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:
