Inaccurate transformation
by Shani Ben Amitay 03 Feb '13

03 Feb '13

Dear freesurfers I used bbregister to coregister diffusion images with anatomical. I would like to apply the bbregistration transformation to the white and pial surfaces What I've done is: I calculated new transformation matrix using fs_read_dat.m and then apply it to the surfaces with mri_surf2surf. When overlaying the new surface on the diffusion data- it seems that the transformation is inaccurate.(screenshot is attached) Any idea why?. Thanks, Shani

FS 5.2-beta run-times on Amazon Web services (AWS)
by Mehul Sampat 02 Feb '13

02 Feb '13

Hi Folks, Just wanted to share our experience with running FS 5.2-beta on Amazon Web Services (AWS). Basically, AWS has multiple instance types ( http://aws.amazon.com/ec2/instance-types/) and we were trying to figure out the most cost-effective approach. We ran two subjects through FS 5.2-beta on M1 Large Instance (m1.large) and Cluster Compute Eight Extra Large Instance (cc2.8xlarge). (same subjects run on both instance). We expected cc2.8xlarge to be faster (but it is also more expensive: $2.4 per hour; 8 cores); The run-times we got: instance-type subject start-time end-time run-time m1.large subject-1 01:05:44 UTC 2013 15:40:45 UTC 2013 *~14hr-35mins* m1.large subject-2 01:06:06 UTC 2013 15:08:45 UTC 2013 *~14hr-02mins * cc2.8xlarge subject-1 01:26:38 UTC 2013 12:30:23 UTC 2013 *~11hr-04mins* cc2.8xlarge subject-2 01:27:28 UTC 2013 12:19:08 UTC 2013 *~10hr-52mins* Although m1.large is a few hours slower, it seems to be the more cost effective option since it is $0.24 per hour (2 cores). If you have run Freesurfer on AWS, do you have a similar experience ? Any suggestions to speed up the run-times on AWS would be very helpful. Thanks Mehul

Freesurfer parcellations: raw MRI or after resetting the origin?
by Sudhin A. Shah 02 Feb '13

02 Feb '13

Hello, I have been running Freesurfer parcellations on my raw MRI. Is it better to first reset the origin (Step 5 herehttp://www.mccauslandcenter.sc.edu/CRNL/sw/tutorial/html/eventspm.html) BEFORE parcellating? Thanks, S
