[Freesurfer] accounting for BOLD response lag in FS retinotopy analysis

eriod is longer than it actually is. If there exists an example design matrix for the retinotopy analysis, that would also be useful. Thanks, Jeff Phillips University of Pittsburgh ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu

[Freesurfer] retinotopy and alternating stimulus direction within-run

Hello all, I am wondering if the FS FAST retinotopy analysis can deal with within-run alternations of stimulus direction. I have collected data in which eccentricity and polar angle were manipulated in separate runs, but within each run, a cycle of stimulation in one direction was followed by a c

[Freesurfer] Re: drawing ROIs in surface space

Alright, perhaps I should revise my question--it seems like labels are the way to go for specifying ROIs. If that's the case, how do I convert a label file into a volume-space image? Thanks again, Jeff On Sat, Mar 7, 2009 at 2:09 PM, Jeff Phillips wrote: > Hello all, > > I am

Re: [Freesurfer] Can fieldsigns be added across sessions?

Sorry, one additional question: per your suggestion, I can handle adding/averaging the real and imaginary component masks, but what syntax can I use in paint-sess to convert those composite masks into fieldsign maps? Thanks, Jeff On Mon, May 11, 2009 at 12:40 PM, Jeff Phillips

Re: [Freesurfer] Can fieldsigns be added across sessions?

lly useful to us, as it seems like some combination of low statistical power and the operation of the fieldsign algorithm could be causing the between-session inconsistencies in our maps. Thanks, Jeff On Mon, May 11, 2009 at 8:45 PM, Douglas N Greve wrote: > > > Jeff Phillips
