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
