[Freesurfer] orientation in freeview

Hi all, I have a problem maybe relevant to the orientation of images in freeview. I have two images, one is fMRI and one is MRI. They are produced from the same machine at the same time. I loaded both of them in freeview and it showed they are matched very well, even they have different

Re: [Freesurfer] Topup before trac-all

Hi - Running topup is not a problem. Just make sure that there's as many entries in the gradient table and b-value table as there are frames in the DWI file. So if with topup you're combining 2 sets of DWIs (collected with opposite phase-encode directions), you also have to combine the

[Freesurfer] Control points and WM edits

Hello Freesurfer, I played around with mri_normalize for control point section by changing the parameters using -b 20 or 23 and writing it in an expert file. However, when I ran recon-all -autorecon2-cp -autorecon3 -expert expert.opts, the command showed "mri_normalize - mprage -noconform )

[Freesurfer] Topup before trac-all

Hi, I would like to preprocess my dti data with topup (from FSL) before running trac-all. Is this a sensible approach? When I tried running trac-all -prep with the output file from topup (*_hifi_nodif.nii.gz) I got an error message: mv -f /usit/abel/<>/topuop/146/dmri/bvecs

Re: [Freesurfer] mrisComputeCorrelationTerm: delta is not finite at vno 0

The same thing happened to me on my mac when I changed the FREESURFER_HOME variable in the terminal, but not in the .bashrc file that I source when the terminal opens. Hope this helps! Thanks, Doug Douglas Merkitch Neurological Sciences Rush University Medical Center On Feb 9, 2017, at

Re: [Freesurfer] mrisComputeCorrelationTerm: delta is not finite at vno 0

Hello Juhyoung, If its complaining about "RB_all_2008-03-26.gca" then something must have happened where you still have portions of the old freesurfer installed, or your mixing versions because Freesurfer v6 has no mention of RB_all_2008-03-26.gca. Please try completely removing the

It says that it was "Killed" which sounds like the job exceeded some resource on the supercomputer. You should contact the administrators to see what the limits are and whether you exceeded them. You can also run the same subject on a regular computer and see if it dies in the same place. On

[Freesurfer] Fwd: LGI using Yeo Atlas

Re: [Freesurfer] Expert file for recon-all -hires

Hi Chris the smaller the voxels the more you will need to inflate. I'm hoping to find some time to make this adaptive as in principal it's all computable, but haven't gotten to it yet. cheers Bruce On Thu, 9 Feb 2017, Christopher Markiewicz wrote: > Hi all, > > If I'm reading this >

Re: [Freesurfer] Expert file for recon-all -hires

Dear Chris and Antonin, I found in some archived message or in the wiki that the default used to be 50 iterations at some time in previous releases of FreeSurfer for standard recon-all. Therefore, I changed it to 50 as default for every resolution in the recent release. This works fine for

Re: [Freesurfer] recon-all -localGI with longitudinal pipeline output

Hi Mihaela, probably you are trying to run the localGI on a longitudinal directory. As the help text output says, you need to make sure you tell that to recon-al by passing the original command again (including the -long ….) and instead of -all you specify -localGI. Renaming hides from

Re: [Freesurfer] Edits to Aseg in the Longitudinal Stream

Hi Tamara, that depends on where you edit. Cross or base or long. Generally when editing in the longitudinal stream you always use the same recon-all command that you used initially, and only replace the -all with the new flag to tell it to start later in the process (here -autorecon2-noaseg

Hi Matthieu, sorry for the late reply. Yes you should be able to do that (as long as it is consistent for all subjects). Test it for one subject and then run the rest. Best, Martin > On 30 Jan 2017, at 16:51, Matthieu Vanhoutte > wrote: > > Dear experts, > >

[Freesurfer] Parallelization implementation in Freesurfer 6.0

Dear FreeSurfer developers, I am a new FreeSurfer user and I am trying to run it in a supercomputer for the first time. Recon-all finished with errors (see log attached) during skull stripping. I have searched the archives and only found that it could be a memory problem, but I am unsure
