the wrong position -- even though when i look at the volumetric mask as an overlay in tksurfer it looks like it's in the position that it's supposed to be. for instance, see the attached. magenta is the volumetric mask overlay (in the correct position) and the blue-red circle is the label file (in the wrong position). my calls: mri_vol2surf --mov <volumetric_mask> --reg identity.dat --hemi rh --inflated --o <output_surf_file> mri_cor2label --i <output_surf_file> --id 1 --l ./<surf_label> --surf <subj> rh inflated "identity.dat" is a tkregister-style registration matrix where i just put ones on the diagonal and zeros everywhere else. i also tried mri_vol2surf where i used the --regheader flag. any thoughts? what's going on here? thanks in advance. alex

Separating Specific Areas from a .nii.gz file
by Sam Carpenter 17 Aug '12

17 Aug '12

Dear life savers, headache relievers and brain science dreamers, PROLOG: I'm trying to separate out some regions from a .nii.gz file. I start with a surface parcellation in .annot (Freesurfer land) that I convert to EXAMPLE.nii.gz using mri_aparc2aseg. THE GOAL: To get a .nii.gz file for each one of these regions. Using fslmaths, I threshold the EXAMPLE.nii.gz file above & below the intensity of that region & save as REGION_name.nii.gz. THE PROBLEM: This method is working for the majority of the regions. But many of the output REGION_name.nii.gz files are completely empty. They are there in the original EXAMPLE.nii.gz but are lost in the thresholding some(how/where). THE SOLUTION: Your kind reply... Thanks very much. -Sam

trac-all -path unable to open merged_ph1samples.nii.gz
by Knut J Bjuland 17 Aug '12

17 Aug '12

The Tracula script has been modifed and adopted to a local cluster. I am now able to run trac-all -prep, but trac-all bails out when I am running trac-all -bedp. Is there any work around since I am using FSL 4.1.9 with Fressurfer 5.1 I am not able to see what went wrong when I am running trac-all -bedp., but when I ran trac-all -path I get this error niiRead(): error opening file merged_ph1samples.nii.gz. Should I adjust the patch I have used to get around this error or should I run bedpostx ro another command before running trac-all -path? Will I be able to use Tracula from Freesurfer 5.2 with recon-all data used with Freesurfer 5.1?

Error Talairach registration
by Rajagopalan, Venkateswaran 16 Aug '12

16 Aug '12

Hi All, When I ran recon-all -autorecon1 in one of my subject I encountered the following error ERROR: talairach_afd: Talairach Transform: transforms/talairach.xfm ***FAILED*** (p=0.0000, pval=0.0000 < threshold=0.0050) Manual Talairach alignment may be necessary, or include the -notal-check flag to skip this test, making sure the -notal-check flag follows -all or -autorecon1 in the command string. so I ran the command as follows recon-all -notal-check -autorecon1 -subjid nonhyper_44 still I encounter the above error I don't know what I am doing wrong here.
