Re: [Freesurfer] How to threshold an input mutli-volume?
Thank you in advance for your help. We installed the freesurfer on a ubuntu 8.04 i686 machine.

[Freesurfer] How to threshold an input mutli-volume?
Hi, all. Can mri_threshold threshold an input mutli-volume file? With a seven volumes NIFTI file, all voxels other than in the first volume are set to zero. In addition, the help for mri_threshold options is very limited. There is nothing about the options. Usage: mri_threshold [options] This program will threshold an input volume Where do I get more detailed description? Best Regards. ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
Re: [Freesurfer] How to "Fitting Tensors" in dt_recon?
Thank you very much. In fact, I want to insert the bet module before calculating the tensor, eigvals, eigvecs, fa, ra etc in dt_recon. I also know mri_glmfit can create glm-related images. But I can't find the tensor calculation in (mri_glmfit --y $fec --glmdir $OutDir --dti $bvals $bvecs).

[Freesurfer] How to "Fitting Tensors" in dt_recon?
Hi, All. The related item of "Fitting Tensors" is listed from the dt_recon. # Fit tensors echo "#...@#---" | tee -a $LF echo "Fitting Tensors" | tee -a $LF date | tee -a $LF set cmd = (mri_glmfit --y $fec --glmdir $OutDir); if($#bvals == 0) then set cmd = ($cmd --dti $infodump) else set cmd = ($cmd --dti $bvals $bvecs) endif However, I can't find any description about this argument(--dti) in mri_glmfit. Did the mri_glmfit call the dtifit to fit the tensor from fsl?If not, what is it? -- Albert Lab of Complex System and Artificial Intelligence, Institute of Automation,Chinese Academy of Sciences(CASIA) Beijing, 100190,P.R.CHINA ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
