I have only something similar in the temporal dynamics to the eccentricity data. I attached the Xtmp.mat file. Thank you!

Do you have both polar and eccen data? If so, can you send the Xtmp.mat file?

Hi Freesurfer experts,

I'm re-posting this message because I think it got lost.

I'm trying to analyze some phase-encoded data with the eccentricity protocol for retinotopic data and I'm having troubles with selxavg3-sess.

I run the following commands:

mkanalysis-sess -analysis OrderDisorder.idsubj.lh -surface idsubj lh -TR 2 -retinotopy 24 -paradigm rtopy.par -fwhm 0 -per-run -nskip 5 -fsd bold

selxavg3-sess -a OrderDisorder.idsubj.lh -s idsubj_OrderDisorder_continous

and I got this error message:

Sorry for the delay. Do you have polar angle data? Unfortunately, FSFAST needs both. If you don't have polar, just copy the eccen data and call it polar. for what you want to do it won't make much difference.
