hi lars,
the FSFast retinotopy analysis stream is geared towards temporal phase
encoded data analysis, which produces field sign maps that can be used to
define area boundaries.
if you opt to use stationary wedge stimuli to activate the horizontal and
vertical meridian representations in visual
I have a relatively new program that does this. Actually, it is an old
program with a cryptic name (mri_cor2label). I've put a new (linux)
version here:
ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_cor2label
See the help.
I don't know why mri_mergelabels does not work.
Which fsgd file are you loading? If you're not already, load the one in
the glmdir

I think you can do it in the tksurfer drawing interface (click the "add

Hi Bruce,
Thanks for your email. We are actually interested in looking at k though
and I was wondering what surfaces you use for the numerator and denominator.

Hi Morgan,
I think mris_jacobian computes and applies the scale factor for you. The
group average surface area is the average surface area of the individuals
that went into the group, since the average subject has less surface area
than any of the individuals. Doug uses this to compute the pro
Hi there,
I would like to ask some questions about metric distortion.
1. Following the Wisco et al (2007) paper, metric distortion is defined as
Metric Distortion = k * area of a triangle on a registered sphere / area
of triangle on gray/white interface surface
which I believe I can compute
Hi all,
I used a retinotopy paradigm with two horizontal and vertical wedges
located at the meridians (flickering at 8Hz, switching every 20 seconds)
do you think that this paradigm does fit into fsfastretinotopy analysis?
I'm not sure if it makes a difference compared to rotating edges...

This is one of those ugly, "not officially supported" things:
set gaHistogramData(threshMode) linear-opaque
set gaLinedVars(fopaqueflag) 1

Hello,
Does anyone know if it is possible to set the overlay threshold to
"linear opaque" mode in tksurfer using TCL commands? I looked at the
documentation, and I didn't see a method explicitly for that purpose,
but maybe there is some way to specify that option.
Thanks,
Rob
