Dear Doug, I want you could give me some guidances with my retinotopic analysis.

Eccen run: TR 2 Ncycles 6, 64 sec per cycle, all scan 384 sec. Polar run: TR 2, then follow Ncycles 10, 32 sec per cycle, all scan 320 sec.

I write the rtopy.par: stimtype polar diretion neg ncycles 10

and stimtype eccen diretion pos ncycles 6

My question is: How to set the value of -retinotopy in the mkanalysis as the eccen value should be -retinotopic 64 while the polar value should be -retinotopic 32 in the mkanalysis-sess Thanks a lot!

Yours Yufeng
