[Freesurfer] Two FS versions in different user accounts
Hi everyone, I'm sorry to bring this question up again, but I'm thinking to install version 5.1 in the same computer where version 5.0 is installed. However I'm thinking of installing the new one in another user account that I've created only for this porpuse. My question is, can I install and work in the new user independently? This way I won't need to be changing the subjects dir and the freesurfer environment each time I want to work with 5.0 or 5.1, right? Advice needed =) Thanks, Andreia ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.

Re: [Freesurfer] Two FS versions in different user accounts
Hi Andreia yes, that should be fine. You really just need to change FREESURFER_HOME and the associated binary paths to use one version or the other. cheers Bruce On Fri, 27 Jan 2012, _andre...@sapo.pt wrote: Hi everyone, I'm sorry to bring this question up again, but I'm thinking to install version 5.1 in the same computer where version 5.0 is installed.

[Freesurfer] control point guidance
Hi guys, We are currently trying to fix some errors in the white/pial surfaces where there are thin white matter strands by using control points, and are noticing a couple things: 1) The resulting WM surface in the area of the CPs can end up too far into the GM instead. Given that, is there any practical guidance for how to think about the surrounding spatial extent that is impacted by a given CP? i.e., How do CP's actually get used within mri_normalize in an algorithmic sense? 2) The surfaces are being impacted in places distant from the CPs. e.g., CP's placed in the left anterior temporal lobe are resulting in surface changes in the right anterior temporal lobe. And when I difference the original norm.mgz vs. the one obtained after using CP's, I'm seeing an odd pattern of intensity differences which is clearly not limited to just the area of the CP's (which would be my expectation). This is version 5.1. thanks, -MH -- Michael Harms, Ph.D. Conte Center for the Neuroscience of Mental Disorders Washington University School of Medicine Department of Psychiatry, Box 8134 Renard Hospital, Room 6604 Tel: 314-747-6173 660 South Euclid Ave.Fax: 314-747-2182 St. Louis, MO 63110 Email: mha...@wustl.edu ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.

Re: [Freesurfer] control point guidance
Hi Michael, I had the same problem too. It might be because of the type of scanner you are using. I added -washu_mprage flag, it pretty much helped me (I did not had to add a lot of controls points and so on so forth.

Re: [Freesurfer] how can I view and process Freesurfer files using AFNI
Hello Rashmi, This is an AFNI issue. You'll have to read the SUMA manual and convert your Freesurfer files to AFNI-readable surfaces using @SUMA_Make_Spec_FS and other commands. There are too many steps to list here, but it is not too difficult once you get the hang of it.

Re: [Freesurfer] control point guidance
Hi Mike it's a bit hard to state the region of effect for the control points. Essentially we go through and label voxels as control points or not based on their intensity, intensity gradient and connectivity (that is, the must be 6-connected to other control points) then build a Voronoi diagram and each control point sets the scaling for its Voronoi triangle. Thus if you have a control point surrounded by others its region of effect is small, but one control point all by itself can have a large region of effect. Also, 5.1 applies the manually specified control points to the aseg normalization (norm.mgz), whereas older versions didn't. Not everyone is happy with this, so I think there is a backwards compatibility flag. Nick would know. Bruce On Fri, 27 Jan 2012, Sabin Khadka wrote: Hi Michael,I had the same problem too.
