[Freesurfer] A question concerning optseq2

Hi, I have a question concerning the use of optseq2 to optimize my trial presentation. I am designing a task which consists of the presentation of a probe followed by feedback. I am interested in jittering both the ISI (between the probe and feedback) and the ITI (between each trial). Sadly, my

Re: [Freesurfer] A question concerning optseq2

I don't think you can do it with optseq2 out of the box. Part of it's purpose is to randomize the sequence of the events, but you need a fixed sequence. You can tell optseq that there is only one event and then go recode them into two events yourself. You can test the resulting efficiency with

Re: [Freesurfer] Questions about new release

Hi, thanks for your help. In reference to the centos_x86_64 build, is the output in 32 or 64 bit? The file sizes for the output for the redhat and centos builds were of similar size so I am assuming both are in 32 bit, but I wanted to confirm this, thanks, JeffOn 3/28/06, Nick Schmansky [EMAIL

[Freesurfer] MNI coords

Hi, I need to manually specify a seed point for the corpus callosum cutting plane on some of my images, although some of them don't seem to have the MNI coordiates available through clicking view information in tkmedit. Not sure why this is the case, since other images do have this info.

Re: [Freesurfer] MNI coords

Hi Alex, try volume scanner coords for the subjects that don't have the MNI coords. Sorry, I know this is more confusing than it needs to be. In the new version you just specify voxel coords :) Bruce On Thu, 30 Mar 2006, Fornito, Alexander wrote: Hi, I need to manually specify a seed
