Re: [Freesurfer] CUDA vs. ATI Stream / OpenCL

2010-08-24 Thread Gergely Orsi
Hi Nick, We are planning to buy a GTX 460 1G card because of the cuda support of Freesurfer. It seems the most reasonable buy for CUDA device, 336 Core, 1350MHZ shader, and around 100 $ cheaper than the 285GTX. Does this card has double precision support? And what is you guess (time) about the

[Freesurfer] Notes on CUDA Acceleration

2010-08-24 Thread Richard G. Edgar
Greetings, I've been asked to provide some extra information about GPU support in Freesurfer (being the one guilty of mri_em_register_cuda...). Firstly, there are no immediate plans for OpenCL support. It would be very nice to have - with ATI, NVIDIA _and_ x86 multicore backends. However, it's

since we'll be providing updates to these _cuda binaries (in the form of the fscudabins_linuc_centos4*.tgz tarballs), i'll make sure they are built with the 1.1 architecture in our stable branch. i'm thinking our plan will be to conform to the 1.1 architecture for the near term stable release

no sure about that error, but clearly we need to look at that devicemanagement.cu code as it seems to be the gate keeper to getting anything running. we'll see if we can get that code to produce some useful error message and post a new _cuda tarball. n. On Tue, 2010-08-24 at 11:48 -0400,

Hi, there, Thanks a lot for your help, now I have attached the new vdi to the old vid, but I still can not access the new space after I restart the old vdi. I searched online, it looks like I'd use some software to clone the old vdi to the new vdi, then set the new vdi as the primary master,

[Freesurfer] How to add volume on pial surface in manual editting the trouble shootings

2010-08-24 Thread 李瑾
Dear freesurferers I have faced a problem in editing pial surface in trouble shootings. Since the page https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/PialEdits has showed how to delete volume which is really useful, however, we faced another problem, that is how to add volume. I selected the

2010-08-24 Thread Douglas N Greve
we don't actually have a way to edit the pial surface. Usually, the problem you describe is an intensity normalization problem, so you might want to put some control points near the place where the pial surface is in error. Be careful putting in the control points. You want to make sure that

Hi Jin you have to identify the problem. Is it that the white matter surface is incorrect so the pial doesn't get out far enough? Are the intensites in the wm and gm darker in that region? Is there a gm leson? If you upload the dataset we'll take a look cheers Bruce On Tue, 24 Aug 2010,
