Hi Jon, Thanks!
I have a question about when selfreqavg. When do I use selfreqavg? Is it called when I run fieldsign-sess or do I have to run it in addition to the below?
I've been doing the following:
mkanalysis-sess -a rtopy.self.lh -surface self lh -TR 2 -retinotopy 48 -paradigm rtopy.par -nskip 4 -fwhm 0 -force mkanalysis-sess -a rtopy.self.rh -surface self rh -TR 2 -retinotopy 48 -paradigm rtopy.par -nskip 4 -fwhm 0 -force
preproc-sess -surface self lhrh -fwhm 5 -per-run -s sj09 -force
selxavg3-sess -a rtopy.self.lh -s sj09 selxavg3-sess -a rtopy.self.rh -s sj09 fieldsign-sess -a rtopy.self.lh -occip -s sj09 fieldsign-sess -a rtopy.self.rh -occip -s sj09
Thanks for your help. Michelle

hi michelle,
the Sereno et al. 1995 Science paper has details about the phase encoded retinotopic data analysis, especially in the endnotes of the article. also for more details you can look at the MATLAB code embedded in the command 'selfreqavg', which is used for the basic retinotopy analysis and is quite readable.
hope this helps,

Hi Freesurfers. Is there text describing the retinotopy analysis in Freesurfer mathematically?
Thanks. Michelle
