[Freesurfer] What exactly was wrong with DOSS in QDEC

Hello, I am dealing again with the old issue of using DOSS in QDEC. This option was removed. I cannot find any detailed explanations of what exactly was wrongly computed when selecting DOSS. I only find as explanation: that there may be a bug in the way that QDEC computes contrasts for DOSS

Re: [Freesurfer] Analyze format

Hi Pablo the mat file is an extension to analyze the specifies the direction cosines. Without it we are only guessing at the anatomical orientation of the image. Unless these images have some marker such as a vitamin E capsule how will you ever know if we got left/right correct? cheers

[Freesurfer] Analyze format

Dear FS experts,I am trying to run recon-all on data with analyze format. I am aware that this is not the best format, however I do not have DICOM or NIFTI original data as this is a very old data from University of North Carolina. When I run import the images with recon-all -i. I am getting the

[Freesurfer] A-P to P-A on GE 3T Discovery MR750

Hi Everyone, In order to introduce distortion correction methods in our DTI processing pipeline, I wanted to acquire B=0 with A-P to P-A phase encode directions, as recommended by topup tutorials. I talked to the MRI operators at our facility, and they were not able to find out how to flip

Re: [Freesurfer] long_mris_slopes error

Hi Carolina, probably you are not interested in the average thickness, so you can drop --do-avg . Also usually people decide between pc1 and spc. The stack is also not really necessary unless you want to look at it. Try to remove the trailing / at fsaverage and --sd $SUBJECTS_DIR that should

Hi Alan - It can't find the file. Check the error message, part of the path to the file is repeated twice. I suspect you typed that part in both dcmroot and dcmlist. a.y On Wed, 25 Feb 2015, Alan Francis wrote: Hi Anastasia: I have run trac-all  using the following command: trac-all

[Freesurfer] warping segmentations onto unprocessed brain

Hi freesurfers, I am hoping to warp an aparc+aseg.mgh file from a subject's freesurfer-processed image to a separate (unprocessed) T1 image on the same subject. I would like to use a purely intensity-based nonlinear volumetric registration to do this, to save time and complication. I understand I

Hey Bruce, Thanks for responding. I would actually prefer nonlinear. I did not mention it, but the aseg data that I have is on a distortion-corrected T1 image, whereas the unprocessed image I want to warp onto is the same scan but not corrected for distortion. The distortions are nonlinear. I was

Is there any reason you need it to be nonlinear? I would think bbregister and mri_vol2vol would do the trick Cheers Bruce On Feb 25, 2015, at 11:18 PM, David Grayson dgray...@ucdavis.edu wrote: Hi freesurfers, I am hoping to warp an aparc+aseg.mgh file from a subject's
