2.54          version of ri that this parameter file is designed for.
"Fis"         name of the ribl matrix
-10 +10       From-to range to do the evaluation
1             column of the values file to copy to xyin
a 0 1000      lowest to highest Ri to put in xyin and sequ (a = any)
a -1000 +1000 lowest to highest Value to put in xyin and sequ (a = any)
n             p means print sequence to the sequ file
p             p means print sequence to the xyin file
-             -: accept all sites; n: no partials; i: partials -> -infinity
s 2           s: use Staden's Method, f(b,l)=1/(n+t); else negative infinity
