Virtualtoolbox
by Liukarl 29 Dec '10

29 Dec '10

Hello, Freesurfer users: I am new to Freesurfer. I have two questions when I tried to install the Virtualtoolbox-Freesurfer into Window-XP system. 1) I downloaded the VirtualBox 4.0 for Windows hosts, but in the step of “Adding the downloaded hard disk image”, there is no “Add” button that I can use add the disk image. Any idea how to fix this? 2) Say, eventually I successfully installed it. I have some other data from another Mac that I need to transfer to this windows computer. What folder I should put in my data that comply with the default SUBJECTS_DIR for further analysis? Thanks a lot! Karl

pial surface in v5.0
by Lena Palaniyappan 28 Dec '10

I am not able to run recon-all localGI in v5.0 and I suspect this has something to do with the way pial surfaces are produced in v5.0 (the mris_make_surfaces bug) ERROR: compute_lgi did not create output file '/Volumes/FREECOM/Applications/freesurfer/subjects/conn/conn02/surf/tmp-mris_compute_lgi-lh.pial/lh.pial_lgi.asc'!

bad output of autorecon2 - is there any way to adjust it?
by Paola Valsasina 28 Dec '10

28 Dec '10

Dear Freesurfer experts, I have tried to analyze with Freesurfer a dataset of images acquired with a 3D T1 sequence without inversion pulse (unfortunately, it is simply a FFE sequence and not a MP-RAGE). Contrast between grey and white matter is not optimal in this image, and when I run -autorecon2 step I obtain a very bad output (attached). "white/grey" surface seems to be where the pial surface is expected to be, and pial surface is in the middle of csf. In your opinion, is it possible to obtain meaningful results with these images or not? Is there any setting of post-processing that I can change in order to obtain better surfaces? Thank you for any suggestion Kind regards, Paola ----------------------------------------------------------------------------------- SOSTIENI ANCHE TU LA RICERCA DEL SAN RAFFAELE.

missed label in cortical parcellation
by Anh Tuan 26 Dec '10

26 Dec '10

Dear Freesurfer users, After cortical parcellation, somehow the precentral and postcentral areas are mixed up and I'm not sure what could have caused this. Attached is a snap shot for your reference. Appreciate any hint given. Thanks Anthony
