Since I am a windows user I got the Virtualbox version of FreeSurfer and to use
fs fast, I installed Octave on the virtual machine, I set the environment
variables and then when I run the command
selxavg3-sess -analysis rtopy.lh -sf sessid
which runs a retinotopy analysis, I get the following e
Yes, it exists in the location you mentioned…

Does fast_fileexists.m exist in $FREESURFER_HOME/fsfast/toolbox ?

While I fix the virtual machine issues, I tried to use freesurfer on a cluster
machine which has matlab and FSL.
Problem is, when I executed fast_selxavg3 preprocessing is done but when matlab
gets started it gives me a message of matlab command not found.
When I type matlab in the terminal it
Hi all,
I am currently working on retinotopy data and I managed to get the maps but I
don’t really understand the angle meanings in the polar case. Like is zero
angle meaning horizontal or vertical stimulus.
The reason it is puzzling me is that I seem to get response over the whole 360
degree
Dear all,
I am wondering about the template that I should use for use to convert custom
made labels to volumes. I have used the template.nii.gz file that gets
generated in the fMRI analysis folder corresponding to the same subject along
with the register.dat file located in the same location.
I used tksurfer…
I found the error actually it was due to the order by which I load the data
into freeview. It has to be loading the ROI first and then loading the volume
along with the associated registry. When this order is violated all sorts of
problems happen.
On the other hand, I am unable
Dear all,
I am wondering about what the zero angle for retinotopy corresponds to in
retinotopy analysis. I mean corresponding to the wedge being at zero angle in
circular coordinate map (horizontal) or vertical up?
Thank you,

Thanks,
I am currently trying to figure out a way to translate the data I get out of FS
which defaults to a single rotating wedge to my double wedge experiment. It
seems to me that the positive and negative angles are reversed for each
hemisphere.
Does FS do some kind of mirroring for angles fo
